You don't need to do a thing. As long as you have installed the True Key app on all your devices, your information will be synced automatically and securely so you always have your Logins, Safe Notes and Wallet data on hand.
Plus, any time you change or otherwise modify any of your information in the app, those changes will also be synced across your devices. It even works across browsers! For mobile phones & tablets, get the True Key app in the iTunes & Google Play stores.
