AI Generates Predictable Passwords Exposing Security Risk

Irregular, an AI cybersecurity firm, found that ChatGPT, Claude, and Gemini produced repetitive, predictable passwords in tests reported Feb. 26, 2026. Claude reused one password 10 times among 50 outputs and Gemini often returned similar three-noun-plus-digits structures, reducing effective entropy. The article advises using passkeys, two-factor authentication, or manual/randomized methods instead of relying on LLM-generated passwords.
