it's mainly focused on storing the master key password. So basically you would print that out on a paper and store it inside, as well as storing it in a word document and put it on the USB drive. Nothing technical at all just a specific place to store your password.
The active and posting key I would still store somewhere where it's accessible on a daily basis. The master password Is not something you need till you need it, but when you do it's good to have it stored both digitally and the old fashioned way on paper in my opinion.
You have been on the platform for a long time, do you have some good advice ?
