# Get Login Provider

`POST /public/login-provider`

Public endpoint — resolves which login flow serves an email address, by
the login_provider_type of the company owning the email's domain, for the
email-first /auth page.

Keyed on domain, not the user (two emails at the same domain return the
same answer), so it discloses a domain's login provider like any
email-first SSO flow, and never whether a particular user exists.
