How to Add a Password to a RAR File

Author Info

Last Updated: December 10, 2024

A RAR file is a compressed archive that can contain hundreds of other files. RAR is popular because of how much the file size can be compressed, as well as the powerful encryption that is built-in. With just a few clicks, you can encrypt and password-protect any RAR archive. Without the correct password, unauthorized users won't even be able to see the names of the files it contains.
