How do you ensure security when storing your BTC?

With BTC being so valuable, I’ve been thinking a lot about security lately. I use a hardware wallet for storage, but I’m always looking for ways to add an extra layer of protection. I recently came across Orb, which uses iris scanning for identity verification. Seems like an interesting tech to integrate with wallets and exchanges to make sure only the real owner can access their funds.

Anyone here use any similar tech to protect their BTC, or do you rely on traditional methods like 2FA?
