Authenticator App - OneAuth

Authenticator App - OneAuth is a trusted two-factor authentication app that secures your online accounts with industry-standard encryption and ease of use. Over 1 million users rely on OneAuth to protect their accounts across Twitter, Facebook, LinkedIn, and thousands of other services.

Take control of your account security with time-based one-time passwords that work even when you're offline. Adding accounts is simple—just scan a QR code or enter details manually. Once set up, you'll authenticate your accounts in seconds using OneAuth's streamlined interface. Whether you're signing into social media, email, or work platforms, two-factor authentication provides the additional layer of protection passwords alone cannot offer.

Your backup and recovery are entirely in your hands. OneAuth encrypts all your OTP secrets and stores them securely, recoverable only with a passphrase known exclusively to you. If you lose or replace your device, you regain access without relying on anyone else. The app syncs your authentication secrets across all your devices, so you can generate OTPs from your phone, tablet, or Wear OS smartwatch—access your accounts from anywhere without compromise.

Stay organized and efficient with built-in features designed for real-world use. Create separate folders for personal and work accounts, then reorder them however you prefer. Brand logos appear next to each account for instant visual recognition. Need to find a specific account quickly? OneAuth's search function gets you there in moments. Even new users can explore the full app without creating an account, with options to export and import credentials when switching devices. Migrating from Google Authenticator takes just a few taps.

For Zoho account holders, OneAuth offers enhanced multi-factor authentication options. Enable passwordless sign-in using push notifications to your phone or Wear OS device, scan QR codes, or fall back to time-based OTPs offline. Add biometric authentication—fingerprint or face recognition—to ensure only you can access your accounts. Monitor all your connected devices and sessions, track login locations, and designate which devices are primary or secondary for your security.

Experience the app your way with dark mode to reduce eye strain and app shortcuts to reach key functions directly from your home screen. Authenticator App - OneAuth is completely free, always will be, because Zoho believes every person deserves secure, private access to the internet. Our support team is available 24/7 to help.
