Things to know
- It is best practice to not share numbers or use another person’s phone number for MFA
- Enter your phone number with no spaces.
- Submitting the phone number multiple times will inactivate previous codes. If you keep receiving 'expired' messages, then the latest code has not been sent to your phone.
- There are some limitations to sending SMS messages to mobile devices in India. For more information: Limitations sending SMS messages to Indian mobile devices
