To change the email address, contact customer support. Please note: we cannot change your account email if your initial registration/login takes place via Google.
If your initial registration took place through a phone number - this is your only way to log in, even if you have an email in your account - you must use the phone number to log into your account.
Important
If you do not have access to a phone number or have difficulty logging in using this method, please contact support.
If none of the methods of changing email or phone number helped, delete the old account and register a new one, first contacting customer support to prepare for the account migration process (verification is required).
