How to generate Random password in Linux

I believe many inexperienced people don't know how to generate random passwords in Linux. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Use the mkpasswd utility to generate a password

Mkpasswd is installed with the expect package on RHEL-based systems. On Debian-based systems, mkpasswd is in the package whois. Installing the mkpasswd package directly will result in an error:

RHEL system: the package mkpasswd is not available.

Debian system: error: unable to locate package mkpasswd.

So install their parent package as described above, and there will be no problem.

Run mkpasswd to get the password

Now run the xkcdpass command and you will be randomly given several dictionary words like the following:

Root@kerneltalks # xkcdpassbroadside unpadded osmosis statistic cosmetics lugged

You can use these words as other commands, such as md5sum, to get random passwords (like the following), and you can even use the nth letter of each word to generate your password!
