Phone Verification

Confirm the identity of your end-users by attaching a verified phone number at registration and authenticate them throughout the account lifecycle.

Global Account Trust Anchor

  • Collect a valid phone number when a new user attempts to open an account.
  • A time-sensitive one-time passcode is then sent to the number provided using SMS or a voice call.
  • The user inputs the correct code into the login screen, then the phone number is verified, and a secure account lifecycle begins.

Full Spectrum End-User Account Security

  • Establish a Mobile Identity
    Verify a unique identity for each legitimate user through their valid phone number. Quickly and easily attach a verified number to an account during registration for added assurance that the account owner is who they say they are.
  • Prevent Fraudulent Account Registrations
    Confirm the account registrant is not from a bot or spammer registering thousands of fake, bulk accounts and glean valuable data attributes based on the phone number provided.
  • Protect Account Access and Usage
    Secure logins from unknown devices and transactions by using SMS and voice messages sent to a verified number or through built-in two-factor authentication (2FA) to existing mobile applications that include  “one-click” push notifications, code challenges and soft tokens.
  • Streamline Secure Account Recovery
    Automatically reset a user’s lost password, or when there is risk of an account breach, securely and easily send an SMS message or voice call to the verified number.
