You can roll your own password system using the crypt module.
Get each user to create a password (or give them a default) and
encrypt it with crypt. Store the result and when they log in
compare the encrypted password with the stored one.

It may not have all the security features of the passlib
solution but its a lot better than nothing and will deter
most crackers long enough for them to get bored and move on.

The downside is that you need to build a password management
module/workflow/UI into your code to allow changes/resets etc.
