Optum says this is a policy change to require MFA directly on their website and will no longer allow aggregators access to our data, so this won’t be temporary.
For many of us, I think the workaround is to download a CSV from Optum and import it to Tiller. Tiller doesn’t currently have an Optum selection for column mapping in the Community Solutions Extension. I’ll enter a Feature request for that. Randy has a workflow for a Basic Bank Importer. Here’s a Tiller resource article on importing a CSV if you choose that route. There’s no way to export/import account balances that I am aware of, so I’ll switch Optum to a manual account and update balances monthly. (what a pain, Optum!)
