Validate OP Token (without creating a credential)

## OTP Validation with Function Node This template allows you to verify if a 6-digit OTP code is valid using the corresponding OTP secret. It can be used in an authentication system. The inputs need to be: - a base32 TOTP secret (String) - a 6 digits code (String) **Important:** The 6-digit code must be in text format. If the code starts with zeros and is treated as a number, it could cause validation issues. The function node will generate a 6-digit code from the OTP secret, then compare it with the provided code. If they match, it will return `1`; otherwise, it will return `0`. ## Example usage: - You retrieve the user's OTP secret from a database, then you want to verify if the 2FA code provided by the user is valid. ## Setup Guidelines You only need the **`OTP VALIDATION`** node. **You will need to modify lines `39` and `40`** of the node with the correct values for your specific context. ## Testing the Template You can define a sample secret and code in the `EXAMPLE FIELDS` node of the template, then click `Test Workflow`. If the code is valid for the provided secret, the flow will proceed to the `true` branch of the `IF CODE IS VALID` node. Otherwise, it will go to the `false` branch.
