IPad Code what is it for?

Enter the passcode used to set up the iPad. If you do not know it and you see a waiting period you can wait and try again. If the iPad is actually disabled, or one for which you have forgotten the passcode, Apple provides different solutions depending upon the system version you are using and other criteria.

For devices with iPadOS 15.2 or later* you may be able to use the method in this support article: If you see an iPhone or iPad unavailable message or Security Lockout screen - Apple Support This does not require a computer.

If your device is still running iPadOS 15.1 or earlier, you will need to use the method in this support article: If you forgot your iPad passcode - Apple Support

You may also need to use this method if:

• your device is not connected to a cellular or Wi-Fi network (if you restart your device when you see "Security Lockout" on the Lock Screen, you won't be able to reconnect to a Wi-Fi network until your device is unlocked. Cellular devices will reconnect to a cellular network if you have active service).

• you do not have your Apple ID and password that you used to set up your device.

*These models, when running iPadOS 15.2 or later, do not require a computer:

iPad Air2, iPad mini4 (if updated)

iPad Pro

iPad Air 3rd generation and later

iPad (5th generation and later)

iPad mini (5th generation and later)

Here are resources if you are prompted for your username and password and have forgotten them:

If you forgot your Apple ID email address or phone number - Apple Support Note that typically this is an email address you use.

If you forgot your Apple ID password - Apple Support

If you do not have a computer, use this link Find Locations to find an Apple service location, or ask a friend if you can use theirs. This can be a Mac, or a PC with iTunes.

Whichever method you use will result in erasing the iPad. You can, however, restore it from a backup as described in this support article --> Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

The 4 Digit code would normally be the screen unlock code, it does not come from Apple at all, it would have been set by your sister. Who ever has the code can enter it at the lock screen and access the iPad.

From there, you would still need to know your sister's Apple ID and password, so that they can log off and turn off Find My, and can restore the iPad to factory settings to remove all of your sister's data.

If you don't know your sister's Apple ID or password, you will have to request access to her account.

The new user, must log out of your sisters ID form the iPad before its deleted. If you wait until its deleted it won't be possible to log off and the iPad will become unusable.

Get Access to her account, have the new owner log out, and then request the deletion of the Apple ID.

Once you have access, they can log off.

You can't have the Apple ID deleted if you don't have access to it.

one of the Apple Techs said to make sure the notepad is turned off and disconnected from wifi bafore any deletion etc is done.

That is not really useful in any way. Having it disconnected will not change anything regarding the logged in Apple ID.

thanks for reminding us of that, Phil.

one person at Apple suggested that because there is NO activation lock on the iPad ( she can see that apparently) that the easiest way to get access to the IPad is to reset it to Factory Defaults

do you see any problems with doing that?

Activation Lock will kick in when its restored to Factory Defaults if the Apple ID is still logged in and Find My is turned on.

If Find My is not turned on, then yes, restoring it will work.

But since they cannot access the iPad or the Apple ID, there is no way to know if Find My is turned on.

If your intention is merely to fully erase the iPad, repeated input of an incorrect Passcode will very likely cause the iPad to automatically erase after ten incorrect Passcodes have been entered.

All locally stored data is encrypted; by design, without the Passcode, data cannot be retrieved from the device. The iPad Passcode unlocks the encryption keys necessary to access local stored data.

What code?

The screen unlock passcode?

A one time code sent by Apple?

You'll need to explain exaclty what you are trying to do, and where this "code" came from.

Yes. In Settings ➜ Apple ID ➜ Find My.

If Find My is turned on there, the password for the Apple ID will be required to turn it off.
