I lost the passphrase for my account on a server. I have spent more time configuring the settings of the server than I have putting files in my home directory so I want to know if I can just delete the encrypted one and make a new home directory.
Easiest would be to delete the user including it's home folder and make a new one.
As guntbert pointed out you need to pay attention that there is always at least one account which can use
To get rid of the encryption only I would try looking at
But that won't change the passphrase of your user, you would still need to do that.
