Two-Factor Authentication (2FA)

Two-factor authentication (also known as 2FA) is an extra layer of verification offered to make sure the user accessing the information or service is actually authorized and the true requester.

2FA is used to make sure that people trying to gain access to an online service, account or data are who they say they are.

In its simple form, 2FA triggers a short-lived verification code when a user logs into the account or requests access to a service. The verification code is sent to the registered user’s mobile number when the access is initiated.

The registered user receives the code and can enter it into the form to complete the authentication process.

By implementing 2FA, a potential compromise of the account can be prevented if the user trying to access the account is not the owner of the register mobile number.

Using Reson8’s 2FA service, developers can easily add the 2FA service and get the site to send the user a unique one-time passcode (OTP) via a text message. The code is valid for a predetermined period of time and the recipient of the code must then enter the OTP back into the application form before getting access.

To learn more about Reson8 2FA, you can review the details of Reson8’s OTP and 2FA service and sign up for a trial account to test out the service.
