I have a iPad from my Aunt that has passed away. I do not know her Apple ID or password although I do know her unlock code. Is there anyway to reset or have apple reset this iPad ?

What you are finding is Activation Lock or related to it. This is a security feature, in part to deter re-selling of stolen devices. Click on the link to read more about 'Activation Lock for iPhone, iPad, and iPod touch' --> http://support.apple.com/HT201365

An activation lock can only be removed using information for the account that applied the lock. If you know this information follow the onscreen steps to enter the Apple ID and password used to set up the device, or enter the device passcode.

If the required information is not known, the official owner of the deceased person's things as can be proven by documentation needs to try one of these things:

Read this link to discover "How to request access to a deceased family member's Apple accounts" [and devices] - https://support.apple.com/HT208510

OR

- Apple can remove a lock if a person can provide sufficient evidence of valid ownership. Do this online here --> https://al-support.apple.com/#/additional-support Apple says, "Proof of ownership documentation is required," but does not state what constitutes proof. This might be similar to what is required in the previous section.

Alternatively you may be able to do this at an Apple Store.

If you are able to unlock the device then you can take a backup of any important data to your Mac or PC (https://support.apple.com/en-gb/guide/iphone/iph3ecf67d29/ios)

You can reset the apple id password if you have acces to the email it is associated to (https://support.apple.com/en-gb/HT201487)

(You can find this in the iCloud section of settings)

To reset the device you need either the apple id username and password or last passcode used on the device to reset it because of activation lock (https://support.apple.com/en-gb/HT201365)

If you have either of these (verify the passcode unlocks the iPad if you plan to use that) then you can reset your iPad from settings or with a computer (https://support.apple.com/en-gb/HT201252)
