I just have a general question about security. First, I appreciate the common advice to not use the same password for multiple web sites. That is one reason I am using 1Password 4 on my Mac Book Pro. Yet, more and more websites seem to offer the alternative of using Facebook to login to their sites instead of creating a new login credentials for their website. This is tempting, but if I use my Facebook credentials for all of these sites isn't this the same as using the same password over and over again?
