    • There is provided a method comprising: receiving, at a first peer device, a modification to a keychain stored on the first peer device in a group of peer devices, each peer device having been registered into the group through a user account; for each respective other peer device in the group of peer devices, determining (1220), by the first peer device, whether the keychain of the first peer device matches a respective other keychain on the respective other peer device; generating (1230), by the first peer device, a respective update request for each respective other peer device in the group of peer devices for which the other respective other keychain does not match the keychain of the first peer device, the respective update request indicating one or more modifications to be made to the respective other keychain; encrypting (1240), by the first peer device and for each respective other peer 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 peer device, the respective update request; and transmitting (1250), by the first peer device and to each respective other peer device through a network, the respective encrypted update request for each respective other peer device.
