I hate to be that guy, but why is something as trivial and inflexible as this being voted up?<p>It's the schema for the user accounts and logins for a specific application, but without the actual application or documentation that would explain what the idea of each table and column is?<p>Is this meant as a "Here's how you could model a database for doing this", why is it lacking any explanations on how to use it, justifications for the choices, or examples on how the UI flow would look like?<p>Why is a user's phone number so important that it's part of this, but not a user's last IP address or time of login?<p>Super confused here.
