# Auth - Authentication and User Management by Supabase
[](https://coveralls.io/github/supabase/gotrue?branch=master)
Auth is a user management and authentication server written in Go that powers
[Supabase](https://supabase.com)'s features such as:
- Issuing JWTs
- Row Level Security with PostgREST
- User management
- Sign in with email, password, magic link, phone number
- Sign in with external providers (Google, Apple, Facebook, Discord, ...)
It is originally based on the excellent
[GoTrue codebase by Netlify](https://github.com/netlify/gotrue), however both have diverged significantly in features and capabilities.
If you wish to contribute to the project, please refer to the [contributing guide](/CONTRIBUTING.md).
## Table Of Contents
- [Quick Start](#quick-start)
- [Running in Production](#running-in-production)
- [Configuration](#configuration)
- [Endpoints](#endpoints)
## Quick Start
Create a `.env` file to store your own custom env vars. See [`example.env`](example.env)
1. Start the local postgres database in a postgres container: `docker-compose -f docker-compose-dev.yml up postgres`
2. Build the auth binary: `make build` . You should see an output like this:
```
go build -ldflags "-X github.com/supabase/auth/cmd.Version=`git rev-parse HEAD`"
GOOS=linux GOARCH=arm64 go build -ldflags "-X github.com/supabase/auth/cmd.Version=`git rev-parse HEAD`" -o gotrue-arm64
```
3. Execute the auth binary: `./gotrue`
### If you have docker installed
Create a `.env.docker` file to store your own custom env vars. See [`example.docker.env`](example.docker.env)
1. `make build`
2. `make dev`
3. `docker ps` should show 2 docker containers (`auth_postgresql` and `gotrue_gotrue`)
4. That's it! Visit the [health checkendpoint](http://localhost:9999/health) to confirm that auth is running.
## Running in production
Running an authentication server in production is not an easy feat. We
recommend using [Supabase Auth](https://supabase.com/auth) which gets regular
security updates.
Otherwise, please make sure you setup a process to promptly update to the
latest version. You can do that by following this repository, specifically the
[Releases](https://github.com/supabase/auth/releases) and [Security
Advisories](https://github.com/supabase/auth/security/advisories) sections.
### Backward compatibility
Auth uses the [Semantic Versioning](https://semver.org) scheme. Here are some
further clarifications on backward compatibility guarantees:
**Go API compatibility**
Auth is not meant to be used as a Go library. There are no guarantees on
backward API compatibility when used this way regardless which version number
changes.
**Patch**
Changes to the patch version guarantees backward compatibility with:
- Database objects (tables, columns, indexes, functions).
- REST API
- JWT structure
- Configuration
Guaranteed examples:
- A column won't change its type.
- A table won't change its primary key.
- An index will not be removed.
- A uniqueness constraint will not be removed.
- A REST API will not be removed.
- Parameters to REST APIs will work equivalently as before (or better, if a bug
has been fixed).
- Configuration will not change.
Not guaranteed examples:
- A table may add new columns.
- Columns in a table may be reordered.
- Non-unique constraints may be removed (database level checks, null, default
values).
- JWT may add new properties.
**Minor**
Changes to minor version guarantees backward compatibility with:
- REST API
- JWT structure
- Configuration
Exceptions to these guarantees will be made only when serious security issues
are found that can't be remedied in any other way.
Guaranteed examples:
- Existing APIs may be deprecated but continue working for the next few minor
version releases.
- Configuration changes may become deprecated but continue working for the next
few minor version releases.
- Already issued JWTs will be accepted, but new JWTs may be with a different
structure (but usually similar).
Not guaranteed examples:
- Removal of JWT fields after a deprecation notice.
- Removal of certain APIs after a deprecation notice.
- Removal of sign-in with external providers, after a deprecation notice.
- Deletion, truncation, significant schema changes to tables, indexes, views,
functions.
We aim to provide a deprecation notice in execution logs for at least two major
version releases or two weeks if multiple releases go out. Compatibility will
be guaranteed while the notice is live.
**Major**
Changes to the major version do not guarantee any backward compatibility with
previous versions.
