> Microsoft OAuth2 strategy for Überauth.

Quick start blog post: [Authenticating users with Microsoft OAuth](https://www.stuartwelham.com/articles/authenticating-users-with-microsoft-oauth)

## Installation

1. Register an application in the Azure Portal ([see Microsoft tutorial for more info](https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app)).

2. Add `:ueberauth_microsoft` to your list of dependencies in `mix.exs`:

```elixir
def deps do
[
{:ueberauth_microsoft, "~> 0.23"}
]
end
```

3. Add the strategy to your applications:

```elixir
def application do
[
applications: [:ueberauth_microsoft]
]
end
```

4. Add Microsoft to your Überauth configuration:

```elixir
config :ueberauth, Ueberauth,
providers: [
microsoft: {Ueberauth.Strategy.Microsoft, []}
]
```

5. Update your provider configuration:

```elixir
config :ueberauth, Ueberauth.Strategy.Microsoft.OAuth,
client_id: System.get_env("MICROSOFT_CLIENT_ID"),
client_secret: System.get_env("MICROSOFT_CLIENT_SECRET")
```

6. Include the Überauth plug in your controller:

```elixir
defmodule MyApp.AuthController do
use MyApp.Web, :controller
plug Ueberauth
...
end
```

7. Create the request and callback routes if you haven't already:

```elixir
scope "/auth", MyApp do
pipe_through :browser

get "/:provider", AuthController, :request
get "/:provider/callback", AuthController, :callback
end
```

8. Your controller needs to implement callbacks to deal with `Ueberauth.Auth`
and `Ueberauth.Failure` responses.

For an example implementation see the [Überauth Example](https://github.com/ueberauth/ueberauth_example) application.

## Single Tenancy

If you are going to use your app only internally you may need to configure it for a single tenant.
To do so you only need to add `tenant_id` to your provider configuration like:

```elixir
config :ueberauth, Ueberauth.Strategy.Microsoft.OAuth,
tenant_id: System.get_env("MICROSOFT_TENANT_ID"),
client_id: System.get_env("MICROSOFT_CLIENT_ID"),
client_secret: System.get_env("MICROSOFT_CLIENT_SECRET")
```

## Calling

Depending on the configured url you can initial the request through:

/auth/microsoft

By default the scopes used are:

- openid
- email
- offline_access
- https://graph.microsoft.com/user.read

_Note: at least one service scope is required in order for a token to be
returned by the Microsoft endpoint_

You can configure additional scopes to be used by passing the `extra_scopes`
option into the provider:

```elixir
config :ueberauth, Ueberauth,
providers: [
microsoft: {
Ueberauth.Strategy.Microsoft,
[extra_scopes: "https://graph.microsoft.com/calendars.read"]
}
]
```

If you would like users to have the option to choose an alternate account to authenticate with instead of defaulting to the logged in account, you may pass the `prompt` option in to the provider (per [Microsoft documentation](https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow)):

```elixir
config :ueberauth, Ueberauth,
providers: [
microsoft: {Ueberauth.Strategy.Microsoft, [prompt: "select_account"]}
]
```
