How does Authenticate work?

The process involves using live mobile data to corroborate the integrity of the customer’s mobile device, allowing almost instantaneous access to a website or app without compromising security

Firstly, we check which operator owns the number, then, in conjunction with you and the operator, we definitively confirm that the device attempting log in is the one you expect it to be. This check requires no direct involvement from the user and eliminates a major risk factor in conducting your online business

Five benefits of using Authenticate

Reduces One Time Password friction

Passwordless authentication requires zero input from customers and keeps them engaged on your website or app without delay or distraction

Reduce log in abandonment

Frictionless customer login increases the chance of retaining new customers – because signing in doesn’t require them to remember a password, wait for an SMS or download anything

Increase the speed of login or sign up

Authenticate works significantly faster than any One Time Password system. So your customer can engage with you without delay

Reduced fraud and phishing attempts

Despite being widely used, SMS-based OTPs can be phished and used by fraudsters to take control of an account – if a phone number has been compromised. Authenticate uses the mobile operator’s own data to ensure that it hasn’t been compromised

Easily integrated into your current app or service

Authenticate provides a single interface to multiple network operators around the world, meaning you only need to integrate the service into your workflow once

Authenticate FAQ

Authenticate confirms the device connecting with your business has the same identity you expect (i.e.telephone number). It does this using data from the Mobile Network Operator that is encoded onto the SIM card contained within the phone. This cannot be copied or reproduced. Note that it is not authenticating the physical identity of the phone user, since it assumes that most modern smartphones will have other means (i.e. biometrics) to provide that function. Any fraudster attempting to copy attributes of the device to a new device that is under their control (i.e. cloning) will not be able to access the service.

On all Smartphones YES. Clearly the device needs to be internet enabled to make the authentication URL call.

No. There are multiple layers of protection built into the service and the data used by the operator to authenticate the device is not something that is publicly available or able to be cloned. Devices can still be potentially susceptible to SIM Swap fraud however because a SIM Swap is a social engineering type fraud and once executed the operator considers the new SIM to be correct. Therefore, where possible TMT still recommend performing regular SIM Swap checks.

The answer depends heavily on the operator and what country they are in, but typically a full authentication flow takes between 2 and 5 seconds. Don’t forget that silent authentications require no user input so the total time taken will normally be much lower than SMS OTP.
