After you set up authentication by SMS or voice, when you sign on to your account or app, you receive a passcode to use to authenticate.
- Voice call: you receive a phone call with an automated recording of your passcode
- SMS: you receive an SMS with details of your passcode.
Important:
If you are using voice authentication, consider protecting your secure voice codes. You can protect them in one of two ways:
- Change your voicemail password from the device default.
- Disable voicemail.
