Organisations within Flagsmith can be locked to a single authentication method if required, meaning that accounts can neither be created or logged into with anything other than the method specified.

This can be configured at an Organisation level by a Super-Administrator. Please get in touch if you need help with this.

As well as Email/Password and OAuth2 via Google or Github, we also provide the following methods of authentication.


The Flagsmith platform can be configured for a given organisation to use SAML authentication. To configure SAML login for your organisation please get in touch with us directly to help set it up.

The steps we need to go through are something like:

  1. You contact us to enable SAML for your organisation.
  2. We create an XML file and provide it to you along with your SAML organisation name.
  3. You supply the XML to your SAML IDP and receive some XML in return. You might need to apply some attribute mappings.
  4. You send us this XML and we add it to Flagsmith.
  5. You log in by visiting clicking on "Single Sign On" and entering your SAML organisation name from step 2.

Note that users authenticated via SAML can only belong to one organisation, the one that the SAML configuration is tied to.

To set up SAML authentication, we will provide you with a unique name for your SAML organisation that you must then enter when prompted by the 'Single Sign on' dialog. We will also provide you with our Service Provider metadata and expect your IdP metadata in return.

SAML - On-premise

To allow an Organisation on the Flagsmith platform to login using SAML authentication, you'll need to access the admin interface. Instructions on how to access the admin interface can be found here.

Once you've logged into the django admin interface, you'll need to click on the 'Saml Configurations' option in the menu on the left. From here, you should see a list of existing SAML configuration entities. To create a new one, click on the 'ADD SAML CONFIGURATION' button in the top right corner of the screen.

You should see a screen similar to the following.

SAML Auth Setup

From the drop down next to Organisation, select the organisation in the Flagsmith platform that you want to configure for SAML authentication.

Next to Organisation name, add a name without any spaces that identifies the organisation uniquely for the installation of Flagsmith you're working on. This is what users will provide when authenticating with SAML so that the platform knows where to redirect them.

Next to Frontend url, add in the URL at which your Frontend application is running. This is where users will be redirected to on a successful SAML authentication.

For now, we'll leave Idp metadata xml empty.

Once you've completed these fields, hit the Save button to create the SAML configuration.

Now, we need to grab the Flagsmith service provider metadata to configure the integration on your IDP. To do this, open a new browser tab and head to https://<your Flagsmith API>/api/v1/auth/saml/<organisation_name>/metadata/ where <organisation_name> is the name you provided above. From here, copy and paste what you see in the web page into a new text file and save that file as flagsmith-sp-metadata.xml or similar.

Note: do not use 'save page as' from your browser as this will likely result in the metadata being incorrect and the integration will not work.

Now you can use this XML metadata to create the integration on your IDP. Once created on the IDP, you can add the IDP metadata into the Idp metadata xml field that we left blank earlier.

Attribute Mapping information

To uniquely identify users, we attempt to retrieve a unique identifier from either the subject-id or uid claim, or we use the content of the NameID attribute.

We also map the following Flagsmith user attributes to the following claims in the SAML response.

Flagsmith AttributeIdP claims
emailmail, email or emailAddress
first_namegn, givenName or (the first part of) displayName
last_namesn, surname or (the second part of) displayName

Here's an example configuration from Google's SAML app creation flow.
