For many it removes the pain of having to re-authenticate every day with a one time code sent via email or text message. Chase was rolling out enforcement of this 2FA requirement for all customers in phases starting at the beginning of Oct so we got it flipped over to open banking in the nick of time! It’s also a more secure authentication mechanism because you’re not giving your username and password to a (trusted) 3rd party since it’s a direct connection to the bank. It should be more reliable too, less prone to outages and connection errors.
