The subject matter described herein can be embodied in a computer-readable medium storing instructions that cause one or more processors to perform operations including receiving, from a client device associated with a user account of a first user, a request to grant a second user access to a key associated with a credential. The credential is associated with the user account of the first user, the request includes an address of the second user, and the key permits access to a resource. The operations include accessing, at a server, a second user account based on the address of the second user, and associating, by the server, the key with the second user account, such that the second user is enabled to access the resource. The operations further include communicating, to the address of the second user, a message indicating that the second user account has been associated with the key.
