+description: "Learn how to authenticate with Infisical using TLS Certificate."
+---
+
+**TLS Certificate Auth** is an authentication method that verifies a user's TLS Client certificate using the provided CA Certificate, allowing secure access to Infisical resources.
+
+## Diagram
+
+The following sequence diagram illustrates the TLS Certificate Auth workflow for authenticating users with Infisical.
+
+```mermaid
+sequenceDiagram
+  participant Client
+  participant Infisical
+
+  Note over Client,Client: Step 1: Setup your TLS request with the client certificate
+
+  Note over Client,Infisical: Step 2: Login Operation
+  Client->>Infisical: Send request to /api/v1/auth/tls-cert-auth/login
+
+  Note over Infisical: Step 3: Request verification using CA Certificate
+
+  Infisical->>Client: Return short-lived access token
+
+  Note over Client,Infisical: Step 5: Access Infisical API with token
+  Client->>Infisical: Make authenticated requests using the short-lived access token
+```
+
+## Concept
+
+At a high level, Infisical authenticates the client's TLS Certificate by verifying its identity and checking that it meets specific requirements (e.g., it is bound to the allowed common names) at the `/api/v1/auth/tls-cert-auth/login` endpoint. If successful, Infisical returns a short-lived access token that can be used to make authenticated requests to the Infisical API.
+
+To be more specific:
+
+1. The client sends a TLS request with the client certificate to Infisical at the `/api/v1/auth/tls-cert-auth/login` endpoint.
+2. Infisical verifies the incoming request using the provided CA certificate.
+3. Infisical checks the user's properties against set criteria such as Allowed Common Names.
+4. If all checks pass, Infisical returns a short-lived access token that the client can use to make authenticated requests to the Infisical API.
+
+<Accordion title="TLS with Load Balancer/Proxy">
+  Most of the time, the Infisical server will be behind a load balancer or
+  proxy. To propagate the TLS certificate from the load balancer to the
+  instance, you can configure the TLS to send the client certificate as a header
+  that is set as an [environment
+  variable](/self-hosting/configuration/envars#param-identity-tls-cert-auth-client-certificate-header-key).
+</Accordion>
+
+## Guide
+
+In the following steps, we explore how to create and use identities for your workloads and applications on TLS Certificate to
+access the Infisical API using request signing.
+
+<Warning>
+  **Self-Hosted Users:** Before using TLS Certificate Auth, please review the
+  [Security Requirements for Self-Hosted
+  Deployments](#security-requirements-for-self-hosted-deployments) section below
+  to ensure proper configuration and avoid security vulnerabilities.
+</Warning>
+
+### Creating an identity
+
+To create an identity, head to your Organization Settings > Access Control > [Identities](https://app.infisical.com/organization/access-management?selectedTab=identities) and press **Create identity**.
+
+![identities organization](/images/platform/identities/identities-org.png)
+
+When creating an identity, you specify an organization-level [role](/documentation/platform/role-based-access-controls) for it to assume; you can configure roles in Organization Settings > Access Control > [Organization Roles](https://app.infisical.com/organization/access-management?selectedTab=roles).
+
+![identities organization create](/images/platform/identities/identities-org-create.png)
+
+Input some details for your new identity:
+
+- **Name (required):** A friendly name for the identity.
+- **Role (required):** A role from the [**Organization Roles**](https://app.infisical.com/organization/access-management?selectedTab=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.
+
+![identities page](/images/platform/identities/identities-page.png)
+
+Since the identity has been configured with [Universal Auth](https://infisical.com/docs/documentation/platform/identities/universal-auth) by default, you should reconfigure it to use TLS Certificate Auth instead. To do this, click the cog next to **Universal Auth** and then select **Delete** in the options dropdown.
+
+![identities press cog](/images/platform/identities/identities-press-cog.png)
+
+![identities page remove default auth](/images/platform/identities/identities-page-remove-default-auth.png)
+
+Now create a new TLS Certificate Auth Method.
+
+![identities create tls cert auth method](/images/platform/identities/identities-tls-cert-auth-create-auth.png)
+
+Here's some information about each field:
+
+- **CA Certificate:** A PEM encoded CA Certificate used to validate incoming TLS request client certificate.
+- **Allowed Common Names:** A comma separated list of client certificate common names allowed.
+- **Access Token TTL (default is `2592000` equivalent to 30 days):** The lifetime for an access 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 access 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 an 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.
+
+### Adding an identity to a project
+
+In order to allow an identity to access project-level resources such as secrets, you must add it to the relevant projects.
+
+To do this, head over to the project you want to add the identity to and navigate to Project Settings > Access Control > Machine Identities and press **Add Identity**.
+
+![identities project](/images/platform/identities/identities-project.png)
+
+Select the identity you want to add to the project and the project-level role you want it to assume. The project role given to the identity will determine what project-level resources this identity can access.
+
+![identities project create](/images/platform/identities/identities-project-create.png)
+
+### Accessing the Infisical API with the identity
+
+To access the Infisical API as the identity, you need to send a TLS request to `/api/v1/auth/tls-cert-auth/login` endpoint.
+
+Below is an example of how you can authenticate with Infisical using NodeJS.
+
+```javascript
+const fs = require("fs");
+const https = require("https");
+const axios = require("axios");
+
+try {
+  const clientCertificate = fs.readFileSync("client-cert.pem", "utf8");
+  const clientKeyCertificate = fs.readFileSync("client-key.pem", "utf8");
+
+  const infisicalUrl = "https://app.infisical.com"; // or your self-hosted Infisical URL
+  const identityId = "<your-identity-id>";
+
+  // Create HTTPS agent with client certificate and key
+  const httpsAgent = new https.Agent({
+    cert: clientCertificate,
+    key: clientKeyCertificate,

+
+<Note>
+    Each identity access token has a time-to-live (TTL) which you can infer from the response of the login operation; the default TTL is `7200` seconds, which can be adjusted.
+
+    If an identity access token expires, it can no longer access the Infisical API. A new access token should be obtained by performing another login operation.

+## Security Requirements for Self-Hosted Deployments
+
+ALL TLS cert [login](/api-reference/endpoints/tls-cert-auth/login) requests **MUST** go through a load balancer/proxy that verifies certificate ownership:
+
+- **REQUIRED:** Configure your load balancer/proxy to **require a proper TLS handshake with client certificate presentation**
+- **REQUIRED:** Ensure the load balancer **verifies the client possesses the private key** corresponding to the certificate (standard TLS behavior)
+- **NEVER** allow direct connections to Infisical for TLS cert auth - this enables header injection attacks
+- **NEVER** forward certificate headers without requiring proper TLS certificate presentation
+
+### Load Balancer Configuration Examples
+
+- **AWS ALB:** Use mTLS listeners which require client certificate presentation during the TLS handshake
+- **NGINX/HAProxy:** Configure SSL client certificate requirement with proper TLS handshake verification
+
+<Note>
+  Infisical will handle the actual certificate validation against the configured
+  CA certificate and determine authentication permissions. The load balancer's
+  role is to ensure certificate ownership, not certificate trust validation.
+</Note>
