Ente Auth vs RSA Authenticator (SecurID)

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.

RSA Authenticator (SecurID) is an authentication system for organizations securing on-premises environments and supporting access to cloud and on-premises applications. It offers hardware and software authenticators, including OTP, MFA, and passwordless options. The mobile app supports push notifications, device biometrics, FIDO, and OTP for applications such as VPNs and Microsoft 365. RSA Authentication Manager provides authentication, access, and management capabilities and can be deployed on a hardened rack-mountable appliance. RSA describes its hybrid approach as intended to maintain access during network disruptions or cloud outages. Integration paths include SAML, RADIUS, and authentication APIs, with named integrations such as Okta and SailPoint. The mobile app can manage up to 30 credentials, but they cannot be backed up or restored; device-bound passkeys also cannot be exported or restored. Version 4.7 requires Android 10.0 or later or iOS 16.0 or later. RSA states that it uses FIPS 140-2 or FIPS 140-3 validated cryptographic modules for data at rest and in motion across mobile apps, cloud, and on-premises.
