License Activation

[YONG HYUN YU]

Hello. I bought 5 licenses for 6 years. If I register all of these activation codes in my account on the same day, can I continue using them for 6 years? I am concerned about the loss, so I am planning to register in advance and use 5 devices each for 6 years. What if, I'm late to find out that it isn't, and I've already registered all of them, is there any way to recover? Register for an account only and haven't used it yet.
