8.8 B1 Site User Password

Hi All,

I am installing 8.8 and I have not been given a prompt for the B1SiteUser, this been the case I not finish the install. 

If I open up the Server Manager and go to the u2018license Manageru2019 I can see that I can re set this, however I do not know what the original / standard password is.

Can any one help me.

Thank you
