Hey @lja,
The pwd parameter was implemented for our Web Client specifically whereas the Web SDk is intended for building out your own Web Client where you could implement this feature if necessary. In other words, I don’t think there is a reason this hasn’t been included it just hasn’t been on our roadmap so far.
If you would like this feature to be considered for a future release, I recommend posting in the #feature-requests category.
Thanks,
Max
