Locked out of my older iPad

You need to know your Apple ID, Apple ID Password and Passcode. Do you know them? You say locked out. What is the message on your iPad screen?

Also a 10 year old iPad is virtually useless today. Those very old devices cannot fun the newer iPadOS versions and can't run most modern apps, which would mean no Netflix, Youtube, Facebook, etc.

It wasn't junk at one time. But time and technology have moved on significantly in more than a decade.
