Lessons in safe identity linking

Identity linking consolidates duplicate accounts with their own authentication credentials into a single account, which can be complex due to email and domain verification considerations. WorkOS handles these complexities and provides secure identity linking by default. The process involves associating user profiles from different authentication providers with a unique user in the application. Email verification is commonly used for this purpose, but there are more frictionless ways depending on the identity provider. In enterprise contexts, domain capture can remove the need to verify emails within that domain once ownership of the domain has been verified by IT admins. Understanding and accounting for the behavior of different authentication providers when linking identities is crucial for maintaining security.
