When a user changes their password, the existing list of Access Tokens stay valid instead of expiring. If a user finds that their account has been compromised, they can update their password. In versions up to and including 0.18.1, though, the bad actor will still have access to their account because the bad actor\u0027s Access Token stays on the list as a valid token. The user will have to manually delete the bad actor\u0027s Access Token to secure their account. The list of Access Tokens has a generic Description which makes it hard to pinpoint a bad actor in a list of Access Tokens. A known patched version of Memos isn\u0027t available. To improve Memos security, all Access Tokens will need to be revoked when a user changes their password. This removes the session for all the user\u0027s devices and prompts the user to log in again. One can treat the old Access Tokens as \"invalid\" because those Access Tokens were created with the older password."
