Why can't I log into Buzzfeed with my Google plus account?

You may be unable to log into BuzzFeed with your google Plus account because google Plus was officially shut down for consumers in April 2019, leading to the discontinuation of its login services. If BuzzFeed previously supported google Plus logins, they would have since updated their authentication options to exclude it. You can try logging in using a different method, such as your email or another social media account.
