Tik Tok login device management will not update the login time without switching accounts, but only when switching accounts.

The login mechanism of Tik Tok is an authorized login system based on OAuth2.0 protocol. When a user logs in with Tik Tok, Tik Tok will generate a temporary calling certificate (code) and redirect the user to the callback interface of the third-party application. Third-party applications can exchange this authorization code for access (token), through which users' basic open information and other authorization related information can be obtained.
