A handset is the easiest way to establish the identity of a user and you can use either SMS or Voice.
SMS Text-Message and Voice-based 2FA
With two-factor authentication gaining ever increasing recognition as a security staple both for individuals and companies, it's worth looking at the most common types of 2FA:
With SMS text-message and voice-based two-factor authentication, users provide phone numbers at the point of registration and whenever they need to log in to their account, a single-use code is generated and sent to the phone number they specified. This can be sent as an SMS or a phone call.
If you are familiar with either Apple or Google ecosystems you will be familiar with login notifications. They simply warn you when a login is taking place on one of your other devices. This might be a browser on a desktop or a tablet.
The prompt includes the estimated location of the login based on the IP address. With systems like this Trusted Devices method, the user then gets to decide whether to approve or deny the login attempt.
Voice calls are inherently more secure than SMS. The messages are not saved on the customer’s device and a voice call cannot be intercepted.
2FA is no use if your customer has to wait around to receive the security codes. With the Kawler API our partners are connected directly to all UK and US carriers and 600 networks worldwide.
