The first sign-in screen, where you say who you are, and the methods it can offer next to the form.
On this page
Every sign-in begins on one page, Sign in to TDACorp, with the line Use your TDACorp account. You reach it by opening the sign-in page directly, or because an application sent you there. The page is the same either way, and the address stays the same as the sign-in moves from step to step: each step replaces the one before it on the page.

- The email field, labelled Email on the current public sign-in page. Where the organization accepts a username as well, the field is labelled Email or username.
- Continue, which sends what you typed and moves to the next step.
- Sign in with a passkey, which skips typing and uses a passkey on your device.
