RSA Authenticator (SecurID) vs Yubico Authenticator

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.

Yubico Authenticator generates two-step verification codes for online accounts on mobile and desktop devices. It supports TOTP and HOTP, and users can add credentials by scanning a service’s QR code. Credentials are stored in a YubiKey secure element; Yubico says they cannot be extracted. Since the credentials remain on the portable YubiKey, the same codes are available through the mobile and desktop apps. The mobile app supports tap-and-go authentication on NFC-enabled devices, and credentials can be added with a YubiKey touch or NFC tap. Yubico says users can unlock a YubiKey with Face ID or Touch ID. The app can display OATH codes and manage a YubiKey’s FIDO PIN or perform a factory reset. It is free and open-source software, listed at free, for Windows, macOS, Linux, iOS/iPadOS, and Android. Generating and displaying OATH credentials with the desktop app requires a YubiKey.
