Donors have the ability to create accounts to store information, view donation history, and modify or fix recurring donations. This is a built-in feature of GivingFire and can't be turned off, although using accounts is completely optional for the donor. Donor accounts can be accessed through the donation page, via a navigation bar at the top of the screen:

Once a user logs in, they'll see a customized dashboard for their account. This is different from the administrative dashboard - they'll only have access to their donations to your organization.
