Sending a PDF e-mail attachment is quite common, but do you generally find a PDF file is truly secure?

If not, here's how to password-protect your PDF:

It's critical to use a strong password to secure your PDF file. Someone might be able to guess your password and open your document if you create a weak password.

Create a passcode that no one else can guess; make it as long as possible by using a mix of lowercase and capital letters and numbers. Don't include your details or words if you don't want people to guess your details or the words you use in your password.

If you're dealing with sensitive data saved in PDF format, you'd want to ensure that you’re using a reputable online service.
