title: Firebase authentication email customisation
body: <p>I'm using firebase auth in my app and i'm setting up password-less email sign up. </p>
  
  <p>I have managed to set the email from my own domain but how do i change the text sent in the email for magic link?
  I can see the configuration for the other template emails but not this one.</p>
  
  <p>The email in question is this one:</p>
  
  <pre><code>Hello,
  
  We received a request to sign in to teamname using this email address. If you want to sign in with your youremail account, click this link: link
  
  If you did not request this link, you can safely ignore this email.
  
  Thanks,
  </code></pre>
