Two-factor authentication (2FA)

We offer a suite of two-factor authentication (2FA) products so you can implement
more secure identity verification for all users on any channel or device.

Mobile Push

The simplest way to do 2FA.

After logging into an application with your password, you receive a push notification on the mobile app, prompting you to authenticate. With a simple tap on the screen, or a biometric scan, your identity is quickly verified.

SMS Authentication

A smart way to reach users without smartphones.

After logging into an application with your password, you receive a text on your mobile phone with a passcode. Enter the passcode into the application to complete the authentication. Works with all phones with an active cellular service. Does not require a smartphone or a data connection.

Voice Callback Authentication

Believe it or not, not everyone texts. Cellphone or landline, we’ve got it covered.

After logging into an application with your password, you receive a passcode via an automated phone call on your previously registered phone. You are prompted to enter the passcode into the application to complete the authentication. Works with mobile phones and landlines and does not require a touch-tone phone.

Time-based One-time Passcodes (TOTP)

Smartphone but no signal – login nightmare?! Cover your bases with locally generated passcodes on the ThumbSignIn app.

After logging into an application with your password, a one-time, 30-second passcode will be generated by the ThumbSignIn app on your phone. You are prompted to enter the passcode into the application to complete the authentication. No Internet connection or phone connection needed. Requires installation of the ThumbSignIn app on the user’s smartphone.
