I forgot my iPad password

Would this be your iPad Passcode, or your AppleID Password?

An iPad passcode cannot be recovered, reset or modified from another device. If your iPad is disabled, or you have forgotten your iPad passcode, you have no alternative other than to follow this process:

If you’ve forgotten the passcode on your iPad, or your iPad is disabled – Apple Support

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).

Download and use iTunes for Windows – Apple Support

Update to the latest version of iTunes – Apple Support

Use of a PC or Mac is unavoidable. If you don’t have access to a suitable computer of your own, that of a helpful friend or family member will suffice. Alternatively, the technicians at the Genius Bar of your local Apple Store will be delighted to assist.

You may 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.

More information about recovery of your AppleID:

When you recover access to your credentials, you would be well advised to log-in to your AppleID account from a web browser - and verify/update any email addresses and trusted telephone numbers:

If you have iPadOS 15.2 there will be an option that says Erase iPad if you have a WiFi connection.

Otherwise,

Put your iPad in recovery mode.

1. Make sure that your Mac is up to date. If you're using iTunes, make sure you have the latest version of iTunes. 
2. On a Mac with macOS Catalina, open Finder. On a Mac with macOS Mojave or earlier, or on a PC, open iTunes. If iTunes is already open, close it, then open it again. Find out which macOS your Mac is using.
3. Keep your device connected and wait until the recovery mode screen appears:

• • iPad models that don't have a Home button: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Top button until your device begins to restart. Continue holding the Top button until your device goes into recovery mode.
  • iPhone 8 or later: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then, press and hold the Side button until you see the recovery mode screen.
  • iPhone 7, iPhone 7 Plus, and iPod touch (7th generation): Press and hold the Top (or Side) and Volume Down buttons at the same time. Keep holding them until you see the recovery mode screen.
• iPad with Home button, iPhone 6s or earlier, and iPod touch (6th generation) or earlier: Press and hold both the Home and the Top (or Side) buttons at the same time. Keep holding them until you see the recovery mode screen.
  • 

Then follow the recovery mode process-

Get your device ready

1. Make sure that your Mac or PC is updated. If you're using iTunes, make sure that you have the latest version.
2. If you want to save the information on your iPhone, iPad, or iPod, make a backup.
3. Go to Settings > [your name] > Find My, tap Find My iPhone, then turn it off. Learn what to do for an unresponsive device or one that won't turn on. Get help if you forgot your passcode.

Restore your device to factory settings

1. On a Mac with macOS Catalina or later, open Finder. On a Mac with macOS Mojave or earlier, or on a PC, open iTunes. Find out which macOS your Mac is using.
2. Connect your device to your computer.
3. If a message asks for your device passcode or to Trust This Computer, follow the onscreen steps. Get help if you forgot your passcode. 
4. Select your device when it appears on your computer. Learn what to do if your iPhone, iPad, or iPod touch is unresponsive or won't turn on. Or get help if your device doesn't appear on your computer.
5. Click Restore [device]. If you're signed into Find My, you need to sign out before you can click Restore.
6. 
7. 
   
8. Click Restore again to confirm. Your computer erases your device and installs the latest iOS, iPadOS, or iPod software.
9. 
10. 
    
11. After your device restores to factory settings, it restarts. Now you can set it up as new.

I hope this helps. Have a great day.
