if you choose the audio captcha option you get a json error of "access denied".
really starting believe the agenda was to destroy the platform completely. Because it's becoming more trouble than it's worth.
And that was this week when trying to login on a new browser on a new laptop, but couldn't provide the 2fa from my authenticator app because I forgot to setup a replacement authenticator token when I changed phones a couple years ago
And the fix was simple: disable 2fa (from a browser already logged in), then enable 2fa, add it to my authenticator app, and go about my day
Took about 30 seconds
I cannot recall having gotten a captcha with Twitter (or, now, X) since I first signed up in '09
Are you sure you do no have sandboxing or javascript blocking or the like enabled in your browser that you are trying to sign-on in?
