Facetime suddenly requiring sign-in, which fails

[MacBiter]

After a restart yesterday due to a Bluetooth problem, I suddenly found I couldn't Facetime (as I do nearly every day) without a sign-in. That alone didn't bother me - I entered my Apple ID, password + 2FA digits, but got the message "The server encountered an error processing registration...", even after restoring every component with yesterday's date containing "facetime" via Time Machine, from 3 days ago.

How do I get FT back to how it was?

Double-check the Date & Time setting in Mavericks. It may not be automatically syncing with a time server.

It's not that - I've just seen another post on this very topic. I fear FT is now broken in Mavericks but only shows the error after a restart and request to sign in.

No, I couldn't use FT at all without signing in.

there is a fix for it. the issue here is that the endpoint seems to be blocking requests with plain usernames and passwords. 10.11 and later use the grandslam authentication system, which sends a hashed version of the password. the server gives back a username and password token that expires after 5 minutes. new os x uses these credentials to log in.
