What is two-factor authentication?
Two-factor authentication (or 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.
We offer two-factor authentication on our website and the My BT app. It's optional.
How do I activate 2FA?
- Log in to My BT as normal using your ID and password, and follow the steps below. Please note that this cannot be done in the app.
- On your homepage, select 'Your details' at the top of the page.
- On your Profile page, select Set up two-step authentication.
- We’ll then ask whether you want your passcode sent to your email or mobile. You'll need to enter this passcode to confirm your identity and complete two-step authentication setup.
- You will then receive a text confirming that two-step authentication has been successfully set up.
We recommend keeping two-step authentication enabled to protect your BT Identities, but if you want to switch it off at any time, you can do so in your Profile.
Two-factor authentication troubleshooting
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 has been sent to your junk folder.
- Make sure the mobile number to which the passcode has been sent is correct.
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.
