Protect from fraud

How it works

Verify verifies the idenity of your user. When a user logs into his account on your app, Verify sends a one-time verification code to the phone number associated with the username and password, via an SMS, voice message or push notification. The user enters the verification code into the input box presented by your app. This confirms that the person attempting to access the account has the phone linked to that account. Your app then gives full access to the user.

You only pay for successful verifications.


Intelligent fail-over

Adaptive routing

Pay per verification
