Default PW for PHPmyadmin?

Hello all, this is probably a dumb question but…

I just installed the PHPBB stack and it works quite well. I can access the forum no problem but can’t configure the forum using PHPmyadmin:

“You can access the built-in management tool phpMyAdmin here. For security reasons it is password protected and only accessible when using 127.0.0.1 as the hostname.”

Is this the SQL password or… ? If not, what is the default password during installation?

Thanks in advance.
