Google Apps created for Social Login now need to be verified by Google. Verification is required if your app is marked as Public. Before your consent screen and application are verified by Google, you can still test your application with some limitations, once the limitation is exceeded, users will receive a notification from Google, that the App is not verified and probably isn’t truthful.
So before proceeding, please have a look at the Unverified apps documentation which indicates how unverified apps may behave. If you would like to know more information about the verification it self, please check the OAuth Application Verification FAQ of Google.

- Log in with your Google credentials if you are not logged in
- If you don’t have a project yet, you’ll need to create one. You can do this by clicking on the blue “Create project” button on the right side! ( If you already have a project, click on the name of your project in the dashboard instead, which will bring up a modal and click New Project. )
- Click the Create button.
- Name your project and then click on the Create button again
- Once you have a project, you’ll end up in the dashboard.
- Click on the “Credentials” in the left hand menu to create new API credentials
- Select the OAuth consent screen!
- Enter a name for your App under the “Application name” field, which will appear as the name of the app asking for consent.
- Fill the “Authorized domains” field with your domain name. For example if the URL of your site is http://yoursite.com/ then your domain will be yoursite.com !
- Press “Save” and you will be redirected back to Credentials screen.
- Click the Create credentials button and select “OAuth client ID” from the dropdown.

2. App setup
Once your Google app is ready you’ll need to copy and paste the Client ID and Client Secret to the Google provider’s Settings tab. You can find the information at your Google app’s Settings which you can reach from the left sidebar.
Once your Client ID and Client Secret has been added you need to verify the setup first. This verification helps you identify possible problems with the app.

Username prefix on Register
Whenever a new user registers with their Google account they can get a custom prefix so you can easily identify them.
Fallback username prefix on register
Whenever a new user registers with their Google account and we can not generate a valid username from the first name or last name, a random username will be generated. With this option they can get a custom prefix so you can easily identify them.

Common error messages returned by Google during verification
The redirect URI in the request, https://yoursite.com/wp-login.php?loginSocial=google, (where the yoursite.com is your domain) does not match the ones authorized for the OAuth client.
The problem is that the entered Authorized redirect URIs field is not correct for your app. Check the 15th step of the App setup to fix the problem.
Error: invalid_client The OAuth client was not found.
Request is missing required authentication credential
Error: Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.

403 and 404 error
When your other providers work properly, but your Google provider gives you 403 or 404 error, your server or firewall will most likely have a limitation that prevents accessing to pages with HTTP/HTTPS links in them. For more information please visit our Google 403 and 404 errors documentation.
Frequently Asked Questions
Why am I not logged in automatically after the version 3.0.19?
For a better user experience we modified our Google authentication related codes. So once the user was already logged in with the Google provider and logged out, then the person will have the opportunity to chose a different Google account.
It was a common problem that users logged in with a Google account other then the one they wanted, so they logged out from the site. But from this point, the login happened automatically with the selected account.
Fortunately Google offers an account selector scope, so starting from Nextend Social Login 3.0.19, the account selection box will be offered instead of the autologin. In this way users will be able to choose the account they would like to login with.
