You can do a lot worse that generate passwords using Diceware. This generator is a pretty rudimentary one. Default parameters are to produce five diceware words, but you can use other numbers and other params – try stuffing ?help on the end. The generator is here.
Note: When you use the above generator the diceware phrase is generated on my server, so you obviously should not use it for anything important. I also can’t vouch for the entropy source and there have been issues with the PHP RNG before. You have been warned!
You can also find a version here that runs at your end, but unless you can be botherd to read the source javascript, is it really any more secure? On the plus side, as it’s running at your end, it doesn’t have the same size limit! Knock yourself out!
If you do want to generate passwords online, here is a much more secure implementation than mine!
ChatGPT wrote both the PHP and the Javascript versions – pretty neat! If you are really nerdy, you can grab the wordlist as a JSON file.
