Authenticator App for British Airways: How to Use MFA

British Airways supports multi-factor authentication (MFA) with an authenticator app.

If you chose an authenticator when setting up MFA, your British Airways verification code appears inside that app rather than arriving by SMS.

British Airways currently gives Microsoft Authenticator and Google Authenticator as examples of supported authenticator apps.

Does British Airways Support Authenticator Apps?

Yes.

British Airways supports authenticator-based MFA for British Airways account login.

When MFA is enabled, your six-digit verification code can come from either:

• A registered mobile number by SMS
• An authenticator app

British Airways specifically states that authenticator users can retrieve their current six-digit code from apps such as Microsoft Authenticator or Google Authenticator.

You do not need a special application called “British Airways Authenticator.”

Instead, you use a compatible authenticator connected during MFA setup.

How British Airways MFA Works

Your normal British Airways login can use:

• Membership number and password
• Username and password
• Registered email address and password

After the first login step, British Airways may ask for an additional MFA code.

If you previously selected an authenticator app, the process is:

British Airways login → MFA prompt → Open authenticator → Enter six-digit code → Account access

The authenticator generates a new temporary code for the British Airways account.

Unlike SMS-based verification, you should not expect a text message when authenticator-based MFA is active.

How to Set Up an Authenticator App for British Airways

During British Airways MFA enrollment, choose the authenticator-app method when it is offered.

The setup flow will provide the information needed to connect your authenticator.

The general process is:

1. Sign in to your British Airways account.
2. Open the MFA setup or security flow.
3. Choose Authenticator App.
4. Open your authenticator.
5. Add the British Airways account using the setup information shown.
6. Enter the generated six-digit code back into British Airways.
7. Complete MFA setup.

Depending on the setup screen, your authenticator may ask you to scan a QR code or enter a setup key manually.

Only use setup information displayed inside the official British Airways account flow.

How to Find Your British Airways Authenticator Code

If British Airways asks for a six-digit verification code and you use an authenticator:

1. Open your authenticator app.
2. Find the British Airways entry.
3. Read the current six-digit code.
4. Return to British Airways.
5. Enter the code before it changes.

British Airways notes that you will not necessarily receive a notification when a new authenticator code is available.

You need to open the authenticator and view the current code directly.

If you have several accounts in the same authenticator, make sure you are using the British Airways entry.

Google Authenticator for British Airways

Google Authenticator can be used when British Airways MFA is configured with an authenticator app.

British Airways explicitly lists Google Authenticator as an example in its login-help documentation.

After setup, open Google Authenticator whenever British Airways asks for MFA verification and enter the current six-digit code associated with the account.

Do not try to create a British Airways entry manually unless British Airways provides the setup information during MFA enrollment.

Microsoft Authenticator for British Airways

Microsoft Authenticator is also explicitly supported as an example by British Airways.

The usage flow is the same:

1. Sign in to British Airways.
2. Wait for the MFA prompt.
3. Open Microsoft Authenticator.
4. Find the British Airways entry.
5. Enter the current six-digit code.

The code is generated inside the authenticator, so no SMS is required when this MFA method is being used.
