it is kinda like "Sign Up With Gmail/Apple/Microslop" you get it, but for matrix

how??, well it is that a bot by the thing sends you a message in matrix (you have to input your username) you get a message that is a riddle for like kids but basically bots (unless it's AI which nobody dares to do) wont solve that easy

and you may self host it

so if you solve it (by entering a message) it you get a link to finsh the sign up/log in i made this idea so nobody has to use email which is controlled by big tech
