SecureLogin Authentication Protocol 1.0
I like the idea, but the master password scares me a bit. So if I accidentally type my master password into Slack one day (not that that has ever happened), it seems anyone who saw it would then immediately be able to log into every website using SecureLogin as me.The README addresses a concern about "Master password is single point of failure in this system", but it talks about the case of a user forgetting it, not accidentally disclosing it.
