    'allauth.socialaccount.providers.google',
]
...


LOGIN_REDIRECT_URL = "/"
LOGOUT_REDIRECT_URL = "/"

SOCIALACCOUNT_LOGIN_ON_GET = True
ACCOUNT_LOGOUT_ON_GET = True

SOCIALACCOUNT_PROVIDERS = {
    "google": {
        "APP": {
            "client_id": GOOGLE_CLIENT_ID,
            "secret": GOOGLE_CLIENT_SECRET,
