Is it possible to create an app when a button is clicked the login details will be auto filled like for Facebook, gmail, etc…
No not firebase authentication. Normal website
yes it can be done but its highly recommended not to do so because you are storing user credentials in app which is hackable.
you want to store only for your website or other websites.
For your website simple is to use cookies
