Azure Auth

To create an identity, head to your Organization Settings > Access Control > Machine Identities and press Create identity.

When creating an identity, you specify an organization level role for it to assume; you can configure roles in Organization Settings > Access Control > Organization Roles.

Now input a few details for your new identity. Here’s some guidance for each field:

• Name (required): A friendly name for the identity.
• Role (required): A role from the Organization Roles tab for the identity to assume. The organization role assigned will determine what organization level resources this identity can have access to.

Once you’ve created an identity, you’ll be redirected to a page where you can manage the identity.

Since the identity has been configured with Universal Auth by default, you should re-configure it to use Azure Auth instead. To do this, press to edit the Authentication section, remove the existing Universal Auth configuration, and add a new Azure Auth configuration onto the identity.

Here’s some more guidance on each field:

• Tenant ID: The tenant ID for the Azure AD organization.
• Resource / Audience: The resource URL for the application registered in Azure AD. The value is expected to match the aud claim of the access token JWT later used in the login operation against Infisical. See the resource parameter for how the audience is set when requesting a JWT access token from the Azure Instance Metadata Service (IMDS) endpoint. In most cases, this value should be https://management.azure.com/ which is the default.
• Allowed Service Principal IDs: A comma-separated list of Azure AD service principal IDs that are allowed to authenticate with Infisical.
• Access Token TTL (default is 2592000 equivalent to 30 days): The lifetime for an acccess token in seconds. This value will be referenced at renewal time.
• Access Token Max TTL (default is 2592000 equivalent to 30 days): The maximum lifetime for an acccess token in seconds. This value will be referenced at renewal time.
• Access Token Max Number of Uses (default is 0): The maximum number of times that an access token can be used; a value of 0 implies infinite number of uses.
• Access Token Trusted IPs: The IPs or CIDR ranges that access tokens can be used from. By default, each token is given the 0.0.0.0/0, allowing usage from any network address.

To enable the identity to access project-level resources such as secrets within a specific project, you should add it to that project.

To do this, head over to the project you want to add the identity to and go to Project Settings > Access Control > Machine Identities and press Add identity.

Next, select the identity you want to add to the project and the project level role you want to allow it to assume. The project role assigned will determine what project level resources this identity can have access to.

To access the Infisical API as the identity, you need to generate a managed identity access token that is a JWT token representing the managed identity for the Azure resource such as a Virtual Machine. The client token must be sent to the /api/v1/auth/azure-auth/login endpoint in exchange for a separate access token to access the Infisical API.

We provide a few code examples below of how you can authenticate with Infisical to access the Infisical API.

curl 'http://169.254.169.254/metadata/identity/oauth2/token?api-version=2018-02-01&resource=https%3A%2F%2Fmanagement.azure.com%2F' -H Metadata:true -s
