You should not give your bookkeeper YOUR login information for anything if you can help it. This puts your money at risk.

Most financial software, even banks and credit card accounts, can add your bookkeeper as their own user and restrict their access to the tasks they’ve been assigned (like invoicing or bill payments) or have them as a read only user that can only access statements.

The best part is the ability to simply remove them as a user, removing their access to your finances, and does not require you to change your passwords.
