About this app

Protect your online accounts with Authenticator – a simple, fast and secure two-factor authentication (2FA) app that generates one-time verification codes right on your phone.

Hackers only need your password to break into an account. With 2-step verification enabled, they also need a 6-digit code that changes every 30 seconds – and that code lives only on your device. Authenticator makes adding this extra layer of security effortless.

• Generate time-based one-time passwords (TOTP) for all your accounts
• Add accounts in seconds by scanning a QR code
• Works 100% offline – no internet needed to get your codes
• Your secret keys are stored locally on your device, never sent to our servers
• Clean, modern and easy-to-use interface

📷 ADD ACCOUNTS YOUR WAY
• Scan QR Code – point your camera at the 2FA QR code on any website
• Import from Photos – scan a QR code from a screenshot or image in your gallery
• Enter Manually – type in the website name, account and secret key

⚡ FAST & CONVENIENT
