You can share your notes using other apps or services such as Mail, Facebook, and more.
Click the Share button 
, then choose an app or service.
Note: If you share a locked note while viewing it, the shared version can be viewed without entering a password.
When you share a note this way, you just send a static copy of the note—recipients can’t make changes to the note or see an updated version of the note unless you share it with them again. To allow others to edit a note and see the latest version at any time, add people to the note.
