Unable to verify account name or password for Facebook

I have High Sierra 10.13.1 I want to share directly from Photos to Facebook. I keep getting "Unable to verify account name or password." I have changed my password twice and still haven't gotten it. I deleted Facebook from my internet Accounts on System Preferences and when I try to readd , I get the "unable....." What else can I try? I do not have on two-step verification for Facebook. Thanks.