### Inherited features
Certain inherited features from the Netlify codebase are not supported by
Supabase and they may be removed without prior notice in the future. This is a
comprehensive list of those features:
1. Multi-tenancy via the `instances` table i.e. `GOTRUE_MULTI_INSTANCE_MODE`
configuration parameter.
2. System user (zero UUID user).
3. Super admin via the `is_super_admin` column.
4. Group information in JWTs via `GOTRUE_JWT_ADMIN_GROUP_NAME` and other
configuration fields.
5. Symmetrics JWTs. In the future it is very likely that Auth will begin
issuing asymmetric JWTs (subject to configuration), so do not rely on the
assumption that only HS256 signed JWTs will be issued long term.
Note that this is not an exhaustive list and it may change.
### Best practices when self-hosting
These are some best practices to follow when self-hosting to ensure backward
compatibility with Auth:
1. Do not modify the schema managed by Auth. You can see all of the
migrations in the `migrations` directory.
2. Do not rely on schema and structure of data in the database. Always use
Auth APIs and JWTs to infer information about users.
3. Always run Auth behind a TLS-capable proxy such as a load balancer, CDN,
nginx or other similar software.
## Configuration
You may configure Auth using either a configuration file named `.env`,
environment variables, or a combination of both. Environment variables are prefixed with `GOTRUE_`, and will always have precedence over values provided via file.
### Top-Level
```properties
GOTRUE_SITE_URL=https://example.netlify.com/
```
`SITE_URL` - `string` **required**
The base URL your site is located at. Currently used in combination with other settings to construct URLs used in emails. Any URI that shares a host with `SITE_URL` is a permitted value for `redirect_to` params (see `/authorize` etc.).
`URI_ALLOW_LIST` - `string`
A comma separated list of URIs (e.g. `"https://foo.example.com,https://*.foo.example.com,https://bar.example.com"`) which are permitted as valid `redirect_to` destinations. Defaults to []. Supports wildcard matching through globbing. e.g. `https://*.foo.example.com` will allow `https://a.foo.example.com` and `https://b.foo.example.com` to be accepted. Globbing is also supported on subdomains. e.g. `https://foo.example.com/*` will allow `https://foo.example.com/page1` and `https://foo.example.com/page2` to be accepted.
For more common glob patterns, check out the [following link](https://pkg.go.dev/github.com/gobwas/glob#Compile).
`OPERATOR_TOKEN` - `string` _Multi-instance mode only_
The shared secret with an operator (usually Netlify) for this microservice. Used to verify requests have been proxied through the operator and
the payload values can be trusted.
`DISABLE_SIGNUP` - `bool`
When signup is disabled the only way to create new users is through invites. Defaults to `false`, all signups enabled.
`GOTRUE_EXTERNAL_EMAIL_ENABLED` - `bool`
Use this to disable email signups (users can still use external oauth providers to sign up / sign in)
`GOTRUE_EXTERNAL_PHONE_ENABLED` - `bool`
Use this to disable phone signups (users can still use external oauth providers to sign up / sign in)
`GOTRUE_RATE_LIMIT_HEADER` - `string`
Header on which to rate limit the `/token` endpoint.
`GOTRUE_RATE_LIMIT_EMAIL_SENT` - `string`
Rate limit the number of emails sent per hr on the following endpoints: `/signup`, `/invite`, `/magiclink`, `/recover`, `/otp`, & `/user`.
`GOTRUE_PASSWORD_MIN_LENGTH` - `int`
Minimum password length, defaults to 6.
`GOTRUE_PASSWORD_REQUIRED_CHARACTERS` - a string of character sets separated by `:`. A password must contain at least one character of each set to be accepted. To use the `:` character escape it with `\`.
`GOTRUE_SECURITY_REFRESH_TOKEN_ROTATION_ENABLED` - `bool`
If refresh token rotation is enabled, auth will automatically detect malicious attempts to reuse a revoked refresh token. When a malicious attempt is detected, gotrue immediately revokes all tokens that descended from the offending token.
