Validating email address php
The documentation found in Using OAuth 2.0 to Access Google APIs also applies to this service.If you want to explore this protocol interactively, we recommend the Google OAuth 2.0 Playground.Make sure you set up your app in the API Console to enable it to use these protocols and authenticate your users.
(This generic dialog was generated using the Google OAuth 2.0 Playground, so it does not include branding information that would be set in the API Console.) Google and third parties provide libraries that you can use to take care of many of the implementation details of authenticating users and gaining access to Google APIs.
The user consent screen also presents branding information such as your product name, logo, and a homepage URL.
You control the branding information in the API Console.
If your server passes the ID token to other components of your app, it is extremely important that the other components validate the token before using it.
Since most API libraries combine the validation with the work of decoding the base64 and parsing the JSON, you will probably end up validating the token anyway as you access the fields in the ID token.
This can be used as an alternate mechanism to protect against cross-site request forgery attacks, but if you follow Step 1 and Step 3 it is not necessary to verify the access token. This claim is only needed when the party requesting the ID token is not the same as the audience of the ID token.
