If your iPad is disabled, or you have forgotten your iPad passcode, you’ll need to follow this process:

You’ll need access to either a PC (with iTunes installed) or a Mac (with iTunes or Finder - as appropriate for the installed version of MacOS). Use of either a PC or Mac computer is unavoidable, although the computer does not have to be yours - that of a willing friend or family member will suffice. Alternatively, you can visit the Genius Bar at an Apple Store in they have reopened in your region.

You’ll also need your AppleID and associated password. If these have also been forgotten, they can be recovered here:

To recover your credentials, you’ll need access to one of the following:

• Your primary email address mailbox that corresponds with your AppleID
• Any of the secondary/recovery email addresses that should be configured for your AppleID account
• Any of the trusted telephone numbers (fixed line or Cellular/Mobile) that are associated with your AppleID

Unless you AppleID account has not been fully/correctly configured, or has been seriously neglected, recovery of the AppleID and password should not be difficult.
