✨ KPASSWD(1) — the MIT Kerberos era ✨

okay bestie, gather round, because we're talking about kpasswd, aka the glow-up button for your Kerberos password 💅 this one lives in the MIT Kerberos fam and honestly? she's iconic.

🌸 NAME 🌸

kpasswd — change a user's Kerberos password 🔑

🎀 SYNOPSIS 🎀

kpasswd [principal]

🦋 DESCRIPTION 🦋

So like, the kpasswd command is literally the way you change a Kerberos principal's password. no cap. 💖

Here's the whole vibe check of how it goes down:

  1. kpasswd first prompts you for your current Kerberos password.
  2. then it prompts you twice for the new password.
  3. and then, boom, the password is changed. slay. ✨

Now listen, if your principal is governed by a policy that specifies the length and/or the number of character classes required in the new password, then your new password has to conform to that policy. periodt. no sneaking around it. 🙈

and in case you were wondering what counts as a character class, the five character classes are:

  • lower case
  • upper case
  • numbers
  • punctuation
  • and all other characters

that's the whole list, bestie. five of them. memorize it, it's giving quiz energy. 👑

💜 OPTIONS 💜

  • principal — Change the password for the Kerberos principal principal. Otherwise, kpasswd uses the principal name from an existing ccache if there is one; and if there isn't one, then the principal is derived from the identity of the user invoking the kpasswd command. so basically it'll figure out who you are, but you can also just tell it. main character energy either way. 💅
