What common mistake do developers make with Token revocation, why does the mistake cause problems, and what is the safer approach? One recurring problem with token revocation is applying it without understanding the boundary it protects. Treating possession of any valid API token as permission to access every resource in the system. In addition, Applications can revoke tokens when a device or client should no longer have access. Safer engineering approach: keep the responsibility in the correct layer, use the framework's supported API, validate and authorize inputs, avoid hidden side effects, and verify the behavior with tests.
