So Lemmy's 2FA does not provide a means of validating 2FA setup before enabling it. This can quickly lead to a situation where you get locked out of your account. So, read the link.
And if 2FA still breaks on you, ask an Admin to disable 2FA on your account.
Recognition that animal testing is actually pretty fucked up would be a good start toward funding research into alternatives, such as biological computer simulations.
We can simulate complex/chaotic systems, like weather, in nearly real-time, so biosim research is mainly a funding and staffing problem at this point.
Probably we'll still need animal testing for the final phase before human trials, but we can at least reduce the need for it to bare minimums.
