Why the password.trim()? Silently removing parts of the password can lead to dangerous bugs and tells me the developer didn’t peoperly consider how to sanitize input.
I remember once my password for a particular organization had a space at the end. I could log in to all LDAP-connected applications, except for one that would insist my password was wrong. A trim() or similar was likely the culprit.
Even if you computer is not exposed to the internet: are you certain that every other device on the network is safe (even on public wifi)? Would you immediately raise the alarm if you saw a second printer in the list with the same name, or something like “Print to file”? I think I personally could fall for that under the right circumstances.
