Josh Junon@bad-at-computer.bsky.social · 11mo agoYep, I've been pwned. 2FA reset email, looked very legitimate. Only NPM affected. I've sent an email off to @npmjs.bsky.social to see if I can get access again. Sorry everyone, I should have paid more attention. Not like me; have had a stressful week. Will work to get this cleaned up.
