Mac constantly asking for Facebook password
After changing my Facebook password, I keep getting a notification from the system (NOT the browser) "Facebook Password Required: Enter your password in Internet Accounts." In System Preferences -> Internet Accounts, clicking on Facebook gives me the message "Can't connect to the account Facebook. Enter the password for user [MY NAME]" When I put the password in, it says "Unable to verify account name or password."
The password is correct. I can log in to facebook just fine through the browser or on my phone, but after I changed the password in the browser, it broke the integration with mac apps through the system (for instance, I cannot post a photo to facebook from the photos app anymore). I've tried deleting the facebook account entirely from System Preferences and making a new one, but the same problem occurs.
I'm on a Macbook Air running the current version of High Sierra.
