Now, without further ado, here are two ways to password protect a PDF on your iPhone…
Way 1. Password Protect a PDF on iPhone via Adding Open Password

This will also help prevent anyone else from editing documents without your knowledge. Plus, being able to do all of this on your iPhone is a huge bonus because you can ensure file stay protected while on the go, and you can alter documents from anywhere.
