Account expired in Archiva

I am using archiva in stand alone mode and my admin account has expired.  Develper accoints have expired also and can not browse the repository using the UI.

Can I implement the security.properties file in my maven directory without and damage to the archiva database or is it too late now.  What can I do to get my admin account and others back?

Thanks,
