I forgot my password

Hey latifmohammadyar,

Thanks for the question. I understand that your iPad is disabled with an unknown passcode. The following article may help to resolve your issue:

The article includes steps for iTunes, however if you have never synced with iTunes (or do not have access to the computer) follow these steps:

If you don't have access to a computer

If you are using Find My iPhone, you can use Remote Wipe to restore your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode.

Thanks,

Matt M.

If you forgot (or don't know) your passcode, restore the device from backup on the last computer it was synced with when the passcode was turned on... this will remove the passcode. If you do not have access to the last computer it was synced with, you will have to force it into recovery mode & restore as a new device.
