I usually face low-level users (the kind of users who write their passwords on a post-it) who don’t use their computer in a daily basis, and sometimes they call me because they forgot their password. I can do nothing besides tell them to bring their computer and I will reset the password with the live CD method.
On Windows, they can use the 3 secret questions method for local accounts, and if you use an online account, you can reset your password though email validation or other methods, mac also offers some options to reset a forgotten password.
Obviously, those OSes are targeted to less tech-savy users, but I think it would be nice to offer a solution on Linux. The three secret questions seems to be the easiest one to develop, but sddm and the underlying desktop environment (or window manager) perhaps needs to be in “harmony”. At least, sddm should be able to change the user’s password if they answer the three questions, on the other hand, there should be a “wizard” asking for those questions inside the desktop (a secondary application).
I think devs from at least KDE and SDDM should agree to do their part of the job, KDE devs to do the wizard, and SDDM the logic to remember/reset the password using the secret questions entered by the user.
What do you think? It’s this even doable? I’m going to open this discussion as well on SDDM’s github https://github.com/sddm/sddm/issues/1913
because I think this cannot be implemented lonely by Plasma devs.
EDITED: I’m not talking about giving support to my corporate users or my friends or something like this. I think it’s a missing feature other OSes has and Linux don’t: give the ability to home users to reset their password by answering some secret questions at the login screen itself.
