Break my Passwordless Recovery Protocol and get a 50€ Bug-Bounty

I designed a passwordless recovery protocol using trusted friends and a server-side second factor for my privacy-focused messaging app twonly. To ensure its security before release, I am launching a 50€ bug bounty challenge for anyone who can find a vulnerability in the protocol.
