Problem 53720. Secure Password

I don't think any human could remember all the passwords my function just generated!

I would recommend breaking up the assertions into individual calls to help the user diagnose specific problems when/if their function does not pass. I have provided a commented-out example of such a set with my solution.

This is a good problem. Thanks.

That's an excellent suggestion Grant!
I have implemented the individual assertion calls you provided.
And I'm glad you like the problem!
