How the RCS OTP process works

Sending OTPs by RCS minimizes the chances of users being hacked since both their password and mobile device are required to access their accounts.

STEP 1

Customer logs into their account using their unique username and private password

STEP 2

This triggers an RCS message to their mobile device containing a unique one-time pin (OTP) to enable 2FA authentication

STEP 3

The customer enters the OTP into the authentication prompt on the login page

STEP 4

The identity verification process is completed successfully, and the customer can access their account securely
