Implement “Sign in with Google” (FedCM Popup) on terapiaact.com.br

Hello!

I can implement exactly what you described for terapiaact.com.br using Google Identity Services with FedCM and integrate it cleanly into your existing WordPress + MySQL setup.

What I will do technically

1. Google Identity Services (FedCM) setup

Configure a new OAuth 2.0 Client in Google Cloud Console for your domain.
…
Implement the new Google Identity Services JS (One Tap / FedCM popup) so that:

The popup automatically shows for users already signed into Google.

One-click login works exactly like in your reference UI.


Make sure it respects your domain, HTTPS, and browser FedCM requirements.



2. WordPress integration

Implement a small custom plugin or theme integration (no core hacks) that:

Handles the ID token from Google on the server side (PHP).

Verifies the token via Google (audience, issuer, expiry).

Extracts google_id, name, email, avatar_url securely.




3. Database layer

Use your existing MySQL database and create a dedicated table, for example:

ta_google_users

id (primary key, auto increment)

google_id (unique)

name

email

avatar_url

created_at

last_login_at


On login:

If the Google user is new → insert a record.

If the user exists → update last_login_at and any changed fields (name, avatar).




4. Authentication / session handling

Either:

Map Google users to native WordPress users (wp_users) and log them in via WordPress auth,
or, if you prefer:

Keep a separate session mechanism for ta_google_users and use it for gated areas.


Protect against CSRF and replay attacks, use nonces and secure cookies.



5. Security & best practices

Use prepared statements / $wpdb for all DB operations.

Validate and sanitize all incoming data.

Limit the integration to your domain and correct client_id.

Make the solution maintainable: clear code structure, comments, and configuration options.

If you’d like, I can also:

Add a small admin page in WP to view/filter Google users from ta_google_users.

Log basic auth events (new user, login, error) for debugging.


I’m ready to start as soon as you provide:

Access to a staging or dev environment,

Your Google Cloud client credentials,

And any preferences about mapping to WordPress users vs dedicated table only.

Curious about elevating your users' experience while ensuring secure authentication? Implementing “Sign in with Google” using FedCM popup will streamline access to terapiaact.com.br. I’ve successfully integrated similar identity services and will seamlessly incorporate this feature into your WordPress setup, securing user data in a dedicated MySQL table. With expertise in merging UI/UX with robust backend solutions, my approach ensures both immediate and long-term benefits. Collaborate with me to enhance engagement and build a smooth, secure user login experience.

Hi Maksym Merzhvynskyi,
I can do it in 1 hour.

Best regards.
