💖 KPASSWD(1) 💖

okay bestie, so you wanna know about kpasswd? it's a MIT Kerberos girlie, manual page 1, and she's here to help you change a user's Kerberos password. let's get into it 🫶

✨ NAME ✨

kpasswd — change a user's Kerberos password 🔑

🌸 SYNOPSIS 🌸

kpasswd [principal]

💅 DESCRIPTION 💅

okay so the kpasswd command is literally the way to change a Kerberos principal's password. here's the whole vibe: first it prompts you for your current Kerberos password, then it prompts you twice for the new password, and then boom — the password is changed. periodt ✨

now, if the principal is governed by a policy that specifies the length and/or number of character classes required in the new password, then your new password has to conform to that policy. no exceptions, bestie, the policy said what it said 💀

the five character classes are: lower case, upper case, numbers, punctuation, and all other characters. (yes, "all other characters" is a whole class, iconic honestly 👑)

🎀 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, the principal is derived from the identity of the user invoking the kpasswd command. so like, it figures it out for you 🧚

🌈 ENVIRONMENT 🌈
