Firebase Authentication

Google · Firebase Documentation Freemium Beginner

Firebase Auth is the battle tested default for mobile first and Google Cloud based apps, with a very generous free tier. It handles email, phone, and social sign in without you owning any of the security machinery. Consider it if you are building mobile heavy or already live in the Google ecosystem.

  • Strong choice for mobile first apps and Google Cloud stacks
  • Generous free tier easily covers an MVP's user counts
  • Email, phone, and social login come ready without custom work
