Keychain Access seems cluttered
I'm new to Apple, so Keychain Access (High Sierra 10.13.3 on MacBook Pro) seems very difficult to use. Keychains=Login & Category=Passwords, the screen fills with bogus lines. While the Kind column says it's an Application Password and the Kind column has Login; most lines do not have the password.
Is there some sort of Search parameter that will show only the real passwords? Or a specific Keychains/Category choice to ease the hunt?
