how to unlock ipad passcode without computer

To unlock an iPad passcode without using a computer, your main options rely on Apple's iCloud service and the Find My iPad feature, provided certain conditions are met:

• Use iCloud's Find My iPad to erase the device remotely :
  If your iPad has "Find My iPad" enabled and is connected to the internet, you can go to iCloud.com from any other device, sign in with your Apple ID, select your iPad under "Find My iPhone," and choose "Erase This Device." This will erase all data including the passcode, allowing you to set it up again. Note that this method requires your Apple ID credentials and internet connection on the iPad, and it will wipe all data on the device. After erasing, the device will still require your Apple ID password to reactivate due to Activation Lock

• Use the "Forgot Passcode" option on iOS 15.2 or later :
  If your iPad runs iOS 15.2 or later, is connected to a network, and you have signed in with your Apple ID and enabled Find My, you may see a "Forgot Passcode" option after entering the wrong passcode multiple times. This allows you to reset the passcode directly from the lock screen without a computer, using your Apple ID credentials

• Siri workaround (limited and outdated) :
  There was a Siri exploit that worked on iPads running iOS 8 to iOS 10.1, allowing limited access without a passcode, but this is outdated and not reliable on modern devices

• Without a computer or Apple ID access, unlocking is generally not possible :
  If you do not have access to a computer or Apple ID credentials, or if Find My iPad is not enabled, unlocking the iPad without the passcode is effectively impossible, and Apple recommends contacting Apple Support or visiting an Apple Store for assistance

In summary, the most practical way to unlock an iPad without a computer is to use iCloud's Find My feature to erase the device remotely, provided you have your Apple ID and the iPad is online and linked to your account. Otherwise, unlocking without a computer is not feasible. Steps for iCloud erase method:

1. On another device, open a browser and go to iCloud.com.
2. Sign in with your Apple ID used on the locked iPad.
3. Select "Find iPhone" (which also covers iPads).
4. Click "All Devices" and choose your locked iPad.
5. Click "Erase iPad" and confirm.
6. Wait for the device to erase and restart.
7. Set up your iPad again and enter your Apple ID password to bypass Activation Lock

This is the officially supported method to regain access without a computer.
