Create Login Flow for Browsers

This endpoint initializes a browser-based user login flow. This endpoint will set the appropriate cookies and anti-CSRF measures required for browser-based flows.

If this endpoint is opened as a link in the browser, it will be redirected to selfservice.flows.login.ui_url with the flow ID set as the query parameter ?flow=. If a valid user session exists already, the browser will be redirected to urls.default_redirect_url unless the query parameter ?refresh=true was set.

If this endpoint is called via an AJAX request, the response contains the flow without a redirect. In the case of an error, the error.id of the JSON response body can be one of:

session_already_available: The user is already signed in. session_aal1_required: Multi-factor auth (e.g. 2fa) was requested but the user has no session yet. security_csrf_violation: Unable to fetch the flow because a CSRF violation occurred. security_identity_mismatch: The requested ?return_to address is not allowed to be used. Adjust this in the configuration!

The optional query parameter login_challenge is set when using Kratos with Hydra in an OAuth2 flow. See the oauth2_provider.url configuration option.

This endpoint is NOT INTENDED for clients that do not have a browser (Chrome, Firefox, ...) as cookies are needed.

More information can be found at Ory Kratos User Login and User Registration Documentation.

Query parameters

refreshboolean

Refresh a login session

If set to true, this will refresh an existing login session by asking the user to sign in again. This will reset the authenticated_at time of the session.

aalstring

Request a Specific AuthenticationMethod Assurance Level

Use this parameter to upgrade an existing session's authenticator assurance level (AAL). This allows you to ask for multi-factor authentication. When an identity sign in using e.g. username+password, the AAL is 1. If you wish to "upgrade" the session's security by asking the user to perform TOTP / WebAuth/ ... you would set this to "aal2".

return_tostring

The URL to return the browser to after the flow was completed.

login_challengestring

An optional Hydra login challenge. If present, Kratos will cooperate with Ory Hydra to act as an OAuth2 identity provider.

The value for this parameter comes from login_challenge URL Query parameter sent to your application (e.g. /login?login_challenge=abcde).

organizationstring

An optional organization ID that should be used for logging this user in. This parameter is only effective in the Ory Network.

viastring

Via should contain the identity's credential the code should be sent to. Only relevant in aal2 flows.

DEPRECATED: This field is deprecated. Please remove it from your requests. The user will now see a choice of MFA credentials to choose from to perform the second factor instead.

identity_schemastring

An optional identity schema to use for the login flow.

Headers

Cookiestring

HTTP Cookies

When using the SDK in a browser app, on the server side you must include the HTTP Cookie Header sent by the client to your server here. This ensures that CSRF and session cookies are respected.

It is not used within the credentials object itself. code_recovery CredentialsTypeRecoveryCode

created_atstring date-time

CreatedAt is a helper struct field for gobuffalo.pop.

expires_atstring date-time required

ExpiresAt is the time (UTC) when the flow expires. If the user still wishes to log in, a new flow has to be initiated.

idstring uuid required

ID represents the flow's unique ID. When performing the login flow, this represents the id in the login UI's query parameter: http://<selfservice.flows.login.ui_url>/?flow=<flow_id>

identity_schemastring

IdentitySchema optionally holds the ID of the identity schema that is used for this flow. This value can be set by the user when creating the flow and should be retained when the flow is saved or converted to another flow.

issued_atstring date-time required

IssuedAt is the time (UTC) when the flow started.

oauth2_login_challengestring

Ory OAuth 2.0 Login Challenge.

This value is set using the login_challenge query parameter of the registration and login endpoints. If set will cooperate with Ory OAuth2 and OpenID to act as an OAuth2 server / OpenID Provider.

refreshboolean

Refresh stores whether this login flow should enforce re-authentication.

request_urlstring required

RequestURL is the initial URL that was requested from Ory Kratos. It can be used to forward information contained in the URL's path or query for example.

requested_aalstring

The authenticator assurance level can be one of "aal1", "aal2", or "aal3". A higher number means that it is harder for an attacker to compromise the account.

Generally, "aal1" implies that one authentication factor was used while AAL2 implies that two factors (e.g. password + TOTP) have been used.

return_tostring

ReturnTo contains the requested return_to URL.

session_token_exchange_codestring

SessionTokenExchangeCode holds the secret code that the client can use to retrieve a session token after the login flow has been completed. This is only set if the client has requested a session token exchange code, and if the flow is of type "api", and only on creating the login flow.

transient_payloadobject

TransientPayload is used to pass data from the login to hooks and email templates

typestring required

The flow type can either be api or browser.

updated_atstring date-time

UpdatedAt is a helper struct field for gobuffalo.pop.