`GOTRUE_SECURITY_REFRESH_TOKEN_REUSE_INTERVAL` - `string`
This setting is only applicable if `GOTRUE_SECURITY_REFRESH_TOKEN_ROTATION_ENABLED` is enabled. The reuse interval for a refresh token allows for exchanging the refresh token multiple times during the interval to support concurrency or offline issues. During the reuse interval, auth will not consider using a revoked token as a malicious attempt and will simply return the child refresh token.
Only the previous revoked token can be reused. Using an old refresh token way before the current valid refresh token will trigger the reuse detection.
### API
```properties
GOTRUE_API_HOST=localhost
PORT=9999
API_EXTERNAL_URL=http://localhost:9999
```
`API_HOST` - `string`
Hostname to listen on.
`PORT` (no prefix) / `API_PORT` - `number`
Port number to listen on. Defaults to `8081`.
`API_ENDPOINT` - `string` _Multi-instance mode only_
Controls what endpoint Netlify can access this API on.
`API_EXTERNAL_URL` - `string` **required**
The URL on which Gotrue might be accessed at.
`REQUEST_ID_HEADER` - `string`
If you wish to inherit a request ID from the incoming request, specify the name in this value.
### Database
```properties
GOTRUE_DB_DRIVER=postgres
DATABASE_URL=root@localhost/auth
```
`DB_DRIVER` - `string` **required**
Chooses what dialect of database you want. Must be `postgres`.
`DATABASE_URL` (no prefix) / `DB_DATABASE_URL` - `string` **required**
Connection string for the database.
`GOTRUE_DB_MAX_POOL_SIZE` - `int`
Sets the maximum number of open connections to the database. Defaults to 0 which is equivalent to an "unlimited" number of connections.
`DB_NAMESPACE` - `string`
Adds a prefix to all table names.
**Migrations Note**
Migrations are applied automatically when you run `./auth`. However, you also have the option to rerun the migrations via the following methods:
- If built locally: `./auth migrate`
- Using Docker: `docker run --rm auth gotrue migrate`
### Logging
```properties
LOG_LEVEL=debug # available without GOTRUE prefix (exception)
GOTRUE_LOG_FILE=/var/log/go/auth.log
```
`LOG_LEVEL` - `string`
Controls what log levels are output. Choose from `panic`, `fatal`, `error`, `warn`, `info`, or `debug`. Defaults to `info`.
`LOG_FILE` - `string`
If you wish logs to be written to a file, set `log_file` to a valid file path.
### Observability
Auth has basic observability built in. It is able to export
[OpenTelemetry](https://opentelemetry.io) metrics and traces to a collector.
#### Tracing
To enable tracing configure these variables:
`GOTRUE_TRACING_ENABLED` - `boolean`
`GOTRUE_TRACING_EXPORTER` - `string` only `opentelemetry` supported
Make sure you also configure the [OpenTelemetry
Exporter](https://opentelemetry.io/docs/reference/specification/protocol/exporter/)
configuration for your collector or service.
For example, if you use
[Honeycomb.io](https://docs.honeycomb.io/getting-data-in/opentelemetry/go-distro/#using-opentelemetry-without-the-honeycomb-distribution)
you should set these standard OpenTelemetry OTLP variables:
```
OTEL_SERVICE_NAME=auth
OTEL_EXPORTER_OTLP_PROTOCOL=grpc
OTEL_EXPORTER_OTLP_ENDPOINT=https://api.honeycomb.io:443
OTEL_EXPORTER_OTLP_HEADERS="x-honeycomb-team=,x-honeycomb-dataset=auth"
```
#### Metrics
To enable metrics configure these variables:
`GOTRUE_METRICS_ENABLED` - `boolean`
`GOTRUE_METRICS_EXPORTER` - `string` only `opentelemetry` and `prometheus`
supported
Make sure you also configure the [OpenTelemetry
Exporter](https://opentelemetry.io/docs/reference/specification/protocol/exporter/)
configuration for your collector or service.
