When will Apple allow the use of third party 2FA? If a device happens to be stolen the user would then need to login to iCloud to disable the device thus pushing the built-in 2FA code from Apple to the stolen device allowing the thief to potentially attempt a login to the user's account.
Just seems like having an additional option would be an extra layer of security for your Apple Id.
"...pushing the built-in 2FA code from Apple to the stolen device allowing the thief to potentially attempt a login to the user's account."
Only if the thief has the passcode for the device.
Not sure how this would help if the thief has the passcode and the Apple ID password, but may be of interest:
