Tokens now carry a keyed hash of the account's security stamp, and every authenticated request compares it with the stored stamp (cached for 60 s, evicted in-process on change). A password reset or change, a deactivation and a deletion all rotate or remove the stamp, so tokens issued before them get 401. Tokens without the claim get 401 too.
