Enabling password protection on Macintosh computers involves the
following two steps:
- Configuring password protection
- Disabling auto-logon
Detailed instructions for these two steps are provided below.
Configuring Password Protection
on Macintosh OS X
1. Click on the Apple icon located on the top
left corner of your Mac screen. This will present you with a
menu as shown in Figure 1.

option. You will be presented with a list of all of the
local login accounts that exist on your system (see Figure 3 for
an example).

the "Login Options” button. NOTE: To access these
login options you may need to click on the lock located at the

password.

5. Click on the
name of the account that you would like to use to login.
6. To change the
password associated with the account, click on the "Change
Password" button and type a new password.
Disabling Auto-Logon on Macintosh
OS X
1. Follow steps 1, 2 and 3 listed above under
"Configuring Password Protection".
2. The “Login Options” screen provides the
options to turn off the Automatic Logon setting. If the “Automatic
log in as” is checked, you should uncheck this option.
3. Select "Name and password" for the
“Display login window as:” option. This will limit
the ability for someone to know what ID to target in order to
get into the system.
