Whether you want to watch a "not-recommended for younger audiences" movie and just can't remember your own password, or you've bought a used PS2 that the owner didn't supply the password for - there will probably come a time when you'll have to reset the password on your PS2. Fortunately - this is very easy to do, and can be done in a matter of seconds.
Step 1: Step 1
1. Turn the PS2 on.
2. Insert your DVD/Game.
3. When prompted to input your password, select '7444'.
4. The password will have been deleted, and you'll need to set up a new one.
