I recently connected my Chase checking to my work expense system via Plaid, and it appeared to use an real integration - I was sent to a Chase domain to log on, which explained what data I was giving to Plaid _as well as_ what data I was giving to the third (fourth?) party. I recall a similar experience linking Chase to my Schwab account. I was pleasantly surprised that I was not asked to give my bank password to anyone but my bank.
