A few days ago, Jakob Nielsen posted an article in which he recommended displaying passwords in plain text instead of masking them. You should read the article
if you haven't already. I've read some of the reactions on the Internet
and I think people are so passionate about this topic. Here are a few
of my thoughts on this problem.
People often mistype passwords
If you ever performed usability testing you will know this true.
Sometimes it can take users 30 or more seconds for a simple login
activity! And that can be frustrating. However I think this goes far
beyond simple mistyping.
Password managers
I believe we all agree that password masking is necessary for
public/shared computers. But there is really simple solution for
non-shared computers: password managers that are integral part of
browsers. Just think this way: how many times you actually type your password on a home
computer?
People are paranoid
Is plain text passwords what users would expect? How would avarage user behave in case
of typing plaintext password? People feel uncomfortable, even paranoid,
when leaving sensitive data and that includes passwords. Offices are often shared with one or
more employees so looking over a shoulder is very common practice. No matter how reasonable it actually is, masking passwords at least gives the feel of privacy.
Optional masking
As one of the solutions, Jakob suggested adding a checkbox that can
turn masking on/off. Making too many options could make authentication
process painful for users.
Imagine that some websites mask password, other don't. Some even have
optional masking. Some keep last typed key for a second. Some use a
combination of those. Real mess if you ask me.
iPhone solution
iPhone has an interesting solution (or solution attempt) to this
problem. It keeps the last typed character for a short time and then
converts it to bullet. It might help you during typing but it doesn't
resolve "shoulder surfing" problem that is present.
Some other solutions?
Unfortunately and fortunately
