When a token is used, its Hash is rotated, but the ID remains the same.\n\nIf an attacker steals a user's Remember-Me token and uses it to authenticate, the attacker is issued a new rotated token (same ID, new Hash). When the legitimate user later attempts to use their original token, Gitea correctly detects a hash mismatch for the given ID.\n\nAccording to the referenced Paragonie specification, this indicates a compromised token, and ALL active remember-me sessions for that user MUST be invalidated.
