Authy vs Ente Auth

Authy is a free two-factor authentication app for Android and iOS that generates TOTP codes for online accounts. Users can scan QR codes from services including Facebook, Amazon, Google, Microsoft and Dropbox, then access tokens on a phone, tablet or Apple Watch. Codes are generated on the device, so a phone does not need an internet connection to access secured websites. Authy supports encrypted backups and synchronization across multiple devices. Access to tokens can be protected with Touch ID, a PIN or a password. New devices can be added through SMS, voice or approval from an existing device; users can also rename or remove lost or stolen devices and disable future app installations. Authy says it encrypts authentication data and cloud backups without retaining users’ backup passwords. That means a forgotten backup password cannot be recovered through Authy. Its listed free plan costs nothing and includes two-factor authentication, encrypted cloud backup and multi-device support.

Ente Auth is a free authenticator for storing TOTP and HOTP two-factor codes. It is available on Android, iOS, Linux, macOS, Windows, and web, with encrypted sync across mobile, desktop, and web devices. Account users can use end-to-end encrypted cloud backups; the maker says the cryptography has been externally audited. Ente Auth is open source and supports importing and exporting codes. Native imports are listed for 2FAS Authenticator, Aegis, andOTP, Bitwarden, Google Authenticator, LastPass, Proton, and Raivo OTP. Codes can be organized with search, tags, pins, notes, multi-select, and custom sorting, or shared through links that expire after 2, 5, or 10 minutes. Exports include plain text, encrypted files, and HTML QR codes compatible with Google Authenticator. The app can be used without an account, but those codes remain on the device and are not synced or backed up to Ente. App lock can use a device lock, PIN, or password; it protects the interface, not by re-encrypting Auth data.
