Change account name used by app

When I open my 1Password app, it only asks for my password, not my account name. Apparently, it is using the wrong account name. How do I change that?

Hello @ctday! 👋

Are you adding your 1Password account to the app for the first time or have you already been using 1Password on your iPhone or iPad? What else do you see on the screen where you're being prompted to enter your account password? Are you able to unlock the app by entering your account password into 1Password?

I look forward to hearing from you.
