Hello I forgot my password to a very important document on pages is anything you can do? Please help!

There is no means to crack that Pages document password, unless you remember it.

However, if it was on your Mac before the password was set, and you have a Time Machine backup, you might be able to find an older version of the document before the password was set, and restore that.

If you shared the document with anyone else before setting the password, you might be able to retrieve the document from them.
