DID - Passwordless Authentication
DID is a piece of software that enables passwordless authentication. It does this by offering magic sign-in links by email but also with device authentication.
This is achieved using public key cryptography. Later on in the project, we also devised and implemented 'magic invite links' whereby magic links are sent to new users as an invite for frictionless onboarding.
Peter Saxton and I worked on DID together during 2019 and 2020. We applied to YCombinator with the idea and were accepted.
If you would like to find out more about how DID works, I wrote an article on the subject.
