Try the User Security Management Plugin by Adaptavist:

Among other features, it offers:

Better Password Control

1. A raft of password strength/complexity options
2. Password expiry (so you can make sure your users change their password every x days)
3. Password history lists (so you can make sure your user's don't change to a password they've used in the last x)
4. Password minimum change (so you can enforce a password change only once a day)
