title: How to allow empty passwords in ASP.Net MVC 5 with individual user accounts
body: <p>This might seem like a weird question, but I have a low security project that will only have a handful of users. Most of the users would definitely prefer not having to input password when signing in. I would like the ability to use password if wanted though. Similar to the way Windows 10 allows logging in without a password.</p>
  <p>Any help with this would be great! I have currently removed the <code>required</code> annotation on the password property inside <code>AccountViewModels</code> but I am stuck at the point where it is throwing an error after I submit the register form.

  <p>If anyone has ever done this before, I would love a few pointers.</p>
