Must I enter Apple ID during reset

If a person is going to pass on an iPad to a new owner, can the Apple ID wait to be set up or must it be entered during the reset after erasing process?

 

It can wait, but then you won't be enjoying most features of the amazing iPad.

 

You must enter your Apple ID during the erase/restore process. The new owner may wait as long as they like before signing up and/or entering their own Apple ID; though as abababababab said they will be missing some features until they do.

 

If you skip the screen where it asks to chose your apple user name and password, i understand it says you will lose some abilities.
How would you do it at a later date?
My daughter has not properly set up an e mail address ( She is in the process of changing providers) and will want to do it later.
Also can you change your user ID ?

 

You can Log-in to your Apple ID by entering your Apple ID and password from Settings > iTunes and App Store.

To change your Apple ID, tap on your account from Settings > iTunes and App Store and select Log out. Perform the above steps to log in into a new ID again.

Note that you cannot be logged in to 2 Apple IDs in the same device simultaneously.

 

Thank you so much. Great information
I was wondering if its possible to change a user name though having set it up

 

Username can be changed, but if you want to keep the email notifications about Apple going to the same e-mail address, its not possible. You can only change your Apple ID username, while also changing the e-mail address linked to your Apple Account.

Here is the website from where you can change your Apple ID : https://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/wa/directToSignIn?localang=en_US

Here are the steps. Please note that I have already selected 'manage my account', you need to login on that page with your existing Apple ID : Apple ID: Changing your Apple ID
