I forgot my iPad password, what I have to do?

Hi Toty2022, thank you for posting in Apple Support Communities.

I apologise if I have misread your post but do you mean iPad Passcode and if so the following link may help.

If the recovery mode steps did not resolve your iPad issue can you detail further what shows on your screen e.g. iPad is Disabled, Activation Lock and we can provide further support.

Having said that you may find it better to contact Apple Support.

You can do this as follows:

• Online:--> Genius Bar Reservation and Apple Support Options - Apple;
• Contacting a local Apple Store or AASP among the list provided above but also again as follows Apple – Location Selector; or
• Using the "Apple Support" app, available and downloadable from App Store.
