Any content encrypted by info@lockmagic.com can be accessed by lockmagic@gmail.com and support@lockmagic.com without having to authorize these two accounts. Trust relationship is one-way and in order to establish trust for all accounts, you must login to lockmagic with each account and add the other accounts you wish to trust.
