Mint is another example of a popular financial management tool, that was always cloud-first. It would import transactions by using the same credentials you would use to login to online banking. This wasn't appealing to me. This didn't deter many other people.
I didn't like sharing my credentials either but I was using it – until it stopped working for most of my accounts.
I've since stopped using even the 'manual import' and I've found that reconciling to my bank/financial-company statements manually is much easier overall as importing auto-reconciled transactions but then it was basically impossible to then match any specific balance reported by the bank/financial-company.
