An authenticator code, a password reset link and an email change link can each be used once, even if two requests arrive at the same moment. Resetting your password or turning off two-step sign-in now sends a notice to your address, and in a Kemble Work workspace the change is recorded for administrators.
Webhooks, app interactions and single sign-on connect only to the address Kemble checked, so a name that changes its answer in between cannot redirect them. When a workspace administrator, a directory or a guest’s end date takes someone out of a workspace, their other open tabs drop it right away.
