How do I unlock my ipad if I have forgotten the passcode/

If your iPad has iOS 15.2 or later installed, see: How to reset your iPhone, iPad, or iPod touch when you forgot your passcode - Apple Support

If that option is not available, you will need to use a computer. See: If you forgot your iPad passcode - Apple Support

There is no way to unlock your iPad if you forgot the passcode unless using some third-party unlockers. But these tools are not as safe as you imagine. Some of them may damage the Apple ecosystem and make your device a brick. If you have to unlock your device anyhow, just take the receipt of your device to the nearby Apple Store to ask for the help of the Apple technician.

The following is the same procedure that an Apple Store will do. It can be done by anyone without taking it to an Apple Store. If you forgot your iPad passcode - Apple Support