If you use the `prometheus` exporter, the server host and port can be
configured using these standard OpenTelemetry variables:
`OTEL_EXPORTER_PROMETHEUS_HOST` - IP address, default `0.0.0.0`
`OTEL_EXPORTER_PROMETHEUS_PORT` - port number, default `9100`
The metrics are exported on the `/` path on the server.
If you use the `opentelemetry` exporter, the metrics are pushed to the
collector.
For example, if you use
[Honeycomb.io](https://docs.honeycomb.io/getting-data-in/opentelemetry/go-distro/#using-opentelemetry-without-the-honeycomb-distribution)
you should set these standard OpenTelemetry OTLP variables:
```
OTEL_SERVICE_NAME=auth
OTEL_EXPORTER_OTLP_PROTOCOL=grpc
OTEL_EXPORTER_OTLP_ENDPOINT=https://api.honeycomb.io:443
OTEL_EXPORTER_OTLP_HEADERS="x-honeycomb-team=,x-honeycomb-dataset=auth"
```
Note that Honeycomb.io requires a paid plan to ingest metrics.
If you need to debug an issue with traces or metrics not being pushed, you can
set `DEBUG=true` to get more insights from the OpenTelemetry SDK.
#### Custom resource attributes
When using the OpenTelemetry tracing or metrics exporter you can define custom
resource attributes using the [standard `OTEL_RESOURCE_ATTRIBUTES` environment
variable](https://opentelemetry.io/docs/reference/specification/resource/sdk/#specifying-resource-information-via-an-environment-variable).
A default attribute `auth.version` is provided containing the build version.
#### Tracing HTTP routes
All HTTP calls to the Auth API are traced. Routes use the parametrized
version of the route, and the values for the route parameters can be found as
the `http.route.params.` span attribute.
For example, the following request:
```
GET /admin/users/4acde936-82dc-4552-b851-831fb8ce0927/
```
will be traced as:
```
http.method = GET
http.route = /admin/users/{user_id}
http.route.params.user_id = 4acde936-82dc-4552-b851-831fb8ce0927
```
#### Go runtime and HTTP metrics
All of the Go runtime metrics are exposed. Some HTTP metrics are also collected
by default.
### JSON Web Tokens (JWT)
```properties
GOTRUE_JWT_SECRET=supersecretvalue
GOTRUE_JWT_EXP=3600
GOTRUE_JWT_AUD=netlify
```
`JWT_SECRET` - `string` **required**
The secret used to sign JWT tokens with.
`JWT_EXP` - `number`
How long tokens are valid for, in seconds. Defaults to 3600 (1 hour).
`JWT_AUD` - `string`
The default JWT audience. Use audiences to group users.
`JWT_ADMIN_GROUP_NAME` - `string`
The name of the admin group (if enabled). Defaults to `admin`.
`JWT_DEFAULT_GROUP_NAME` - `string`
The default group to assign all new users to.
### External Authentication Providers
We support `apple`, `azure`, `bitbucket`, `discord`, `facebook`, `figma`, `github`, `gitlab`, `google`, `keycloak`, `linkedin`, `notion`, `spotify`, `slack`, `twitch`, `twitter` and `workos` for external authentication.
Use the names as the keys underneath `external` to configure each separately.
```properties
GOTRUE_EXTERNAL_GITHUB_ENABLED=true
GOTRUE_EXTERNAL_GITHUB_CLIENT_ID=myappclientid
GOTRUE_EXTERNAL_GITHUB_SECRET=clientsecretvaluessssh
GOTRUE_EXTERNAL_GITHUB_REDIRECT_URI=http://localhost:3000/callback
```
No external providers are required, but you must provide the required values if you choose to enable any.
`EXTERNAL_X_ENABLED` - `bool`
Whether this external provider is enabled or not
`EXTERNAL_X_CLIENT_ID` - `string` **required**
The OAuth2 Client ID registered with the external provider.
`EXTERNAL_X_SECRET` - `string` **required**
The OAuth2 Client Secret provided by the external provider when you registered.
`EXTERNAL_X_REDIRECT_URI` - `string` **required**
The URI a OAuth2 provider will redirect to with the `code` and `state` values.
