About two-factor authentication
Two-factor authentication (2FA) is a way to log in that requires you to confirm your identity in two ways. It will help keep your account and identity more secure, as it is safer than relying on a password alone.
2FA is set up when you create your BT ID and cannot be removed to ensure your My BT account remains secure.
I received my passcode?
If you have two-step authentication set up but haven't received the passcode, there are a few things you can check:
- Check whether the passcode is in your email junk folder.
- Make sure the mobile number to which the passcode has been sent is correct.
How do I change where a passcode is sent?
If you change your email address and/or mobile number, it is important that you update your two-step authentication information so that you can access the passcode.
You can change where your passcode is sent by following the steps below:
- Log in to My BT online.
- Select Your Details.
- Select Edit two-factor authentication.
- Follow the steps to change your passcode destination.
