Keychain Access is a Mac OS X application that allows the user to access the Keychain and configure its contents, including passwords for websites, web forms, FTP servers, SSH accounts, network shares, wireless networks, encrypted disk images, etc. A keychain can store all your passwords for applications, servers, and websites, or even sensitive information unrelated to your computer, such as credit card numbers or personal identification numbers (PINs) for bank accounts. Only the passwords and Secure Notes are encrypted. The keychain file stores a variety of information including a title, URL, notes and password. However, if you want to prevent unauthorized people from using your MacBook and accessing pages with your personal information, you can disable the AutoFill feature.
For example, AutoFill can take care of your user name, password an credit card information when you log in to a site or enter your contact information into a form. If you are using your MacBook for business purposes, you can save time by enabling the Safari Web browser’s AutoFill feature to automatically enter your personal information into Web page forms for you.
