I was thinking the timing for all authentication paths, successful and failure, needed to be indistinguishable, but I see now that that's not the case. The successful path can be as fast as possible, but all *failure* paths need to be indistinguishable so as to avoid leaking. Now I get it. Sorry for being slow on this. Thank you for your continued explanation and patience. > Is there a reason that "fast authentication denial" is desirable? For me, no. Best, Lewis
