Zoho OneAuth
Free multi-factor authentication app for Zoho and third-party accounts with backup and multi-device sync.
About Zoho OneAuth
Zoho OneAuth is a free multi-factor authentication (MFA) app. It generates time-based one-time codes on the user's own device, which can be used as a second step when signing in to Zoho accounts and to third-party accounts such as Google, Adobe, GitHub, Zoom, X, Instagram, and LinkedIn. The homepage states that it is available on Apple, Android, and Windows devices, and the directory lists Mac and web as well.
The app also covers passwordless sign-in with a QR code, mobile single sign-on to Zoho apps, and organization-wide MFA set up by IT administrators through Zoho Directory. Account recovery after device loss relies on a passphrase, and the homepage says the passphrase also helps sync OTP codes across devices. The homepage does not say where backup or sync data is stored, and it does not list which features are included in each plan.

Zoho OneAuth FAQ
Why use an authenticator app instead of SMS-based login?
The homepage states that an authenticator app involves an external device, which gives greater security during login. It says this approach avoids SIM swap attacks and SMS-based phishing. It does not guarantee protection against all attacks.
What is a passphrase and why is it important?
A passphrase is a set of characters used to speed up recovery and regain access to a Zoho OneAuth account after device loss, formatting, or app uninstallation. The homepage also says it helps sync OTP codes across devices.
Is Zoho OneAuth free to use?
The homepage states that Zoho OneAuth is available for free across platforms. It can be used to enable MFA for Zoho work accounts and to secure personal online accounts.
