WhatsApp has this scheme. And to my knowledge, never had there been a report of verification failing.

- vinay_ys 3y agoI get the warning "your contact key has changed.." all the time with various contacts on WhatsApp. What am I supposed to do? there's no clear next steps to debug / report of suspicious activity. In such cases, users get trained to become complacent of such warnings.
