Who is this workflow for? This n8n workflow template verifies the validity of a 6-digit Time-Based One-Time Password (TOTP) using a provided TOTP secret. It seamlessly integrates into authentication systems to enhance security by ensuring that user-provided codes are accurate..

What does this workflow do?

  • Input Preparation:
  • TOTP Secret: Provide the base32-encoded TOTP secret associated with the user.
  • 6-Digit Code: Input the user-provided 6-digit TOTP code as a string to prevent issues with leading zeros.
  • Function Node Execution:
  • The Function node generates a TOTP code based on the provided secret.
  • It compares the generated code with the input code.
  • Validation Result:
  • Match Found: If the codes match, the workflow returns 1 and proceeds to the true branch.
  • No Match: If the codes do not match, the workflow returns 0 and follows the false branch.
  • Integration Points:
  • The workflow can be connected to databases (e.g., Google Sheets, Microsoft Excel) to retrieve user secrets.
  • It can trigger actions via HTTP requests or respond to webhooks based on validation outcomes.
  • Customization:
  • Modify lines 39 and 40 in the Function node with context-specific values to tailor the workflow to your environment.

🤖 Why Use This Automation Workflow?

  • Enhanced Security: Implements robust two-factor authentication by validating TOTP codes.
  • Automation: Streamlines the verification process without manual intervention.
  • Flexibility: Easily integrates with various platforms and services to fit diverse authentication needs.
