The ID.me Authenticator app serves as a TOTP (Time-Based One-Time Password) code generator, which enhances the security of your account login process. To sign in, users need to provide their username, password, and a verification code generated by the app. Once the app is configured and linked to your account through scanning a QR code, it can generate these verification codes independently of any network or cellular service, ensuring consistent and secure two-factor authentication.
This functionality allows users to authenticate securely even when they do not have internet access or cellular connectivity, making it highly reliable for various situations. The app simplifies the process by storing the necessary secret keys securely after initial setup, enabling quick generation of verification codes at any time. This feature is especially useful for users who need a dependable method of authentication without relying on external devices or services.
In addition to TOTP code generation, the ID.me Authenticator also supports push-based authentication. This method improves convenience by allowing users to approve login requests directly through a push notification sent to their mobile device. After entering their username and password, users receive a prompt on their phone to verify their login attempt, streamlining the process and eliminating the need to manually enter verification codes.
To enable the push-based authentication feature, users must enroll and connect their ID.me Authenticator to their ID.me account. Once linked, the push notification system provides a quick and secure way to approve sign-ins, adding an extra layer of convenience and security. Overall, the app offers flexible authentication options tailored to different user preferences and security requirements.
