Once account is registered, there is no option to change your login method.
However, if you lost access to your account or moved to a phone with a different operating system and need help, you can contact us via in-game Customer Support or by sending a message to the e-mail address: firstname.lastname@example.org
The migration process from previous account to the new one may take several days, so please be patient.
Caution: Always remember about the login method you have chosen, your login and password. We don’t store that data in our database!
