Keychain syncing

A device comprising:

• a memory configured to store a keychain;
• and
• at least one processor configured to:
• receive a modification to the keychain;
• for each respective other device in a group of devices, determine whether the keychain matches a respective other keychain on the respective other device, wherein each device in the group of devices having been registered into the group through a user account;
• generate a respective update request for each respective other device in the group of devices for which the other respective other keychain does not match the keychain, the respective update request indicating one or more modifications to be made to the respective other keychain;
• establish a respective secure channel between the device and each respective other device for which the respective update request was generated, each respective secure channel being established using a respective key corresponding to, and received from each respective other device;
• and
• transmit, to each respective other device over the respective secure channel and through a network, the respective update request for each respective other device.

A computer program product comprising code stored on a non-transitory machine-readable medium, the code, when executed by one or more processors, causes the one or more processors to perform operations, and the code comprising:

• code to receive a modification to a keychain stored on a first device in a group of devices, each device having been registered into the group through a user account;
• code to, for each respective other device in the group of devices, determine whether the keychain of the first device matches a respective other keychain on the respective other device;
• code to generate a respective update request for each respective other device in the group of devices for which the other respective other keychain does not match the keychain of the first device, the respective update request indicating one or more modifications to be made to the respective other keychain;
• code to encrypt, by the first device and for each respective other device for which the respective update request was generated and using a respective encryption key that specifically corresponds to, and was received from, the respective other device, the respective update request;
• and
• code to transmit, by the first device to each respective other device through a network, the respective encrypted update request for each respective other device.
