I was team SPAKE2 based PAKEs, but I now know that SPEKE based PAKEs are better. P.S. SPAKE2 is a balanced PAKE vs augmented PAKE (or unbalanced PAKE) like OPAQUE and SPAKE2+ (and SPAKE2+EE).

> Isn't this trivially possible in Cryptocat for anyone who controls the server? Yes this is a known bug since August 2013. When I found it and reported it. This was "patched" but if Mallory controls the server it is still
