# How-to guides for MFA

Multi-factor authentication provider registration is crucial for system security, ensuring that only authorized users can access sensitive data. MFA requires users to provide two or more verification factors, such as password, security token, or biometric data.

Attention

If you already have an MFA provider registered in your account, registering a new provider will deactivate the previous one.

Each authentication method has its own registration and usage guide, as each provider offers distinct functionalities and requirements. After selecting your MFA authentication method, follow the instructions according to the guide corresponding to your chosen option:
