Vibe Password Generation: Predictable by Design - Irregular
LLM-generated passwords appear strong, but are fundamentally insecure. Testing across GPT, Claude, and Gemini revealed highly predictable patterns: repeated passwords across runs, skewed character distributions, and dramatically lower entropy than expected. Coding agents compound the problem by sometimes preferring and using LLM-generated passwords without the user’s knowledge. We recommend avoiding LLM-generated passwords and directing both models and coding agents to use secure password generation methods instead.
