Should I Add Google Login or Just Email and Password for My Beta?

6 min read

For most first betas, the fastest safe answer is: add "Sign in with Google" and skip building your own password flow. Social login hands off the hardest, riskiest parts of authentication to Google, and it removes a pile of screens you would otherwise have to build and test before launch. If your users are consumers or developers, one Google (or GitHub) button is usually enough to go live with.

Why this even comes up

Your AI agent will build whatever you name. Ask it for "a login page" and you get email and password: two fields, a signup form, a login form. What it does not build unless you ask are the four things that make passwords real, password reset, email verification, secure password storage, and rate limiting on the login form. The demo works because you are the only user and you remember your password. The gaps only show up when a stranger forgets theirs, or tries to guess someone else's.

Social login sidesteps most of that. When a user signs in with Google, Google handles the password, the reset, the verification, and the brute-force protection. Your app just receives a verified identity.

The honest tradeoffs

Sign in with Google / GitHub

  • Removes password storage, reset, and verification from your plate entirely.
  • Emails arrive already verified, so you know the address is real.
  • One click for the user, which lifts signup completion.
  • Downside: it depends on the user having that kind of account, and it needs a short setup step in Google Cloud (an OAuth consent screen and a client ID).

Email and password

  • Works for every user, no third-party account required.
  • Familiar and fully under your control.
  • Downside: you now own reset flows, verification, secure hashing, and login rate limiting. That is four features to build and test, not one.

How to decide in five minutes

  1. Who are your beta users? Consumers and developers almost all have Google or GitHub accounts. Social login fits. If you are selling to businesses on locked-down corporate email, some staff cannot use personal Google, so keep email/password too.
  2. How fast do you need to launch? If the answer is "this week," one Google button is the shorter, safer path.
  3. Check what your platform already gives you. Supabase, Firebase, Clerk, and Auth0 all ship Google and GitHub providers you enable with a toggle and a client ID. You are turning on a feature, not writing an OAuth flow by hand.

The fix: ship one, cleanly

  1. Pick your primary method. For most consumer or developer betas, make "Sign in with Google" the main button.
  2. Enable it in your auth provider. In Supabase: Authentication, Providers, Google. In Firebase: Authentication, Sign-in method, Google. Paste the client ID and secret from Google Cloud and add your live domain to the allowed redirect URLs.
  3. Test the real redirect, not localhost. Deploy, then sign in from the deployed URL. The most common launch bug is a redirect URI that works locally and fails in production because the live domain was never added.
  4. If you keep email/password too, finish it properly. That means password reset and email verification. Half a password system is worse than none.

The trap to avoid

Do not build your own from-scratch OAuth flow, hand-rolling token exchange and storing Google's tokens yourself. It is fiddly, easy to get wrong, and entirely unnecessary when your auth provider already does it. And do not offer five login buttons on day one. Every method you add is another flow to test. One that works beats three that are half-wired.

Where this fits

Picking a login method is a small decision that quietly determines how much auth you have to get right before real users arrive. The free Readiness Report checks your actual project for the gaps this choice leaves behind, an unverified email path, a missing reset flow, a login form with no rate limiting, so you know what is still open. If you would rather have those fixes handed to you in order, that is what the Finishing Pass is for. If your beta handles anything sensitive, it is also worth reading whether you need two-factor authentication yet.
