How it works
A user, logging into an account, first confirms their username and password, but to be certain that the user is who they say they are, Nexmo Verify gets involved. Nexmo sends a one-time code — via SMS, voice, or push notification — to the phone associated with that username and password. When the code arrives on the phone belonging to the user associated with the account, the owner keys in the short verification code into the input box presented by the app. Your app verifies that the entered code matches the code that was sent, confirming that the person attempting to access the account has the phone linked to that account. Your app can then give full access to the user.
