Reactivating a Matrix Account
Reactivating your Matrix Account
Once your account has been deactivated, it is impossible to reactivate it again or reuse the username. Your user is stored indefinitely to avoid account recycling. To protect the security and privacy of our users, we never reactivate, or release deleted usernames. Instead, we recommend creating a new account using a different Matrix ID.
