Yes, I'm using AT&T Active Armor.

Yep, the Recovery Key that it is requesting is not the one you use for your Apple Account. The instructions for Active Armor including when you forget the Master Password are available here:

So its asking for AT&T's Active Armor recovery key. You would need to figure out if what you set up in November was the security key fo the Active Armor or an actual Apple Recovery key for your Apple Account.

Those would be entirely different and unrelated. And if the key for the Active Armor is the one that has failed, you will need to contact AT&T for help with that.

I don't recall what security I was attempting to check, but to get into it I had to enter my master password. I couldn't find the Master PW, but to reset it I had to enter my Recovery Key. I knew I had just updated my Recovery Key in Nov. 2025, but when I entered it, it said it was incorrect!! Why and how??

Given the reference to a “master password”, that would all seem to be related to whichever third-party password manager you’re using. Are you using an add-on password manager?

I agree. Sounds like they are using a 3rd party password manager which requires a security key to unlock when the password is lost or unknown. This oif course would be different Apple's Security keys which are used to access an Apple account, when its password is forgotten and there is no access to a trusted device or phone number to recieve a Two-Factor Authentication code.

Recovery Keys are set for your Apple Account, not a specific device.

How are you trying to use the Recovery Key exactly?

Did you forget your password? Or don't have access to a trusted device to get a Two-Factor Authentication?
