title: Authenticating Laravel's API with Sanctum and Firebase Authentication
body: <p>I am using Laravel to create an API.<br />
  I am also using Firebase Authentication for user authentication.</p>
  <p>I would like to treat the &quot;idToken&quot; issued by Firebase Authentication as a Bearer Token.<br />
  And I would like to confirm this with Sanctum.</p>
  <p>Since idToken is used for Bearer Token, no database is used.<br />
  However, there are only samples that allow the users table to have a token.</p>
  <p>I simply want to verify the Bearer token using Firebase Authentication's verifyIdToken method to verify the token.<br />
  How can I use Sanctum to handle this kind of case?</p>
  <p>I would appreciate it if you could tell me about it.</p>
  <p>P.S.
  My native language is not English, so I apologize for my poor English.</p>
