Is it not possible to store an empty password?

[pqvst]

When trying to store an empty password ("") the following error is returned:

Error: Password is required

This feels weird to me, since an empty password is in many cases a "valid password". So it would be nice to be able to store an empty password so that I know if I've asked the user for a password or not.

I.e. the return value is null if a password hasn't been stored. And the return value is "" if an empty password has been stored.

Why is this not supported? Technical limitation?

I believe that this behaviour is related to this line inside setPassword:

node-keytar/lib/keytar.js

Line 36 in fd66226

checkRequired(password, 'Password')

I'm fine with it checking to avoid sending null or undefined through to the native APIs, but maybe an empty string is fine?

I don't have any strong opinions on this, but feel free to open a PR and we can talk about this further if this is something you still care about.
