Passwordless
Overview
This page contains the APIs that are used to authenticate users without passwords using magic links and codes.
You also may find the Magic Links guide helpful.
Prior to version 1.41.0
, magic links and codes were the only form of passwordless authentication supported by FusionAuth.
Therefore the user interface and API use the term passwordless
, even though versions 1.41.0
and beyond support multiple kinds of passwordless authentication.
Start Passwordless Login
This API has been available since 1.11.0
This API allows you to generate a passwordless code that can be used to complete login. This is the first step in completing a passwordless login.
If you plan to utilize the FusionAuth login page then you will not need to use this API. Instead, once passwordless authentication is enabled for the FusionAuth Application, a new button will be presented to the user on the login page which will allow them to request an email.
Request
Request Headers
X-FusionAuth-TenantId
StringThe unique Id of the tenant used to scope this API request.
The tenant Id is not required on this request even when more than one tenant has been configured because the tenant can be identified based upon the request parameters or it is otherwise not required.
Specify a tenant Id on this request when you want to ensure the request is scoped to a specific tenant. The tenant Id may be provided through this header or by using a tenant locked API key to achieve the same result.
See Making an API request using a Tenant Id for additional information.
Request Body
applicationId
StringrequiredThe unique Id of the Application you are requesting to log into.
loginId
StringrequiredThe login identifier of the user. The login identifier can be either the email or the username .
state
ObjectAn optional object that will be returned un-modified when you complete the passwordless login request. This may be useful to return the user to particular state once they complete login using the passwordless code.

Send Passwordless Login
This API allows you to send an email to a user that will contain a code that can be used to complete login. This API should be used if you want to build your own login page.
If you plan to utilize the FusionAuth login page then you will not need to use this API. Instead, once passwordless authentication is enabled for the FusionAuth Application, a new button will be presented to the user on the login page which will allow them to request an email.
This API does not require authentication.

which means you will need to use the Start API prior to calling this API.

Complete a Passwordless Login
This API is used to complete the passwordless login request. This API should be used if you want to build your own login page.
If you plan to utilize the FusionAuth login page then you will not need to use this API. Instead, once passwordless authentication is enabled for the FusionAuth Application, a new button will be presented to the user on the login page which will allow them to request an email.
This API does not require authentication.
Request
Request Headers
X-Forwarded-For
StringThe IP address of a client requesting authentication. If the IP address is provided it will be stored for login history of the user. It is generally preferred to specify the IP address in the request body. If it is not provided in the request body this header value will be used if available, the request body value will take precedence.
X-FusionAuth-TenantId
StringThe unique Id of the tenant used to scope this API request.
The tenant Id is not required on this request even when more than one tenant has been configured because the tenant can be identified based upon the request parameters or it is otherwise not required.
Specify a tenant Id on this request when you want to ensure the request is scoped to a specific tenant. The tenant Id may be provided through this header or by using a tenant locked API key to achieve the same result.
See Making an API request using a Tenant Id for additional information.
Request Cookies
fusionauth.trust
StringThe Two Factor Trust identifier returned by the Two Factor Login API response. This value may be provided to bypass the Two Factor challenge when a User has Two Factor enabled. When this cookie exists on the request it will take precedence over the twoFactorTrustId if provided in the request body.
Request Parameters
applicationId
StringThe unique Id of the Application you are requesting to log into. If omitted, no application-specific settings such as lambdas or email templates will be applied.
code
StringrequiredThe unique code sent via email used to complete the login request.
ipAddress
StringThe IP address of the end-user that is logging into FusionAuth. If this value is omitted FusionAuth will attempt to obtain the IP address of
the client, the value will be that of the X-Forwarded-For
header if provided or the last proxy that sent the request. The IP address will
be stored in the User login history.
metaData.device.description
StringA human readable description of the device used during login. This meta data is used to describe the refresh token that may be generated for this login request.
metaData.device.name
StringA human readable name of the device used during login. This meta data is used to describe the refresh token that may be generated for this login request.
metaData.device.type
StringThe type of device represented by the device
parameter. This meta data is used to describe the refresh token that may be generated for this login request.
Prior to version 1.46.0, this value was restricted to the following types:
BROWSER
DESKTOP
LAPTOP
MOBILE
OTHER
SERVER
TABLET
TV
UNKNOWN
In version 1.46.0
and beyond, this value can be any string value you’d like, have fun with it!
noJWT
BooleanDefaults to falseWhen this value is set to true a JWT will not be issued as part of this request. The response body will not contain the token
or refreshToken
fields, and the access_token
and refresh_token
cookies will not be written to the HTTP response.
This optional parameter may be helpful when performing high volume authentication requests and the JWT is not being utilized, in this scenario removing the additional latency required to issue and sign the JWT may have a measurable cumulative effect on performance.
twoFactorTrustId
StringThe Two Factor Trust identifier returned by the Two Factor Login API response. This value may be provided to bypass the Two Factor challenge when a User has Two Factor enabled.
