iCloud is asking for my 4 digit iphone passcode but my passcode is 6 digits

Hey there 1984Robin,

Thanks for reaching out to Apple Support Communities. We're happy to provide some assistance.

Sounds like your device might be asking you for your verification code. Take a look here:

Two-factor authentication for Apple ID

Verification codes

A verification code is a temporary code sent to your trusted device or phone number when you sign in to a new device or browser with your Apple ID. You can also get a verification code from Settings on your trusted device.

A verification code is different from the device passcode you enter to unlock your iPhone, iPad, or iPod touch. 

We hope this helps.

Have a great day!

1984Robin,

We appreciate the clarification. Based on what's happening with the account recovery process, we recommend getting in contact with Apple directly: Get Support

Best wishes.
