Authtify
Read full descriptionHide full description
Authtify is an identity validator that can receive verification requests online and verify whether they are approved or rejected. Use Authtify authentication, send verification requests online, verify in real time, and protect the security of your account data information. Based on OTP technology, when users perform authentication, Authtify authentication is triggered in a third-party application. After logging into Authtify with an account and password, real-time online authentication requests are initiated. Authtify users can directly click pass or reject, enter the set PIN code, and complete Authtify authentication. Authtify validation supports biological validation methods to pass validation. Users can enable biometric authentication in the account and security settings of the Authtify application. When receiving real-time authentication requests, Authtify users can authenticate through the biometric authentication method set by the device, recognize through Face ID and Touch ID, and ensure that only you have access to the application, ensuring your data privacy and operational security. Authtify supports blacklisting verification applications and application verification accounts. After blacklisting, applications will be placed on a blacklist, and accounts under subsequent applications will not be allowed to undergo Authtify verification. Once the blacklisting is lifted, verification can resume normal use. A simple and intuitive interface makes it easy for users to use, and provides home page shortcut application customization settings, making it convenient for users to operate quickly.
