I change my passwords on a regular basis, and this is my routine for changing passwords everywhere.
Generate new password
Change Ubuntu keyring password
Select ‘Passwords’-tab, right click on ‘Passwords’-folder and select ‘Change password’ .
Change ssh passphrase
henning@localhost:~$ ssh-keygen -p
Here you will find some of my thoughts and experiments from my daily life of programming and general geeking ;)
