VERDICT

Should I use Yubico?

YubiKey — strong two-factor authentication - yubico.com

Worth it. Buy if you're protecting high-value or regulated accounts — it's the category standard at a low one-time price. Skip if you just need everyday MFA; free authenticator apps or passkeys cover most casual users.

Confidence

High. Based on 20+ public sources. Dollar prices marked 'Guess' — evidence snippets discussed price but showed no exact figures.
