How to choose a good password
A password should be
- kept secret
- changed on a regular basis
- not be easy to guess by others (like your Matrikelnummer or 'klausi1' for instance)
To choose a password which is not easy to guess, use a non predictable combination of upper/lower case letters along with numbers and special characters. To help you create a safe password log in via ssh to login.coli.uni-saarland.de (using your old password) and start 'apg'
ssh login.coli.uni-saarland.de apg -a0 -MNLC -t -m10 -x10
You may choose any of the suggestions, if you like you can modify them a little.
