OpenOTP Authentication Server vs Zoho OneAuth

OpenOTP Authentication Server has no write-up on Specifiction yet; its figures are above.

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.
