Keyfile

A keyfile is like a secret code that helps keep something safe. It's like a special password that lets only certain people open a special door or box. Think of it like when you have a secret diary with a lock, the key to the lock is the keyfile. Just like how you need the key to unlock your diary and read your secrets, you need the keyfile to unlock or access something important.

With computer programs, keyfiles work in a similar way. They're used to keep things secure, like computers, files or even bank accounts. Just like a diary, you need to have the key, or the keyfile, to get access to these important things.

Keyfiles are often used as an extra layer of security, alongside a regular password. It's like having two passwords instead of one, which makes it much harder for bad people to get in and see your stuff. For example, some computer programs use a special keyfile instead of a password, to make it even harder for hackers to get in.

Overall, keyfiles help to keep things safe and secure by adding an extra layer of protection to important files, documents or even your computer.
