PPPoE stands for Point-to-Point Protocol over Ethernet. It is a networking protocol that allows a device to connect to the Internet through a broadband connection by authenticating with a username and password.
A PPPoE username and password are credentials that are used to authenticate a device when it connects to the Internet through a PPPoE connection. The username and password are provided by the Internet service provider (ISP) and are typically required to be entered in the device's network settings when setting up the PPPoE connection.
Once the device is authenticated, it can establish a connection to the Internet and access online resources. The PPPoE username and password are usually only required when the device connects to the Internet or when the connection is lost and needs to be reestablished.
