Duo Mobile vs Zoho OneAuth

Duo Mobile provides two-factor and multi-factor authentication for company and personal data on iOS and Android phones and tablets. Users can approve or deny sign-ins with Duo Push, or enter time-based passcodes generated by the app. It also supports third-party TOTP accounts, biometrics, and passcodes. Duo Restore backs up and restores Duo-protected accounts when a user changes devices, and Security Checkup provides a mobile-device security score through app notifications. For organizations, Duo connects with legacy infrastructure, custom apps, VPNs, SaaS tools, and offline devices. Integration methods include RADIUS, SAML/OIDC, Duo Authentication Proxy, and direct API connections. Adaptive policies can consider user role, location, application, network, and device health. Duo says it keeps private keys on users’ devices in a tamper-proof secure element and does not store passwords. The free plan covers 10 users; paid plans start at $3.00 per month, and a 30-day trial is listed. End users needing enrollment or troubleshooting help are directed to their organization’s Duo administrator.

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.
