0000
The default 4 digit password installed onto the PSP is 0000 (four zeros).
If you're PSP can run homebrew, download the password retriever in related links. Otherwise there seems to be almost no ways to retrieve the password.
There is no way sorry
You don't
fdd
You have to guess the password that's what i did to my used wii.
You go to security settings, enter the current password and then go to change password
Did you had input correct password?
actually, i had a psp and the password to get thrue was 0000. my psp broke and i got a new one. the password was still 0000. try 0000
if it says its timed out you have the wrong password. you can figure out the password or remove using your computer
it is a type of a code or password to get on the internet
