Experience
Children's Spy Agency
https://www.csa.world/Children's Spy Agency is a mobile app that teaches kids (5+ years old) critical thinking, computer science, and creativity in a playful way.
Since kids usually don't have their own email accounts and may have trouble creating and remembering strong passwords, the app has an unusual way of user authentication. Kids sign up with their parent's email address (or guardian) but log in using their nicknames and emoji password.
I was hired to extend the Firebase authentication and database to allow this unusual way of user authentication.
