Communication between a user and various services (e.g., websites) often involves creating a user profile comprising contact information (e.g., a personal email address) that the service uses to contact the user. However, managing communication may be burdensome and ineffective; the user's privacy may be diminished; and revocation of previously issued permission may be unachievable. Presented herein are techniques for providing a communication manager that establishes relationships with services on behalf of users, and that issues tokens to the services representing such relationships. In order to communicate with the user, the service presents the token to the communication manager, which conditions the authorization of the communication on verification of the current permission of user in the relationship represented by the token, optionally including the communication channel of the user requested by the service. This architecture enables more consistent, convenient, privacy-preserving, and revocable user control of communication permissions with the services. |
