OneAuth is a free industry-standard multi-factor authentication (MFA) app developed by Zoho for securing your Zoho accounts and social accounts such as Google, Facebook, and Twitter. Configuring MFA for your online accounts will increase the security, thereby reducing the risk of a breach or experiencing any unauthorized access to your accounts. OneAuth is available in iOS, Android, and Windows platforms.

Zoho OneAuth's passwordless sign-in will come in handy if you have to sign in to your Zoho account more often. Passwordless sign-in is 100% safer and faster than password-based MFA.

OneAuth provides you a true single sign-on (SSO) experience, if you have multiple Zoho applications on your mobile device. Once OneAuth is configured for your account, you don't have to enter your credentials to sign in when you install a new Zoho mobile app.

Secure your other online accounts such as Google, Facebook, Instagram, Twitter, and Microsoft via OneAuth's inbuilt One-time Passcode (OTP) authenticator. You can also use the OTP authenticator as a guest user without signing in or creating a Zoho account. However, to back up and sync your TFA secrets you will need to sign in to your Zoho account.

OneAuth comes up with a revamped backup and recovery systems. A passphrase can be used to recover your OneAuth app if you lose your device or uninstall the app.

Zoho OneAuth supports using multiple accounts for authentication simultaneously. Set up and secure your business and personal Zoho accounts with MFA using OneAuth.

Sign in to your OneAuth app on multiple devices and mark them as primary and secondary devices. Secondary devices will be helpful if you lose or cannot use your primary device for authentication like during a travel.
