Protect and sync your progress

Your progress is saved in this browser. Create an account only if you want backup or sync across devices.

Create account

Email verification is required before cloud sync starts.

Passkeys can be added after email verification from Account Settings.

Browser passkey checks start only after you choose this control.

Password registration requires email verification before server sync starts. Password reset and verification messages are account security email, separate from learning reminders or product updates.

Local-first boundary

Guest learning remains available, and account failures do not damage local progress.

Passkey ready

Passkeys are configured on the server and can be used for sign-in or added from Account Settings after email verification.
