All your two-factor authentication codes in one app. Scan a QR code once, and the app keeps generating the 6-digit sign-in code you need — for Google, Facebook, Instagram, Binance, Microsoft, PayPal and 2,500+ other services that support 2FA.

This app is that second step, and it lives on your phone. HOW IT WORKS 1. Open the 2FA settings of any website or app and show the QR code. 2. Scan it with the app, or type the setup key by hand. 3. Sign in with the 6-digit code the app shows. A new code appears every 30 seconds. WHAT YOU GET • One-time codes (TOTP) for 2,500+ services • QR code scanner and manual key entry • Codes refresh every 30 seconds, countdown ring on every entry • Works fully offline — no network, no cellular, no account required • Copy a code with one tap • Search across your accounts • Reorder and rename entries the way you want ALSO INCLUDED Your subscription covers more than codes: • Ad blocker for Safari — fewer ads, no cookie banners, no tracking scripts • Wi-Fi security scan — see every device on the network and whether it is safe to connect • Private browser — browse without leaving a trail PRIVACY Your keys stay on your device.
