Complete Guide to Setting Up and Generating OTP Codes in n8n

# Setting Up and Generating OTP ## Step 1: Receive QR Code and Extract the Link **1. Receive the QR Code from the 2FA service** After enabling two-factor authentication (2FA) on services like OpenAI, Google, GitHub, etc., a QR Code will be given to you, which you need to scan. This QR Code contains the OTP link used to generate one-time passcodes. **2. Extract the link from the received QR Code** To extract the link from the QR Code, use online tools. These tools will help you extract the corresponding link. After using an online tool, the extracted link will appear in the following format: ``` otpauth://totp/ServiceName:username?secret=secret_key&issuer=ServiceName ``` For example: ``` otpauth://totp/OpenAI:amir676080@gmail.com?secret=test-test-test&issuer=OpenAI ``` ## Step 2: Create OTP Credential in n8n 1. **Create a new Credential** To use OTP in n8n, you need to create a new **OTP Credential**. 2. **Enter the details in the Credential** - **In the Secret field:** Enter the **secret key** (extracted from the QR Code link). For example: ``` test-test-test ``` - **In the Label field:** Enter **ServiceName:username** For example: ``` OpenAI:amir676080@gmail.com ```  3. **Save the Credential** After entering the information, click Save to save the Credential. ## Step 3: Get the OTP Code **Click on Test Workflow** After setting up the credentials in n8n, click on Test, and the corresponding code will be delivered to you. Output: ``` [ { token: 720769, secondsRemaining: 18 } ] ```  **This code is exactly the same as the one generated by apps and services like Google Authenticator or Authy.** Contact me on [Telegram](https://t.me/amir676080)
