The VivoKey Flex One is an implantable cryptobionic smart card platform for running identity, security, cryptography, and payment applications. One such application is the VivoKey OTP applet, which allows you to store and generate OTP two-factor codes in vivo. Both time based TOTP and counter based HOTP credentials are supported. VivoKey Authenticator is the Android app that interacts with the VivoKey OTP applet running on your VivoKey Flex implant.

Storing credentials and generating authentication tokens in your VivoKey Flex ensures that your credentials can never be forgotten, lost, or stolen, and remain safe even if your phone is lost or compromised. Furthermore, you can use any Android device to request your OTP credentials from VivoKey Flex without sharing those credentials with the Android device or it's owner. Authentication credentials are generated inside your VivoKey Flex, and source keys are never sent to or seen by the phone.

Authentication credential generation can also be protected by an optional password, ensuring nobody can sneak up on you and request authentication tokens without your knowledge.
