ROSTR supports two ways to log in: ROSTR login (email address and phone number) or Google Sign-In (Google account).
If you're seeing a message that your phone number is tied to another account, it's often because you're signing in with a different method than the one you originally used to sign up. Try switching methods and see if that resolves it.
If you're stuck on the phone verification screen, visit https://www.rostr.cc/clearsession and then try signing in again.
Still seeing the error? If you don't believe you have another account linked to this number, reach out to us at [email protected] and include the phone number you're trying to use and the email address you signed up with. We'll look into it and get you sorted.
