tokenkeeper-api 0.0.2

A minimal FastAPI service for creating, verifying, and revoking user-scoped API tokens. Uses Argon2 hashing and PostgreSQL for secure token management.

TokenKeeper API

TokenKeeper is a secure, FastAPI-based service for managing and verifying personal access tokens. It integrates with AWS Cognito for user authentication and uses PostgreSQL for persistent storage. Tokens are hashed with Argon2 and optionally support expiration, revocation, and last-used tracking.

Features

• 🔐 Secure token generation using Argon2 hashing
• 📅 Optional token expiration and usage tracking
• ✅ Verification and revocation of tokens
• 🧾 List non-revoked, non-expired tokens
• 🪪 Cognito-based user authentication
• 🗃️ PostgreSQL + SQLAlchemy (async) backend

API Endpoints

• POST /token — Create a new token
• POST /token/verify — Verify token validity
• POST /token/revoke — Revoke a token by name
• GET /token — List current user’s active tokens

Requirements

• Python 3.12+
• PostgreSQL
• AWS Cognito User Pool
• asyncpg, sqlalchemy, fastapi, passlib[argon2], cognito-jwt-verifier

Getting Started

1. Update your database URL in db.py:

DATABASE_URL = "postgresql+asyncpg://user:password@localhost/tokenkeeper"

2. Set up your Cognito issuer and client ID in auth.py:

ISSUER = "https://cognito-idp.<region>.amazonaws.com/<user_pool_id>"
CLIENT_IDS = ["<app_client_id>"]

3. Run the FastAPI app:

uvicorn tokenkeeper.main:app --reload
