I saw that there is a limited production mode, but it doesn't support institutions such as BofA or chase (https://plaid.com/docs/sandbox/#testing-with-live-data-using...). I submitted the questionnaire for production access and got access, but it says it will be revoked unless I complete a list of security attestation requirements.

Seems like the barrier to entry seems a bit high for personal use. Even with production access, I can't just link my bank accounts and use the API right as I would have to setup authentication and Link myself right? Looking forward to see more about the revamp, though.
