SAP Authenticator vs Zoho OneAuth

SAP Authenticator is a free mobile app that generates time-based passcodes for systems requiring one-time password authentication. Each code works for one login attempt, and the app creates a new one every 30 seconds. A passcode can act as a second factor or as an alternative password. The app supports multiple accounts, which can be configured by scanning a QR code or entering a secret key. Online account setup is also available only with SAP Authenticator. For accounts set up online, administrators add applications; users cannot maintain those applications themselves. Users can save applications in the app and access them later through mobile single sign-on without another authentication step. SAP documentation describes OTP authentication and mobile SSO use with SAP Single Sign-On and SAP Fiori Client. The app runs on iOS and Android and can be protected with a password. SAP recommends protecting the app with a logon password and using two-factor authentication when the scenario allows it.

Zoho OneAuth is a free authenticator for Zoho work accounts and personal online accounts. It supports time-based one-time passwords, push approvals, and QR-code login; Zoho accounts can also use passwordless sign-in. For organizations, Zoho Directory lets IT administrators configure multifactor authentication across employees’ Zoho accounts. OneAuth also supports third-party accounts such as Google, Adobe, Github, Zoom, X, Instagram, and LinkedIn.

A passphrase can help restore access after a device is lost or reset, or the app is removed, and can synchronize OTP codes across devices. Encrypted backup and multi-device sync are supported. Biometrics can unlock the app, while remote logout removes unwanted sessions. A sign-in restriction can block future logins to a Zoho account until disabled. The app is available for Android, iOS, Windows, and macOS, and supports phones, tablets, laptops, smart watches, and desktops. Its listed free plan includes time-based OTP authentication, backup and recovery, multi-device support, and passwordless Zoho sign-in.
