"Safari wants to use your confidential information stored in "website" in your keychain" I had to install Google Chrome on my Mac for some reason, but do not intend to use it as my default browser. After logging in with my Google account, the following happened:


All my saved passwords on Chrome now appear in Safari saved passwords. I have no idea how this has been done.
Each time I visit a website in Safari, there's a popup saying "Safari wants to use your confidential information stored in "website" in your keychain". 


For the 1st problem, ok it's fine, although it should have asked for my approval before importing the passwords. The 2nd is really annoying. Please suggest me a way to get rid of those popups (without disabling Keychain of course).

Thank you in advance for your help.
Open Keychain Access.app in your Utilities folder. Highlight one of
  familiar keychain entries on the right side or type a familiar name in
  the spotlight panel. 
  
  Then double click the entry. When the panel opens, select "Access
  Control".
  
  In the "Always allow access" panel, click on the +, then navigate to
  Safari in your Applications folder. Save changes.
  
  Just for good measure, go to the Keychains Menu>Keychain First-Aid and
  select "repair". If any errors appear, rerun until you get a clean
  pass.
  
  Close Keychain Access and restart Safari.
