Generate TOTP 2FA Codes Directly in n8n Workflows
This workflow guides you through setting up TOTP credentials in n8n to generate one-time passcodes from QR codes, mimicking Google Authenticator without external apps.
This n8n workflow provides a complete setup for generating Time-based One-Time Passwords (TOTP) codes used in 2FA systems. It starts by extracting the secret key from a QR code provided by services like OpenAI, Google, or GitHub. Users then create a TOTP credential in n8n using the extracted secret and label, enabling instant code generation upon testing the workflow.
The benefits include eliminating the need for mobile authenticator apps, allowing seamless integration into automated n8n workflows for secure logins or API authentications. It outputs the current TOTP token and remaining seconds, matching exactly what apps like Authy produce, ensuring compatibility and reliability.
Use cases span security automation: trigger 2FA codes in scheduled tasks, chain with login nodes for unattended API access, or build multi-service authenticators. Ideal for developers automating secure workflows without phone dependency, enhancing productivity in DevOps, IT, and no-code environments.
