How AI Agents Will Break Passkeys — And 3 Ways To Fix Them

Major tech companies are pushing passkeys as the password replacement, using cryptography to eliminate phishing and authentication headaches. However, as businesses integrate AI agents into workflows, passkeys create a critical vulnerability since agents can't use biometrics or personal devices, forcing users to share full credentials rather than limited access. This gives AI agents excessive privileges to pull data at machine speed, spawn sub-agents, and potentially be hijacked by attackers, recreating the password reuse problem passkeys were designed to solve but at a much more dangerous scale.
