I am currently considering options for a web/intranet application login screen and this seems like a good place to share.
Not much work has gone into the current screen since creation and it exists as a dropdown list/box of usernames (fullname), password field and login button. The users seem comfortable with this (having existed this way for several years (they may be adverse to change)) but with the number of entries/users approaching 200 maybe it needs reconsideration.
I have observed some users "struggling" to find their username in amongst others, although some users are fairly comfortable with selecting the dropdown and typing. The system is often used in a manufacturing kiosk environment and so maybe typing should be minimal/minimised.
This screen can stay as is and I have plenty other things to develop (more features wanted at higher priority) but I am wondering if there are any good alternatives or suggestions. Autocomplete text box?
This situation leaves me with the following questions:
- Are there any "mental models" for login screens?
- Might there be any alternative options for username other than dropdown or text field?
- How do I deal with resistance to change of interface?
- Can anybody direct me to good literature on login screens/mental models?
