Multiple user accounts, guest with no password

Postby MH » 2018-08-03 10:21

This should be a no brainer, but I'll be damned if I can find anyway to implement it. I have a system with multiple users. I want a guest account that does not require a password to login. I'm running KDE, so sddm is the login manager. I want the guest user to simply select the guest account and hit the "Return" key to login, no password required. Is this possible? If so, how?

I get "login failed" when attempting to login as a guest with an empty password. I'm running KDE, so maybe it has something to do with sddm?

I scanned your list of links, read two or three that seemed most relevant, just out of curiosity, because it seems you assumed I didn't try searching for an answer myself before posting. I saw nothing of any value there. The majority of them are gdm or lightdm related, not sddm, which it seems is the problem.

I previously came across numerous posts complaining about the lack of "guest login" (no password) with sddm, including some that were specifically a feature request. However, nothing within the past year and sddm has been updated since then. My assumption is the developers simply haven't implemented that capability.

So, have you checked that by trying light/gdm ?

Can the guest user log in at the console without a password?

I don't use a display manager but I did test my suggestion before posting :)

i have given up interpreting other people's posts, because it usually leads to confusion & discord.
no - i see what you write. if you don't share your (failed) attempts, i must assume there were none. simple.

also, your answer came only 20min after my answer. that's a little quick imo.

however, the search seems to suggest that kde's login manager does not have a guest account feature.

I tried using both lightdm and gdm sometime ago due to some other problems with sddm at the time. Neither was functional for me at that time, and the KDE folks insist sddm is what should be used. I haven't tried either since.

I did not check logging in from console. I assume that will work, since all evidence since my original post points to it being an sddm issue.

I shared my failed attempt, quite clearly I thought. The link you posted was the ONLY workaround I ever came across applicable to my situation. I did not try it, as I'd rather have to use a (shared) password than implement the suggested hack.

My approach would be to look for a way to notify the users, that the password for "guest" is "guest", for example :
