Currently, these providers are the three with the capability of connecting an existing account or creating an account within the Bud app. Using this service, you can create an account with any of the providers listed and aggregate your account within the app.
After connecting, your account(s) will then be listed on the home and accounts menus. We're excited to add more providers in the future should they be compatible for the app. For now, if you have an account with the providers in the app or you want to open one that you have checked suited to your needs, you can connect and see all your accounts from here!
