I don't know who needs to hear this, but put an AirTag on that key ring of FIDO2 security keys you have.
@JefTek also, never have just one FIDO2 key. Keep a backup key in a safe place, and only take it out when provisioning accounts for MFA.
@kcappleguy Whoever decided to make some FIDO2 keys silver and shiny and attach them to a jangling keychain that delighted my cat to take it from my desk and hide it who knows where......learned a lesson indeed :)
@DaveMWilburn Setup 2 FIDO2 keys on your Passkey ecosystem of choice, then store them in safe place. Use Passkeys as your daily use credentials. FIDO2 bootstrapping + Mobile Passkeys = best of both worlds
