API Authentication: Unhappy Paths
API Authentication: Unhappy paths. Authentication testing usually focuses on the happy path: valid credentials, expected flows, successful responses. But production environments surface the unhappy paths — expired tokens, invalid grants, certificate mismatches, and edge cases that were never tested.
API Authentication: Unhappy paths
Authentication testing usually focuses on the happy path: valid credentials, expected flows, successful responses. But production environments surface the unhappy paths — expired tokens, invalid grants, certificate mismatches, and edge cases that were never tested. This video explores the authentication failure modes that matter most in production, how they manifest for consumers, and how active monitoring helps teams catch auth problems before they escalate into incidents.
