Hi geotony2gmail.com,

Welcome to Apple Support Communities.

It sounds like there is an issue with the login Keychain Access on your Mac, which is causing you to see an alert when you launch FaceTime. Take a look at the article below, it will resolve most Keychain issues.

Resetting your keychain in Mac OS X

I hope this helps.
