PPPoE credentials, from English “Point-to-Point Protocol over Ethernet” and in Spanish, “Protocol Point to Point over Ethernet”, are a series of authentication data that Internet service providers (ISP) ask users for. to be able to connect to the Internet access network.
It is a protocol that provides the possibility of encapsulating point-to-point connections within Ethernet frames and offers a very efficient solution for managing connections using DSL or even fiber optic lines, whether for home or business purposes.
PPPoE differs from common router configurations because they require a username and a particular password provided by the ISP.
Likewise, this authentication is essential because it confirms that you are really a registered customer, which grants you access to the broadband network.
PPPoE also facilitates direct and even more secure connections in transmission networks such as Ethernet since it combines the features of a dedicated protocol (PPP) and a wide broadcast network.
Precisely, this integration is what allows ISPs to both manage and administer user access in a more effective, efficient and secure way.
How PPPoE credentials work
The process begins when a device, which may be a router, sends a request packet called PADI (PPPoE Active Discovery Initiation). This identifies the presence of an ISP access server (AC) on the network.
The ISP’s access server then provides a response with a PADO (PPPoE Active Discovery Offer), which contains details about the available service. It is there where the router proceeds to identify the server with which it will make the connection.
Then the router sends a PADR (PPPoE Active Discovery Request) to the chosen server and thus confirms that it wants to execute the connection. For this to be established properly, the server has to send a PADS (PPPoE Active Discovery Session-confirmation), which finally performs the PPPoE session and places a unique session ID, which remains intact until the connection is closed. .
Once this process is done, it will be necessary to authenticate by entering the username and password given by the ISP. If the verification is unsuccessful, you will be denied access to the server and must correct the information. Of course, you should not make more than three failed attempts, as there may be blocking policies to prevent unauthorized entries.
How to get PPPoE credentials
To obtain your PPPoE credentials you must request technical support by telephone or online from the company that provides you Internet service (Movistar, Yoigo, Jazztel or any other) so that they can provide you with your username and password for a new or neutral router.
Generally, they will provide you with the data after verifying your identity. However, there is a possibility that they limit their use only to the routers offered by the company.
You can also check your operator’s website, as some have sections where they post guides or tutorials for configuring neutral routers. Additionally, if you have your service contract documents or the router box you can check to see if the PPPoE is there.
And although it is also possible to obtain generic credentials on the Internet, it is not recommended that you use them because they are not secure. It is best that you manage the request with your Internet provider, who will be the one who guarantees both access and security in your connection.
