Password complexity requirements are still a load of crap. No one knows where the crap came from. Searching for the history of complexity requirements seems to point to Microsoft NT 3.5. And we know complex passwords result in weaker passwords from Security Usability studies. Another load of crap is password rotation policies. You never throw away a good secret unless there's evidence of misuse or breach. And forcing users to gratuitously change their password results in users choosing weaker and weaker passwords over time as they are constantly grinded on to change good passwords. We know this from Security Usability studies. Anyone designing an authentication system would be well served to read Peter Gutmann's Engineering Security, <https://www.cs.auckland.ac.nz/~pgut001/pubs/book.pdf>. Chapter 7 covers Passwords.
