阻止第三方Cookie时，Google Signin成功功能不起作用

Question

I am building AngularJS application that uses basic Google Signin process https://developers.google.com/identity/sign-in/web/ .

Everything works fine, I can sign in as a google user except I have one issue when I disable third party cookies.

When third party cookies are disabled on browser like this (Chrome) content settings google sign in process does nothing.

More precisely I have a function that triggers on onsuccess event for google button but does nothing. Also I am not possible to catch an error so I can't workaround after this.

One thing that is happening also is that on loading google meta data when third-party cookies are disabled it raises an error

Uncaught SecurityError: Failed to read the 'localStorage' property from 'Window': Access is denied for this document

It seems that google does everything fine like it should be on success but doesn't execute the code that is in that onsuccess function.

I tried everything and even on google developers site on Integrate Sign-in page when I click on sample sign in button it happens the same:

• If I enable cookies it returns to me "signed in as: MyName"
• If I disable cookies it returns nothing to me

The overall question is, is there a way to catch this error and work around this and not having google executes everything like it is ok and doesn't execute code that is in onsuccess function?

Answer 1

Users who have third party cookies disabled cannot access pop-up Google sign-in .

This is a deal breaker for us, as third party cookies are a recommended privacy practice (and the default in Safari). Instead it's necessary to use the Google API to generate an authentication URL , after which you'll get a callback with a token.
