title: Is there an accepted way to use API keys for authentication in Flask?
body: <p>I have a small API that I'd like to add authentication to.  I'd like to be able to generate API keys for API consumers; the consumers can then use include the keys with their requests requests.</p>
  
  <p>Is there a Flask library which does something like this?  Or is there a typical way to do it?  I did a search and I only really came upon <a href="https://coderwall.com/p/4qickw">this</a>, which doesn't really go very much in depth.  I'm looking for a library if there is one.</p>
