title: Pros and cons of using this minimalist system?
body: <p>I'm trying to create a very simple login system for my app. Would it be possible to have a minimalist system for login/signup where there are fields for the username and password and then allow them choose between logging in or signing up with those fields? Versus having them choose initially between logging in or signing up and then going through a different process depending on which option they chose?</p>
  
  <p>A simple login system similar I'm talking about was used in the Yo app. The difference is that they separated their login and sign up but the fields that the user has to enter are the same, so I was wondering if I could simplify the process further.</p>
  
  <p>I was wondering what the pros and cons of using this sort of system were, and if this is a good option for my simple app.</p>
