Hi.
Example scenario. At my login screen it does not show the possible username(s) to pick from. If someone tried to login as Zac with the password Tulip -- could I find that out? Or at least the failed login usernames anyway?

I don't know if it shows passwords of failed logins (haven't tried it), but /var/log/lightdm/lightdm.log logs everything related to logins. You need to be root to view it though.

Are you using LightDM?

How about /var/log/auth.log ?

You could try the command 'lastb'. You probably must be root on ubuntu, because of the access-rights of the /var/log/btmp. (However I see my system is not logging to this as it should.)
Another file you can look at is /var/log/auth.log . Agian you must be root, and you may have to activate it by uncommenting the lines in /etc/rsyslog or /etc/rsyslog.d/50-default.conf, and touching /var/log/auth.log . Just look at the auth-log file with less or use grep.
Both will show you which users have tried to log-in with invalid passwords and if unknown users have tried to log-in. You should also see when and from where. Neither let you see the actual password used though.
