FastAPI Users database adapter for SQLAlchemy
Decision gist · record as of 2026-08-14
Yes, if you are building a FastAPI application and need user authentication with SQLAlchemy. The package has low install friction, no known vulnerabilities, and a permissive license. However, the 587-day release gap and dormant maintenance status mean you should verify compatibility with your specific versions of fastapi-users and sqlalchemy before committing to production use.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; assumes an existing FastAPI application and SQLAlchemy async session setup.
- Low friction installation with only two runtime dependencies (fastapi-users and sqlalchemy).
- Maintenance is dormant—no releases in 587 days—but the package is marked Production/Stable and the repository remains active with a recent commit on 2025-01-04.

What it is and what it does
This package is a database adapter that bridges FastAPI Users (a user management library) with SQLAlchemy ORM, allowing you to persist user data in a relational database. It handles the integration between FastAPI Users' authentication logic and your SQLAlchemy models, so you don't have to write the adapter yourself.
You use it by installing it alongside fastapi-users and sqlalchemy, then instantiating its database class with your SQLAlchemy session and user model. It's designed to work with FastAPI's async patterns and supports modern Python versions (3.9–3.13). The package is marked Production/Stable but has not been released in over a year, so while it appears complete for its scope, you should verify it still works with your target versions of its dependencies.
Use it for
- Add a complete user registration and login system to a FastAPI app backed by a SQL database without writing authentication code from scratch.
- Integrate FastAPI Users with an existing SQLAlchemy schema to add user management to a legacy or new async FastAPI project.
- Build a multi-tenant or role-based access control system by extending FastAPI Users' user model through SQLAlchemy ORM.
- Quickly prototype a FastAPI service with built-in user authentication and session management using SQLAlchemy as the persistence layer.
