• h.googleplusauth.login_button(client_id, scope=None, data_cookiepolicy=None, img_btn_login=None, remember=None)

  Places a login/registration button, automatically creates a new user if he never logged with google, otherwise simply logs him in.

  The client_id parameter is YOUR_CLIENT_ID.apps.googleusercontent.com

  The scope parameter is the permissions that the application will ask to google. By default those are only https://www.googleapis.com/auth/userinfo.email. For more scope: https://developers.google.com/oauthplayground/

  The data_cookiepolicy parameter indicate the domains for which to create sign-in cookies.

  The img_btn_login parameter indicate the button image url.

  The remember parameter can be used to log the user with an expiration date instead of using a session cookie, so that the session can last longer than the browser tab life.

This is the html of the button, if you want customize the button style:

<div id="button-container">
    <div id="google-login-button" style="cursor: pointer;" onclick="perform_google_login()">
        <img id="img-login" src='%(img_btn_login)s' alt='Google Login' />
