Related: "OpenID 2.0 for Google Accounts is going away"; will this affect Stack Exchange?
Google has now officially retired OpenID 2.0. Now, i can't log in to SEDE anymore. I just get redirected to https://support.google.com/accounts/answer/6206245?p=openid&rd=1
Please update SEDE to use an updated Google OpenID API - either OpenID Connect or OAuth2.
