Establish a Global Trust Anchor

Ensuring the validity of your users is extremely important in preventing fraud and securing accounts from compromise. A great way to do that is to attach a verified phone number to end-user accounts, ideally when they first register. From there, that user’s identity can easily be confirmed when they access their account from a new browser or device or attempt a high-value transaction.

Phone verification using SMSGATEWAYHUB SMS Verify is easily integrated into any existing application, user experience or workflow using a REST API. The following is one example of how to use the product to verify the identity of a user attempting to access their Web account from a new device.

  • 1) The user visits your website and enters their existing credentials (username and password) to access their account.
  • 2) The user already provided a verified mobile phone number when they first registered for an account.
  • 3) Because this is the first time the user is accessing their accountfrom a new device, a challenge is needed to further verify the user and permit them to complete the login attempt.
  • 4) SMS Verify sends a time-based one-time passcode to the user’s mobile number and at the same time, the user is shown a secondary login screen in their Web browser with a prompt to enter the passcode once it is received.
  • 5) Once the user receives the passcode to their mobile device, they simply enter it in on the webpage as prompted.
  • 6) You confirm with SMSGATEWAYHUB that the passcode entered is the same code that was sent to the user and, if matched, the user is verified.
  • 7) The user is then able to access their account.
