Google SignIn user authentication opening in Popup window, need to open in same Tab itself using OAuth 2.0

Question

I am using OAuth 2.0 for google SingIn, it is opening a popup window for user authentication but i want to open in same tab itself, please help me. Thanks in advance.

Answer 1

The popup window opens if you use Google Sign-In JavaScript library. You have to use server side api client libraries to authenticate / authorize without a popup. https://developers.google.com/identity/protocols/OAuth2WebServer

Answer 2

You can use ux_mode: redirect to change Google to Redirect mode which will open in the same tab instead of in a popup.
Ref: https://developers.google.com/identity/sign-in/web/reference#gapiauth2clientconfig

Then on your redirect landing page, use auth2.currentUser.get() to retrieve the signed in Google User object.