`EXTERNAL_X_URL` - `string`
The base URL used for constructing the URLs to request authorization and access tokens. Used by `gitlab` and `keycloak`. For `gitlab` it defaults to `https://gitlab.com`. For `keycloak` you need to set this to your instance, for example: `https://keycloak.example.com/realms/myrealm`
#### Apple OAuth
To try out external authentication with Apple locally, you will need to do the following:
1. Remap localhost to \ in your `/etc/hosts` config.
2. Configure auth to serve HTTPS traffic over localhost by replacing `ListenAndServe` in [api.go](api/api.go) with:
```
func (a *API) ListenAndServe(hostAndPort string) {
log := logrus.WithField("component", "api")
path, err := os.Getwd()
if err != nil {
log.Println(err)
}
server := &http.Server{
Addr: hostAndPort,
Handler: a.handler,
}
done := make(chan struct{})
defer close(done)
go func() {
waitForTermination(log, done)
ctx, cancel := context.WithTimeout(context.Background(), time.Minute)
defer cancel()
server.Shutdown(ctx)
}()
if err := server.ListenAndServeTLS("PATH_TO_CRT_FILE", "PATH_TO_KEY_FILE"); err != http.ErrServerClosed {
log.WithError(err).Fatal("http server listen failed")
}
}
```
3. Generate the crt and key file. See [here](https://www.freecodecamp.org/news/how-to-get-https-working-on-your-local-development-environment-in-5-minutes-7af615770eec/) for more information.
4. Generate the `GOTRUE_EXTERNAL_APPLE_SECRET` by following this [post](https://medium.com/identity-beyond-borders/how-to-configure-sign-in-with-apple-77c61e336003)!

Register a new user with a phone number and password.
```js
{
"phone": "12345678", // follows the E.164 format
"password": "secret"
}
```
Returns:
```json
{
"id": "11111111-2222-3333-4444-5555555555555", // if duplicate sign up, this ID will be faux

```
{
"code":400,
"msg":"User already registered"
}
```
### **POST /invite**
Invites a new user with an email.
This endpoint requires the `service_role` or `supabase_admin` JWT set as an Auth Bearer header:
e.g.
```json
headers: {
"Authorization" : "Bearer eyJhbGciOiJI...M3A90LCkxxtX9oNP9KZO"
}
```
```json
{
"email": "[email protected]"
}
```

"invited_at": "2016-05-15T19:53:12.368652374-07:00"
}
```
### **POST /verify**
Verify a registration or a password recovery. Type can be `signup` or `recovery` or `invite`
and the `token` is a token returned from either `/signup` or `/recover`.
```json
{
"type": "signup",
"token": "confirmation-code-delivered-in-email"
}
```
`password` is required for signup verification if no existing password exists.
Returns:
```json
{
"access_token": "jwt-token-representing-the-user",
"token_type": "bearer",
"expires_in": 3600,
"refresh_token": "a-refresh-token",
"type": "signup | recovery | invite"
}
```
Verify a phone signup or sms otp. Type should be set to `sms`.
```json
{
"type": "sms",
"token": "confirmation-otp-delivered-in-sms",
"redirect_to": "https://supabase.io",
"phone": "phone-number-sms-otp-was-delivered-to"
}
```
Returns:
```json
{
"access_token": "jwt-token-representing-the-user",
"token_type": "bearer",
"expires_in": 3600,
"refresh_token": "a-refresh-token"
}
```
### **GET /verify**
Verify a registration or a password recovery. Type can be `signup` or `recovery` or `magiclink` or `invite`
and the `token` is a token returned from either `/signup` or `/recover` or `/magiclink`.
query params:
```json
{
"type": "signup",
"token": "confirmation-code-delivered-in-email",
"redirect_to": "https://supabase.io"
}
```
User will be logged in and redirected to:
```json
SITE_URL/#access_token=jwt-token-representing-the-user&token_type=bearer&expires_in=3600&refresh_token=a-refresh-token&type=invite
```
Your app should detect the query params in the fragment and use them to set the session (supabase-js does this automatically)
You can use the `type` param to redirect the user to a password set form in the case of `invite` or `recovery`,
or show an account confirmed/welcome message in the case of `signup`, or direct them to some additional onboarding flow
### **POST /otp**
One-Time-Password. Will deliver a magiclink or sms otp to the user depending on whether the request body contains an "email" or "phone" key.
