Google Sign-In
Your users already have a Google account. Let them use it.
Half the internet signs in with Google now, because it's the account everyone already has open. Adding it to your site is one button for the user and a surprising amount of engineering behind it — consent screens, token verification, One Tap, account linking. We do the engineering; your users get the button.
One button, a lot of moving parts.
From the outside, 'Sign in with Google' is a button. Behind it: an OAuth application registered and configured, a consent screen that must pass Google's verification review, scopes requested narrowly enough to avoid the scary warning screens, ID tokens that must be verified server-side — never trusted from the browser — and a session layer that keeps users signed in without keeping them exposed.
Skipping any of these produces the classic failure modes: the 'unverified app' warning that scares customers off, logins that work in testing and fail in production, or — worst — token handling that trusts the client and turns your login into an open door. We've built this flow enough times to walk it blindfolded, which is exactly why you shouldn't have to.
One Tap: the highest-converting login on the web.
Google One Tap shows returning visitors a single prompt — their own face, one tap, signed in. No form, no typing, no decision fatigue. For sites that live on repeat visits it's the difference between a member who returns and a visitor who re-registers a duplicate account.
We implement One Tap where it earns its place and suppress it where it annoys — there is a version of this feature that helps and a version that harasses, and the difference is configuration judgment.
Workspace accounts make this a B2B feature too.
Every business on Google Workspace signs in with Google by default. If you sell to businesses, 'Sign in with Google' is quietly your enterprise SSO starter kit — domain-restricted access, no password policy meetings, and IT departments that already trust the flow. We've wired it into TeamAIOps and MEP AI Pro, where business customers expect exactly this.
Existing email users keep working, of course — the linking layer connects a Google sign-in to the right existing account instead of minting a duplicate.
What a proper Google integration includes.
The checklist that separates 'the button appears' from 'the button converts.'
Consent screen verification
Configured and shepherded through Google's review, so users never meet the 'unverified app' warning.
One Tap
The single-prompt return experience, tuned to help rather than harass.
Server-side token checks
ID tokens verified where they can't be forged. The browser is never the authority.
Narrow scopes
Only the data the feature needs — which keeps consent screens friendly and audits short.
Account linking
Google sign-ins matched to existing email accounts by verified address. No duplicates.
Workspace-ready
Domain-aware sign-in for B2B — the enterprise SSO conversation, skipped.
Questions we hear a lot.
How long does Google Sign-In take to add?
A clean stack takes days. The variable is Google's consent-screen review when your app requests sensitive scopes — we configure to avoid that lane where possible, and manage the review when it isn't. You get the honest timeline with the quote.
Will existing email/password users be affected?
No. Their logins keep working; Google becomes an additional door. When someone with an existing account signs in with Google using the same email, the linking layer connects them to their history instead of creating a twin.
What's the 'unverified app' warning and will my users see it?
It's what Google shows when an app's consent screen hasn't passed review for the scopes it requests. Users see a full-screen warning and most turn back. We configure scopes and verification so your users never meet it.
Do you handle the Google Cloud setup?
All of it — project, OAuth credentials, consent screen, authorized domains, and the production/test separation that prevents the works-in-dev-fails-in-prod surprise.
Can this work with my WordPress site?
Yes — we integrate Google Sign-In on WordPress, custom stacks, and everything between. On WordPress it's done as a proper integration, not a fifteen-permission plugin from the marketplace roulette.
