The Unisys Stealth(identity) uAuthenticator mobile application is used by end users to enroll and authenticate bio-metric based identity information in conjunction with our Stealth(identity) Software as a Service (SaaS) Product. The application communicates with the back-end services through published, secure APIs to enroll and authenticate user information, including facial images. The application is being made available, for free, but the app will only work for end-users that have an appropriate Customer ID that is given to customers that have been vetted via approved Unisys processes and on-boarded for our SaaS Product.
Authenticator+

Authenticator+ is no longer actively maintained. We've built its successor: Keylet — 2FA Authenticator. Same makers, everything you're used to, but faster, fully private (nothing leaves your device), with passkey support and NO ads. Import your existing codes in one tap. Search "Keylet" on the App Store to make the switch.
