Hi @Raja R
The access tokens in the ms graph API are not associated, and the invalidation of one token will not cause the invalidation of another token. The invalidate of the access token is only related to its lifetime, and the default lifetime is 1 hour. Note that even if the user logs out the application, the access token will not invalidate immediately, it can still call the graph api and will expire automatically after 1 hour.
