temporary support pin

Hi o25nu,

welcome to the Apple (user-to-user) Community!

Re: temporary support pin

Wondering if this is the one-time code that you need to use when logging in to your Apple ID with 2 factor identification:

If so:

Whenever you sign in with your Apple ID on a new device or browser, you'll confirm your identity with your

password plus a six-digit verification code.

There are a few ways you can get a verification code.

You can use the code displayed on your trusted device,

get a text or phone call,

or

generate a code from your trusted device.

See Apple Support's online article for all the details:

How to: Get a verification code and sign in with two-factor authentication - Apple Support

Eg: If you can’t receive a verification code on your trusted devices automatically,

you can get one from Settings, even if your device is offline.

From your iPhone:

If your device is online:

1. Go to Settings > [your name].
2. Tap Sign-In & Security > Two Factor Authentication.
3. Tap Get Verification Code.

If your iPhone is offline:

1. Go to Settings > [your name].
2. Tap Sign-In & Security. 
3. A message says "Account Details Unavailable." Tap Get Verification Code.

All the best :-)
