This is actually a pattern I've seen on many (native) mobile apps I think that evernote might do it (?) I've never seen it shown by default, but requires an explicit user action to show.

You see this on website too, especially ones with an accessibility focus, elderly people often have trouble typing passwords because they can't visually verify they've typed the right thing when the password is obscured. 

I think this is a great pattern for a system where people are accessing it from their own devices (rather than public ones)

I downloaded the Android app for Wikipedia and had a play around with
it. One particular bit gave me a bad experience/first impression, so
here's some feedback for you.

I was completely puzzled yesterday when I tried logging into the
Wikipedia app for the first time. I added my login, password and then
hit the checkbox to remember my login.. only then to realise my
password was not visible in plaintext and that the label did not say
remember my login [1]. Now this password I use on a couple of sites (I
know that's bad but it's the case here). I never write it anywhere,
it's engrained in my memory. So to see it there in plain text freaked
me out and I was suddenly weary that I was in a public space where
people could see over my shoulder and to be honest I felt really
violated. I've now changed that password.

This was a really nasty experience for me. I'm trained to check those
remember login checkboxes, just as on a signup form I'm trained to
uncheck the add me to your mailing list box (which some forms abuse)
and check the i agree to terms and conditions boxes. I never read the
label.

I don't really get the need for such a feature though. No login forms
on the web in website or app form that I know of have such an option
as `show password` (please point me at some if they exist). It's not
clear to me what this achieves. It doesn't help me remember it for
example... all it seems to achieve is to give the impression that the
password is not important and can be shared.
