Set Up TOTP Credentials & Generate 2FA Codes in n8n

This n8n workflow serves as a step-by-step guide to implementing Time-based One-Time Password (TOTP) generation directly within n8n, eliminating the need for mobile authenticator apps like Google Authenticator or Authy. Users start by extracting the otpauth:// link from a 2FA QR code provided by services such as OpenAI, Google, or GitHub using online tools. This link contains the essential secret key and issuer details required for TOTP setup.

Next, the guide walks through creating a dedicated TOTP credential in n8n: input the secret key into the Secret field and the service:username format (e.g., OpenAI:email@example.com) into the Label field, then save it. Finally, activate the workflow's Test mode to instantly generate the current 6-digit TOTP code along with seconds remaining, producing output identical to standard 2FA apps.

Benefits include seamless integration of 2FA into automated n8n workflows, enhanced security without app dependencies, and time savings for developers managing multiple accounts. It's particularly valuable for IT teams handling secure API accesses.

Use cases span security automation, such as dynamically generating codes for scheduled logins to AI services, GitHub CI/CD pipelines requiring 2FA, or HR onboarding processes for employee account setups. This simple yet powerful setup unlocks programmatic 2FA handling in any n8n automation.
