In one implementation, a server system receives, from a device of a user, a request to add a credential issued by an organization and authentication information that has been authorized, independently of the server system, by the organization that issued the credential. The server system identifies the organization related to the request to add the credential and identifies communication information established for the organization. The server system provides, using the communication information and to a system operated by the organization, the authentication information and receives, using the communication information and from the system operated by the organization, credential information for the user. The server system adds one or more credentials to an account of the user based on the received credential information.
