The field is somewhat redundant because the signin flow gets the user identifier (gaia ID) by other means. However, to prevent bugs that can lead to mixing up encryption keys across users, this patch bundles the gaia ID together with encryption keys and verifies the integrity of the information when the signin procedure completes, prior to the actual processing of the keys.
