How to connect an account tied to my company's SSO?

I would like to add my 401K account via ADP (mykplan) but the only way I can access ADP is via my company’s SSO. Does this make it impossible to connect my account even though it does seem this site is supported by Tiller? Or is there a way to solve for this? Thanks!
