How To Bypass Apple ID Activation Code

You can't bypass it, you need to type in the id and password to activate and access the device, that is the point of activation lock.

If you can't remember your id then do you have any of it's downloads on your computer's iTunes : Recovering a forgotten iTunes Store account name ?

Or see if you can get your id via http://iforgot.apple.com or http://appleid.apple.com : Apple ID: How to find your Apple ID

There is no method to bypass it, contact apple and have them assist you in retrieving or resetting your password for that ID.

That is your only option.

That cannot be bypassed, it is an anti-theft protection system. If you set Find My in Settings > iCloud your only hope is to remember the Apple ID and password to turn that off, or remember how to login in to your iCloud account, go to Find My Phone and remove the iPad from the devices list. That will release it.
