title: Verifying that the account belongs to the person that claims
body: <p><strong>Context</strong></p>
  
  <p>Sign-up form and one of the fields is Instagram account
  When the user will finish sing up, there's a link to the person's Insta account
  (No integrations)</p>
  
  <p><strong>Goal</strong></p>
  
  <p>I want to make sure the user can only sign up with his own Instagram,
  much like e-mail verification</p>
  
  <p><strong>My thoughts</strong></p>
  
  <p>I took a look at the Instagram API documentation and didn't find an option for it. Any thoughts about how to do that? </p>
  
  <p>There would be an option to use the Insta auth basic, allow the user to sign-up via Instagram. Although this seems to be a proper overkill and it's getting deprecated anyways.</p>
