If you don't have an account, just leave the password field blank.
As an addition to that: Put in simple terms, beta testing a D-Mod would generally involve sending your D-Mod out to just a few people (two or three perhaps, maybe more for a large one) so they can spot bugs and make suggestions for improvements. After beta testing is finished and all obvious issues are resolved, the D-Mod is released and everyone celebrates.
