Q: OSX Yosemite Keychain Missing

Hi All,

I'm having some issue with OSX Keychain,

So far i had own my Macbook Air 11 2011, i have been enjoying the fact that i don really need to remember my password during working on Safari.

This few days i realise that my keychain on my Mac is missing, all is gone, my iCloud password , hotmail password, gmail password EVERYTHING~~ i need to key in back or reset password.

Anyone having the same issue or can explain what is happening ....

by the way it happened as well on my iMac as well ....
