Help & Support

Developer & operator: 宋鑫玮

Getting started & offline use

Create a master password of at least 12 characters, then add accounts or authenticators. No online registration is needed. Vault, generation and code calculation work offline. System AutoFill, passkeys and cloud sync are not supported yet. Keep an encrypted backup and remember your master password.

Codes are rejected

Enable automatic date/time and check your service’s period, algorithm and digits. Scanning preserves QR parameters; an omitted period defaults to 30 seconds. Accounts forced to 60 seconds by older versions need checking. Do not delete active authenticators or send their setup keys to support.

Biometrics & forgotten passwords

Use the master-password option if biometrics are cancelled, locked or invalidated by enrollment changes. Back up while you can unlock. The developer cannot reset your master password. Restoring a backup requires that backup’s master password; biometrics cannot replace it.

Backup, migration & restore

Copy an encrypted backup in Settings and save it safely. Restoring replaces the current vault, so back it up first. Make a new backup after changing the master password; old backups still use the old password. Verify a backup before uninstalling or clearing app data.

Scanning & camera access

Allow camera access to scan a service’s otpauth://totp QR. You can select a photo or enter the setup key manually. HOTP and Google Authenticator batch-transfer QR codes are not supported; use the service’s single-account setup QR.

Deleting data & getting help

Delete passwords in their detail page and authenticators from their menu; confirmation is required. Local deletion does not disable the service’s two-factor authentication. For help, send app/OS versions, reproduction steps and non-sensitive errors, never vault contents.
