how to turn off keychain pop ups

I had been trying to fix this issue for months on my mac. I just spoke to an apple rep and he helped me resolve this in less than a minute. Here is how:

1. In Finder, press the key 'option' and click on 'Library' under 'Go'.
2. In library folder, scroll down to 'keychain'.
3. Click on the arrow to the left of keychain to reveal what's under it.
4. Delete everything under keychain, but not the keychain folder itself. (In my case, I had to delete 3-4 files and a folder).
5. Restart the mac.
6. Voila, you are done. No more annoying pop-ups.
