Sample Answer
On my last project, we migrated from cookie sessions to a JWT-based auth flow for a mobile-heavy app with ~2M MAUs. We issued short-lived access tokens (15 minutes) and longer-lived refresh tokens (7–14 days), both signed with rotating keys managed in KMS. Access tokens never hit storage; refresh tokens were stored hashed in a DB/Redis so we could revoke individually. The flow was: login → issue access + refresh → clients send access token in the Authorization header (no JWTs in localStorage) → when it expires, hit a dedicated refresh endpoint guarded by rate limiting and device fingerprint checks. We implemented role- and permission-based authorization at the API gateway and in service-level middleware, so sensitive endpoints required both scopes and contextual checks (e.g., resource ownership). We also added a token blacklist for high-risk events (password change, device loss) and saw unauthorized access incidents drop by ~80% after the rollout.
