Unable to Access Microsoft Authenticator 2FA codes After Changing my phone

Hi,

I recently changed my phone and thought I had successfully transferred all my data from the old iPhone to the new one.

I wanted to log into my WordPress site, which I had set up with 2FA on the login screen, and when I opened the Authenticator app for the first time on my new phone, I could not see any codes. I had to login into my account again, but still nothing shows.

Now, I don't know how to login into different sites which require a code. It appears I also cannot access any iCloud backup from the previous phone.

What should I do now?

I have two Microsoft accounts and have also logged into the second one in the Authenticator app because I could not remember which account I had used for the 2FA codes.

The sites I usually log into aren't showing the option to scan a QR code again because I had previously logged in successfully.

Please help. Thank you.

    It seems that you need to configure your accounts in the Authenticator app on your new iPhone. If you're signed in on your computer, follow these steps:

    Access Your Security Info: Go to https://mysignins.microsoft.com/security-info and sign in with your account.

    Remove and Re-add the MFA Method: Under your security info, you’ll see your registered MFA methods (such as the mobile app for notifications). Remove the existing MFA method, then click Add method to set up your new device or update your settings.

    OR

    If you have access to Entra ID in the Azure portal, navigate to Azure Active Directory > Users. Select the user who needs to reset their MFA settings, and then look for options like Authentication methods or Multi-Factor Authentication settings in the user's profile.
