Handling Authentication and Identity with Neo4j and Auth0

The author, a Developer Experience Engineer at Neo4j, discusses their experience with handling authentication and identity using Auth0 and Neo4j. They initially used express-openid-connect to add authentication to the GraphAcademy site, which is built in TypeScript and backed by a Neo4j Aura database. However, they encountered issues when multiple users had the same email address but different authentication methods, resulting in separate entities with unique IDs. To handle this, they created a :HAS_ALIAS relationship between the two nodes with the same email address. The author also leveraged the *0..1 technique to unify user enrollments at query time by using variable-length paths and Neo4j's ability to expand relationships. Additionally, they mentioned that Auth0 allows for email verification, which ensures that only verified emails are linked to a user's account. The GraphAcademy site is now able to handle authentication and identity with ease, providing a seamless experience for users.
