old ipad that has not used in years I FORGET MY PASSWORD

How old an iPad is this?

It may not be worth bothering with if it is an 9-10[-year old device.

What year and model iPad do you have/own?

The “A” model number can be found on aluminium back of your iPad in small print right under the larger bold print “iPad”.

huh?

I didn't solve anything for you, yet.

What “A” model number is your iPad.

Has an A followed by four numbers.

I won't be able to give you a definitive answer until I know the actual “A” model number of your “old” iPad.
