If you have more digital assets which you own, you can also consider getting specific hardware designed to protect digital information. A perfect example would be a hard drive using complete encryption — without the proper password, nothing can be retrieved, and your assets are perfectly safe. You just have to be sure that your executor does know where the storage device is, and has all the keys to unlock it. The cons are simple: the locker must be physically accessible, undamaged (when sometimes defects appear over time, rendering your assets inaccessible), and you will have to physically access it to update it.
