Start OIDC step-up re-authentication
Begins a step-up re-authentication with a provider already linked to the authenticated account, and returns the provider authorize URL. On consent, the callback mints a short-lived, single-use proof required to add a credential (set a first password, or link a new provider).
Path Parameters
The identity provider to act on.
"password"Query Parameters
A step-up re-authentication proof. Required to start a link (adding a provider is a credential-adding action, so a live session alone is not enough); ignored for sign-in and reauth.
Frontend URL to return to once done. Carried through the flow and used to build the callback's redirect.
Response
The response to a successful sign-in start: where to send the user.