If `"create_user": true`, user will not be automatically signed up if the user doesn't exist.
```js
{
"phone": "12345678" // follows the E.164 format
"create_user": true
}
OR
// exactly the same as /magiclink
{
"email": "[email protected]"
"create_user": true
}
```
Returns:
```
{}
```
### **POST /magiclink** (recommended to use /otp instead. See above.)
Magic Link. Will deliver a link (e.g. `/verify?type=magiclink&token=fgtyuf68ddqdaDd`) to the user based on
email address which they can use to redeem an access_token.
By default Magic Links can only be sent once every 60 seconds
```json
{
"email": "[email protected]"
}
```
Returns:
```json
{}
```
when clicked the magic link will redirect the user to `#access_token=x&refresh_token=y&expires_in=z&token_type=bearer&type=magiclink` (see `/verify` above)
### **POST /recover**
Password recovery. Will deliver a password recovery mail to the user based on
email address.
By default recovery links can only be sent once every 60 seconds
```json
{
"email": "[email protected]"
}
```
Returns:
```json
{}
```
### **POST /token**
This is an OAuth2 endpoint that currently implements
the password and refresh_token grant types
query params:
```
?grant_type=password

{
"email": "[email protected]",
"password": "somepassword"
}
// Phone login
{
"phone": "12345678",
"password": "somepassword"
}
```
or
query params:
```
grant_type=refresh_token
```
body:
```json
{
"refresh_token": "a-refresh-token"
}
```
Once you have an access token, you can access the methods requiring authentication
by settings the `Authorization: Bearer YOUR_ACCESS_TOKEN_HERE` header.

{
"access_token": "jwt-token-representing-the-user",
"token_type": "bearer",
"expires_in": 3600,

}
```
### **PUT /user**
Update a user (Requires authentication). Apart from changing email/password, this
method can be used to set custom user data. Changing the email will result in a magiclink being sent out.
```json
{
"email": "[email protected]",
"password": "new-password",
"phone": "+123456789",
"data": {
"key": "value",
"number": 10,
"admin": false
}
}
```
Returns:
```json
{
"id": "11111111-2222-3333-4444-5555555555555",
"email": "[email protected]",
"email_change_sent_at": "2016-05-15T20:49:40.882805774-07:00",
"phone": "+123456789",
"phone_change_sent_at": "2016-05-15T20:49:40.882805774-07:00",
"created_at": "2016-05-15T19:53:12.368652374-07:00",
"updated_at": "2016-05-15T19:53:12.368652374-07:00"
}
```
If `GOTRUE_SECURITY_UPDATE_PASSWORD_REQUIRE_REAUTHENTICATION` is enabled, the user will need to reauthenticate first.
```json
{
"password": "new-password",
"nonce": "123456"
}
```
### **GET /reauthenticate**
Sends a nonce to the user's email (preferred) or phone. This endpoint requires the user to be logged in / authenticated first. The user needs to have either an email or phone number for the nonce to be sent successfully.
```json
headers: {
"Authorization" : "Bearer eyJhbGciOiJI...M3A90LCkxxtX9oNP9KZO"
}
```
### **POST /logout**
Logout a user (Requires authentication).
This will revoke all refresh tokens for the user. Remember that the JWT tokens
will still be valid for stateless auth until they expires.
### **GET /authorize**
Get access_token from external oauth provider
query params:
```
provider=apple | azure | bitbucket | discord | facebook | figma | github | gitlab | google | keycloak | linkedin | notion | slack | spotify | twitch | twitter | workos
scopes=
```
Redirects to provider and then to `/callback`
For apple specific setup see:
### **GET /callback**
External provider should redirect to here
Redirects to `#access_token=&refresh_token=&provider_token=&expires_in=3600&provider=`
If additional scopes were requested then `provider_token` will be populated, you can use this to fetch additional data from the provider or interact with their services
