I am currently looking for a password generator which produces pronounceable passwords. I have used this random password generator a few years ago to generate a 42 characters long password and found it remarkably well to remember. Even after all this time (and I don't have to type that password that often), I can remember and type it without making any mistakes and without having to think about it too much. It is a completely nonsensical sequence of letters, but it basically follows the pattern of alternating between consonants and vowels, which I guess makes it so easy to remember (at least for me).
However, as I already suspected it back then and as is mentioned in this question, generating passwords online might be insecure. But I am not really sure what else to do, as I haven't found something similar which works locally.
So my question is, is there any tool that produces the same kind of passwords in a secure way?
