# Sign in with email

Interactive sign-in lives on the HTML page.

Current browser flow submits `POST /session` with:

- `session[email]`
- `cf-turnstile-response` — Cloudflare Turnstile verification token from the HTML form

That request verifies Turnstile and then sends a one-time verification code by email. The backend decides whether this is a returning sign-in or the start of a new signup.

The HTML page also supports passkey sign-in when a passkey is registered for the account. Passkey sign-in is not challenged by Turnstile.
