That's insightful. So you shouldn't only reset your passwords, but your TOTP setup too (if you set it up in this period).

I think it's a flaw of TOTP though. The client secret should be client generated and should never leave the device.



Yes, unfortunately both the client and server need to have that shared private key to generate the same codes.

Transmitting the key over a 'secondary' channel would have protected people here.

It begs the question of whether or not TOTP is really 2FA if it is setup using a single channel of communication.
