Sounds like you're talking about the bootloader password.

The most practical way to bypass that password is to boot from a 
different medium (like a rescue disk).

For the login password (the one that usually comes from 
/etc/passwd or /etc/shadow), the easiest way to bypass that is 
to boot with the kernel argument "init=/bin/sh", which causes 
the kernel to start the system shell instead of /sbin/init.  
Then you can muck around with the system using the standard 
system shell (usually bash).  Of course, if there's a bootloader 
password, you probably can't actually use this trick unless 
you've bypassed the bootloader password.
