LLM-generated passwords ‘fundamentally weak,’ experts say • The Register

Posted by jpluimers on 2026/02/24

LLM eat a lot of energy and are their hallucination are bad: [Wayback/Archive] LLM-generated passwords ‘fundamentally weak,’ experts say • The Register

Your AI-generated password isn’t random, it just looks that way

AI security company Irregular looked at Claude, ChatGPT, and Gemini, and found all three GenAI tools put forward seemingly strong passwords that were, in fact, easily guessable.

Basically they are almost as good as the 2007 XKCD “four” number generator, the 2013 XKCD “I’m So Random” or the 2001 Dilbert “nine” number generator further below (don’t read the latter if you dislike Scott Adams)

Is it a coincidence or are these two using two small squared numbers?

Anyway: avoid LLM whenever possible, as most often they do more bad than good.

And for passwords, better use the blog post that was already scheduled for tomorrow: Generating random strings for passwords and uuids/guids on both Windows and Linux using base64 and hex encoding, plus: “Hive Systems: Are Your Passwords in the Green?”

Via [Wayback/Archive] Eloy.: “LLMs are centrist randomness: not useful for anything that requires truth but neither for password generation” – HSNL Social

Below this post, there are some great responses as well.

Chocolatey Software | GNU sed

Posted by jpluimers on 2026/02/24

I needed to document how to install sed on Windows (which I did a long time ago after writing Plastic SCM: show the current changeset abstract (without files) on the commandline) and recently for some more scripting work(which I will blog on that later this week).

At the time of writing it was [Wayback/Archive] Chocolatey Software | GNU sed 4.8, but this Chocolatey command will install or upgrade to the most recent available version:

choco upgrade --yes sed

Of course, like yesterday’s post Installing OpenSSL on Windows, you could use winget or scoop for this as well. Finding out the commands is left as an exercise to the reader (;

Query: [Wayback/Archive] chocolatey sed – Google Search
