Q&A

Q1: Are keychains really secure?
A1: The information stored for Keychain Access is encrypted, which makes it very difficult for someone to break into your computer and steal what’s stored there. However, as one newsgroup contributor cautions, “As with all mathematical encryption, cracking is only really a matter of how hard you try to solve the equation.” Also, if the passwords to access your keychains can be guessed, the rest of your passwords can be easily read.
Q2: You said I need my password to open my keychains, but I can’t remember it.
A2: Hour 24, “Maintenance and Troubleshooting,” tells you how to find out or reset your password.
Q3: I tried looking up people I know using the Finger feature of Network Utility, but I get the response “Connection refused.” Am I doing something wrong?
A3: No, that message doesn’t mean you’ve done something wrong. Many email systems do not support Finger as a function because they don’t want to give out personal information about their users.
