Enable password for single-user mode (OS X)

Single-user mode by default is available on OS X without a password. This is not a desirable system behavior and to remedy this, all that is needed are a few simple commands. To enable a higher level of security we can set an "Open Firmware Password".

On OS X 10.4.10, you need to use the updated version of the Open Firmware Password (v. 1.0.2) application from the software installation disc (located at /Applications/Utilities/ or at Apple-Support-Downloads). Then, just click the checkbox 'Require password to change Open Firmware settings,' set a password, and you're good to go.
