Overview

The UTMStack Authentication API issues JWT tokens to clients who provide valid credentials. Clients must authenticate using this endpoint before calling any protected resource in the UTMStack platform.
This endpoint does not require authentication. It returns a JWT access token that must be used for subsequent requests.

Response Examples

​
Successful Authentication (TFA disabled)

  • Response
  • Headers
{
  "id_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJhZG1pbiIsImF1dGgiOiJST0xFX0FETUlOIiwiZXhwIjoxNjM0NTQ3MjAwfQ.signature",
  "authenticated": true
}

​
TFA Challenge (TFA enabled)

{
  "id_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJhZG1pbiIsInRmYSI6dHJ1ZSwiZXhwIjoxNjM0NTQ3MjAwfQ.signature",
  "authenticated": false
}
When authenticated is false, you need to complete the two-factor authentication process by providing the verification code sent to your email.

Error Handling

Description: Invalid credentials

Description: Login temporarily blocked due to multiple failed attempts
Resolution: Wait for cooldown period or contact admin.
Description: Unexpected backend error
Resolution: Check logs or contact UTMStack support.

​
Security Considerations

Important Security Notes:
  • Always use HTTPS (TLS) when sending credentials
  • Do not store plain-text passwords or tokens locally
  • Implement token expiration and refresh mechanisms in clients
  • If TFA is enabled, a second verification code is sent by email

​
Using the Token

After successful authentication, include the JWT token in the Authorization header for subsequent API requests: 
Authorization: Bearer <jwt_token>
Test your authentication by making a request to /api/elasticsearch/search with your Bearer token to verify it’s working correctly.
