Overview
This node enables Two-Factor Authentication (2FA) for a user by verifying a One-Time Password (OTP) against a provided secret. It is useful in scenarios where enhanced security is required for user accounts, such as in administrative panels or applications handling sensitive data. For example, after generating a 2FA secret for a user, this node can be used to confirm the setup by validating the OTP generated from that secret.
Properties
Name | Meaning |
---|---|
OTP | The One-Time Password generated using the 2FA secret, used to verify the user's 2FA setup. |
Secret | The 2FA secret key previously generated, used to validate the OTP and enable 2FA for the user. |
Output
The node outputs JSON data representing the result of the 2FA enabling process. This typically includes confirmation that 2FA has been successfully enabled for the user or an error message if verification fails. There is no binary output.
Dependencies
- Requires access to the user management system or API that supports 2FA operations.
- Needs valid credentials or API authentication tokens configured in n8n to interact with the user service securely.
Troubleshooting
- Invalid OTP or Secret: If the OTP does not match the secret, the node will fail to enable 2FA. Ensure the OTP is generated freshly from the correct secret.
- Missing Required Fields: Both OTP and Secret are mandatory; missing either will cause errors.
- API Connectivity Issues: Network or authentication problems may prevent the node from communicating with the user service.
- Time Synchronization: OTP generation depends on time-based algorithms; ensure server and client clocks are synchronized.
