I need a word. A verb, ideally a monosyllable, for the experience of being blocked or hindered by a 2-factor authentication system.

This is often ambiguously abbreviated to TFA but I prefer 2FA, but neither's easily _said_. If it was two _way_ authentication, TWA, I could say "hang on a second, I've just been TWAtted."

Something like that. Sounding like an Ango-Saxon obscenity a bonus.
