Auto authentication you no need login for access inet but only read IP/MAC
Password authentication, you need to login first for access inet, but Sangfor device can see who is login.

Password authentication requires the user to manually enter a secret password, which is checked against a stored value to grant access. It relies on the user remembering and securely managing their password. Whereas; auto authentication, often involving technologies like biometrics (fingerprint or facial recognition) or single sign-on (SSO), automates the authentication process by using inherent traits or previously established credentials, providing quicker access without the need for manual input. Auto authentication is generally considered more convenient and secure, as it reduces human error and the risks associated with weak or reused passwords.

In Sangfor IAG, auto authentication logs users in automatically using methods like SSO or device recognition, offering seamless access and convenience. In contrast, password authentication requires users to manually enter credentials, providing simplicity but less convenience. Auto authentication is ideal for trusted environments, while password authentication suits untrusted or shared devices.

On auto authentication device will identify users based on the source Ip address, source MAC address and hostname of endpoints while password authentication is based on username and password created.

Auto: No login needed.  
Password: Manual login required.

Passwords are considered the most common and basic method of authentication. It uses a string of letters, numbers, and special characters. Passwords are usually paired with usernames. This combination will be recorded, and future inputs of username and password must match with what is recorded by the system.
Authentication is the process of verifying a user or device before allowing access to a system or resources.

Auto Authentication: This method facilitates user authentication without the need for manual entry of credentials, relying instead on predefined criteria such as IP address or MAC address. It is typically utilized to ensure seamless access for recognized individuals or devices.

Password Authentication: This technique necessitates that users enter their username and password manually. As credentials are verified prior to granting access, this method offers a higher level of security.

In auto authentication the user is authenticated after binding the IP or MAC, he can access the network without authentication. In password authentication the user enters his username and password through the local password authentication method to authenticate.
