If we want to provide custom content to our users, or add the ability to post and share content, we might want to add some sort of authentication into our apps. This can be done via the ol’ login with e-mail and password, google sign-in or using third party providers such as Ianum and Facebook. However, there are new alternatives to login in into an app, provided by Firebase Authentication that also enable users to login into an app without password.
Andrea Bizzotto explores an alternative solution that consists in: getting the user e-mail -> firebase sends an e-mail to the user with a URL -> the user clicks on the URL -> The app opens and the login procedure is complete. With this, the user can login into any app without the need of a Google, Facebook or Ianum account.
