title: How to update new API key on current firebase project
body: <p>For some reason, my firebase project apikey associate with database changed. I can still create another api key, update into the application.</p>
  
  <p>But when user try to reset password, the link use the old key and lead to "Your request to reset your password has expired or the link has already been used" (I think I read this problem somewhere and now I found the reason).</p>
  
  <p>Is there anyway to update new api key for an existing firebase project?</p>
  
  <p>Thank you</p>
