Link User Identities¶
MongoDB Realm provides multiple ways for users to log into your application. Because each method of authentication corresponds to a unique user identity, Realm lets you merge multiple identities belonging to a single user into one user identity.
Consider an application that enables users to authenticate via anonymous authentication. When that user decides to create a full account with an SSO provider or email/password authentication, you need some way of persisting the user's original anonymous identity with their new permanent identity.
You can link identities using the
User object of a logged-in User.
