> What is the life of a yubikey? Do they degrade over time horizons?
Not that I could see over about 4 years. I've been using one YubiKey (USB-A) for over four years now and a second one (USB-C) for over two. Each has been carried with my keys for at least two years.
But the right approach anyway is to use this excellent tutorial: https://github.com/drduh/YubiKey-Guide and generate your keys yourself, storing a backup in a secure location. This is what I do — so even if my keys get completely destroyed, it will be possible to recreate them from backup.
