Password Protection

Optionally lock your codes behind a password. They are encrypted on your device, and a recovery code means a forgotten password never costs you your accounts.

Turn it on in the extension's settings, under “Password protection” — you get a recovery code to save.

Time-Synced Codes

Built-in time synchronization check ensures your codes are always accurate and valid.

QR Code Scanner

Scan QR codes directly from your screen. No need for a phone camera — just click and add.

Offline Ready

Works completely offline. No internet connection required to generate your 2FA codes.

Frequently Asked Questions

Is my data secure?

Your accounts live only on your device. We have no servers and never receive your data.

  • Secret keys never leave your device
  • Automatic local backups (last 7) in case something goes wrong
  • Stored in Chrome storage, with sync as an optional second copy

By default your codes are stored unencrypted and are protected by your computer login and Chrome profile — the same as most authenticator extensions. For stronger protection, turn on password protection in Settings: your codes are then encrypted on your device, including the backups, and cannot be read without your password.

Can I use this on multiple devices?

Yes! If you enable Chrome Sync:

  • Your accounts will sync across all your Chrome browsers
  • You can also manually export and import on different devices
  • Note: Local storage is also used as a backup
Can I import from Google Authenticator?

Yes! Google Authenticator has an export feature:

  • Open Google Authenticator app
  • Tap "Transfer accounts" → "Export accounts"
  • Select accounts to export
  • Take a screenshot of the QR code
  • In this app: Add Account → QR Code → upload the screenshot

If you already have the transfer link as text — it starts with otpauth-migration:// — skip the screenshot and paste it into Settings → "Paste links" instead.

Why are my codes not working?

If codes are rejected, the most common reason is time synchronization:

  • Your computer clock must be accurate (within 30 seconds)
  • TOTP codes are time-based and expire every 30 seconds
  • Check if you see a time warning at the top of the app
  • Fix: Update your system time or enable automatic time sync
