If you know the e-mail address that you used to register/login to your existing BookWalker Global account, then you can migrate your account simply by performing a normal login.
The authentication dialog will guide you thought receiving a verification code and setting a new password for your account:
If no account is found, then it’s possible that you used another e-mail address on your BookWalker Global account, or you were using SSO (login with Google, Apple etc.).
If so, please go to the migration code instructions instead.
Why can’t I see my Coins / eBooks after migration?
