What protocol should be used when simple username/password authentication is needed?

802.1x
TACACS+
CHAP
RADIUS

Explanation: When simple username/password authentication is needed, use RADIUS to either accept or deny access. RADIUS only encrypts the user’s password from the RADIUS client to the RADIUS server. The username, accounting and authorized services are transmitted in cleartext. When RADIUS is integrated into a product, security measures that protect against replay attacks are necessary.
