SMS in Two-Factor Authentication
SMS can be used to as an authentication (2FA) method in two-factor authentication. You can use a built-in 2FA account to handle SMS authentication, but if you have an SMS account configured for messaging, you can also use that account to handle authentication.
- To enable an SMS account for 2FA, when configuring your SMS service, select Two factor authentication under Usage.
- Go to Setup > Access > Two Factor Authentication.
- In the Two Factor Authentication screen, select Text message (SMS) under Authentication Method and confirm the message content.
- In the SMS Account drop-down, select the SMS account you configured above.
- Click Finish.
Now, when someone logs in, they receive an SMS message with a security code.
