LLM-generated passwords (generated directly by the LLM, rather than by an agent using a tool) appear strong, but are fundamentally insecure, because LLMs are designed to predict tokens – the opposite of securely and uniformly sampling random characters.

Even where they aren't, I bet this is something that could end up happening when using them as open-ended agents that might try making their own accounts. The article also mentions this:

Furthermore, with the recent surge in popularity of coding agents and vibe-coding tools, people are increasingly developing software without looking at the code. We’ve seen that these coding agents are prone to using LLM-generated passwords without the developer’s knowledge or choice. When users don’t review the agent actions or the resulting source code, this “vibe-password-generation” is easy to miss.
