This is a meta issue, so I haven’t followed the template, but I am not sure where else to report it.
I have 2FA enabled on my account. After I submit my password, submitting the 2FA code is rejected with a 429 error, “You’ve performed this action too many times. Please wait 58 seconds before trying again.”
If I wait that long (and make sure the code is still valid), it’s accepted. But it looks like the rate limiting has been set a bit too aggressively.
