I was pleasantly surprised to see a few of the large banks having added OAuth in my recent use of a product that uses Plaid. That said, my local bank is far from it and even a large bank like Discover doesn't offer OAuth yet. I've just decided that I have to enter that data manually for those accounts because I can't give out a password to my bank accounts - it's just absurd to me.

Here's to a continued migration to OAuth by banks, but I'm not holding my breath for it.
