Implement OAuth2 Password Flow in FastAPI
Tests FastAPI security integration and stateless auth patterns. A strong answer covers the POST /token endpoint returning a JWT, the OAuth2PasswordBearer dependency, and get_current_user decoding the JWT sub.
Tests deep familiarity with FastAPI's security primitives and stateless auth design. A strong answer walks through three layers: first, a POST /token endpoint accepting OAuth2PasswordRequestForm, verifying the hashed password with pwdlib, and returning a JWT access_token with a subject claim; second, an OAuth2PasswordBearer dependency extracting the Bearer token from the Authorization header; third, a get_current_user dependency decoding the JWT, validating the sub claim, and injecting the user into path operations.
