Thank computer programs for the combination of letters that is my member-name. "Keberoxu" in my case is a computer-program-generated password. All I did was click on a "generate password" square on the screen. If the word has a meaning, I am the last to know.

My "keberoxu" password will get you to my account with a library-oriented service which allows me to order, for a reasonable fee, a copy of something in a library collection, I'm not saying which service.
It's a very nerdy thing.
