# FastAPI SSO
[](https://codecov.io/gh/tomasvotava/fastapi-sso)
FastAPI plugin to enable SSO to most common providers (such as Facebook login, Google login and login via
Microsoft Office 365 account).
This allows you to implement the famous `Login with Google/Facebook/Microsoft` buttons functionality on your
backend very easily.
**Documentation**: [https://tomasvotava.github.io/fastapi-sso/](https://tomasvotava.github.io/fastapi-sso/)
**Source Code**: [https://github.com/tomasvotava/fastapi-sso](https://github.com/tomasvotava/fastapi-sso/)
## Demo site
An awesome demo site was created and is maintained by even awesomer
[Chris Karvouniaris (@chrisK824)](https://github.com/chrisK824). Chris has also posted multiple
Medium articles about FastAPI and FastAPI SSO.
Be sure to see his tutorials, follow him and show him some appreciation!
Please see his [announcement](https://github.com/tomasvotava/fastapi-sso/discussions/150) with all the links.

## Security Notice
### Version `0.16.0` Update: Race Condition Bug Fix & Context Manager Change
A race condition bug in the login flow that could, in rare cases, allow one user
to assume the identity of another due to concurrent login requests was recently discovered
by [@parikls](https://github.com/parikls).
This issue was reported in [#186](https://github.com/tomasvotava/fastapi-sso/issues/186) and has been resolved
in version `0.16.0`.
**Details of the Fix:**
The bug was mitigated by introducing an async lock mechanism that ensures only one user can attempt the login
process at any given time. This prevents race conditions that could lead to unintended user identity crossover.
**Important Change:**
To fully support this fix, **users must now use the SSO instance within an `async with`
context manager**. This adjustment is necessary for proper handling of asynchronous operations.
The synchronous `with` context manager is now deprecated and will produce a warning.
It will be removed in future versions to ensure best practices for async handling.
**Impact:**
This bug could potentially affect deployments with high concurrency or scenarios where multiple users initiate
login requests simultaneously. To prevent potential issues and deprecation warnings, **update to
version `0.16.0` or later and modify your code to use the async with context**.
Code Example Update:
```python
# Before (deprecated)
with sso:
openid = await sso.verify_and_process(request)
# After (recommended)
async with sso:
openid = await sso.verify_and_process(request)
```
