As I noted at the end of my previous piece, Yubico currently has a sale running: 20% off when you buy two YubiKey Security Keys: $46.40 instead of $58. The sale ends August 16, 2026—today, as I publish this. (The discount does not apply to any quantity above two, and applies only to the Security Key Series.) If you’re considering protecting your accounts with a physical security key for two-factor authentication, grab a pair. They work great with Apple’s Security Keys implementation. I already have two YubiKey 5 Series devices, and my wife and I each purchased two of the Security Key Series.
