Subject: Added option to use the immutable identifier Google User ID
X-Git-Url: https://git.parisson.com/?a=commitdiff_plain;h=78b59af49fae580dd011543ab64c1b99b6d43b2d;p=django-social-auth.git

Added option to use the immutable identifier Google User ID

Setting GOOGLE_OAUTH2_USE_UNIQUE_USER_ID to True for the
Google OAuth 2.0 Backend makes use of the id fields in the
returned Google profile information instead of the mutable email.
