SMS Two Factor Authentication (Dual Factor Authentication) is a security verification procedure, which is triggered through a user logging into the TextP2P application. In the log-in process, the user is automatically sent an SMS to their mobile number containing a unique numeric code. This 'token-code' is then inputted by the individual, verifying themselves as the user logging into the online account.
This process significantly reduces the ability for online data to be compromised as only the user with the linked phone number will be able to access the account at the time.
You can enable two factor authentication by going to your account profile screen.
Then when you go to log into TextP2P, after you have entered your username and password you will be sent a text message and will be asked to verify the code.
If the code is successfully verified, the user will be allowed into the application.
