Autofill turned off but Tiller is still trying to login to my bank

I’ve turned off Autofill as my banks require MFA. However, at 12:15am almost every day something is trying to log in. I think it’s Tiller. When I update my password and don’t update it in Tiller the logins stop. Yesterday I updated my bank password in Tiller and the attempt happened again last night. Is Tiller trying to login even with Autofill turned off?

Fill and refresh are different processss. If the account is still in your console, Tiller will automatically try to refresh it (I believe they say that is, on average, every 36 hours). If Autofill is turned off, it just won’t try to fill your sheets with whatever data it gets from the refresh.
