Hi everybody! , first  I would like to apologize if this has been asked before. I search in the forum (though it is different and new for me , coming from another distros  forums) and I didn't find the answers, mainly because I don't know which version my desktop is.
I don't remember having set "log in without password during installation", anyway , my "user and group" is set like this:
Password : "ask at startup"

but I don't know how to logg into my  LXLE with password
this is my system
