OAuth 2.0 helps secure modern applications, but token misuse remains a key security risk. That’s where token revocation comes in. This guide walks you through how OAuth 2.0 token revocation works, when to use it, and how to implement it using real examples — including Java code and ForgeRock configuration insights. Why Token Revocation Matters Access tokens and refresh tokens give clients access to protected resources — but what if: ...
