Tips and common mistakes

Choose a password you can remember and others cannot guess

Use a long phrase or a mix of words, numbers and symbols rather than a birth date. Write it down somewhere safe, because a lost password usually cannot be recovered.

Share the password separately

Send the PDF in one message and the password in another, ideally through a different app. That way a single lost message does not give access to the file.
