How would you differeniate between a user login and another account on a website?

I am working on a project with a financial company. They require a user to create a financial account and then create an online account. Currently, they are both referenced as "Account". The issue I have is that it seems confusing to me to have two account types on the site.

So one of these would have to be changed to something else to make better sense.

Users can have more than one "financial account" tied to their "online account" so I am thinking the online account name should be considered "My account" since I believe most users would think in that pattern.

I would change the Account meant for financial accounts to something else but I am not sure what makes sense.

Please let me know if you have any thoughts that could help.
