Q.
What is my BOOK☆WALKER “Sign-in ID”?
Your e-mail address or your external account ID is your “Sign-in ID”.
It is possible to create a BOOK☆WALKER account by registering with an email address or an external account.
Email address account
Your email address is your Sign in ID.
External account
Your external account ID (Google/X (formerly Twitter)/Facebook/Apple/niconico) is your Sign in ID.
How to sign in
1. Click the [Sign in] button on the top right corner
2. Sign in with either your registered email address or external account
Notes
Please make sure to only sign with your external account if your either already created a BOOK☆WALKER account with your external account or already linked email address account to your external account, because otherwise you will end up creating a new account.
Please refrain from making multiple accounts, as we are not able to merge accounts together.
