OpenID security issue

I am very pleased that OpenID is finally taking off, I have too many site logons as it is. However, it does raise a security implication, because once my personal data has been concatenated to the point that it's as dangerous as a leak of enriched uranium waste.. someone gaining access to my bank logins subject me to fraud ultimately. I personally am pleased my online banking all has a different login system for security. if banks did ever unify their login systems I'd hold out to have a separate account for each system, as I would never use my bank login from a web-cafe as I can't be sure if it's secure.
