Question regarding heightened security of CMSB 2.52-3+ and Facebook Signup/Signin Plugin

As we are aware the more updated versions of CMSBuilder check passwords against a 10,000+ common password list and denies the use of passwords on that list (no complaints there!). My question is, if I purchase and integrate the Facebook Signup/Signin plugin (it was built originally for earlier versions of CMSB) will there be a conflict between the FB plugin and the heightened password security parameters - such as the user's FB password is on the anti-don't-letthem-use-it list?

Thank you in advance - especially if it's an expeditious response! ;-)
