Who is this workflow for? This guide provides a comprehensive walkthrough for setting up and generating Time-based One-Time Password (TOTP) codes using n8n. By following these steps, you can enhance the security of your workflows with two-factor authentication (2FA)..

What does this workflow do?

  • Receive the QR Code from the 2FA ServiceAfter enabling two-factor authentication (2FA) on services such as OpenAI, Google, GitHub, etc., you will receive a QR Code. This QR Code encodes the TOTP link necessary for generating one-time passcodes.

  • Extract the Link from the QR CodeUse an online QR Code decoder tool to extract the TOTP link from the received QR Code. The extracted link typically follows this format:

   otpauth://totp/ServiceName:username?secret=secret_key&issuer=ServiceName

Example:

   otpauth://totp/OpenAI:[email protected]?secret=test-test-test&issuer=OpenAI

Step 2: Create TOTP Credential in n8n

  • Create a New CredentialIn n8n, navigate to the Credentials section and create a new TOTP Credential.

  • Enter the Credential Details

  • Secret: Input the secret key extracted from the QR Code link (e.g., test-test-test).

  • Label: Enter a descriptive label in the format ServiceName:username (e.g., OpenAI:[email protected]).

    Credential Setup

  • Save the CredentialAfter entering the necessary information, click Save to store the credential securely in n8n.

Step 3: Generate the TOTP Code

  • Test the WorkflowWith the TOTP credential configured, execute a test workflow in n8n by clicking on Test Workflow. This action will generate a TOTP code.

  • Retrieve the TOTP CodeThe output will display the generated TOTP code along with the remaining validity period:

   [     {       "token": "720769",       "secondsRemaining": 18     }   ]

TOTP Code

Note: The generated code is identical to those produced by authenticator apps like Google Authenticator or Authy.

This workflow integrates seamlessly with various platforms and services, including:

  • Facebook
  • Instagram
  • HTTP Request
  • Merge
  • Google Sheets
  • Microsoft Excel
  • Gmail
  • S3
  • Respond to Webhook
  • Webhook
  • Telegram
