Just doing my undue diligence.

ISP vet (was AS7782, now AS8047), password cracker (Team Hashcat), security demi-boffin, YubiKey stan, public-interest technologist, AK license plate geek. Husband to a philosopher, father to a llama fanatic. Views his.

Day job: Enterprise Security Architect for an Alaskan ISP.

Obsessed with security keys:
techsolvency.com/mfa/security-keys

My 2017 talk "Password Cracking 201: Beyond the Basics":
youtube.com/watch?v=-uiMQGICeQY&t=20260s

Followed = probably stole you from someone I respect.

Blocked inadvertently? Ask!

Am I following a dirtbag? Tell me!

Suggestions welcome!

Photo: White 50-ish man w/big forehead, short beard, & glasses, grinning by a display of Alaskan license plates.

Boosts not about security ... usually are.

Banner: 5 rows of security keys in a wall case.

P.S. I hate advance-fee scammers w/heat of 400B suns
