There are two possibilities for logging into a new wallet address.
1. Sometimes confusion arises when a user creates an account with email, expecting it to automatically connect to the same address as their phone number login. We only associate email and phone numbers to the same address if a user explicitly signs up with a phone number first, then adds the email address as a backup.

2. If you exported your private key completely out of Fortmatic, the next time you log in, you’ll be generated a new wallet address.
