Authentication, Authorisation & Trust

What is the difference between Flask-Login style sessions and JWT-based API auth?

← Back to all FAQ
By NHI Mgmt Group Editorial Team Updated June 7, 2026 Domain: Authentication, Authorisation & Trust

Session-based authentication is stateful and fits browser logins, while JWT-based authentication is stateless and fits API calls and service-to-service use. The key difference is governance: sessions are easier to revoke centrally, while JWTs shift more responsibility to token lifetime, storage, and blacklist design.
