Not sure I understand. Unless you're counting the user's modem / router as part of their internal network. The same DSL network authentication, system generated, 6 char PW, has to be manually entered into my router. The router has to resend the PW every few min to keep a connection, of course. I don't consider my router part of their system.
I don't think I understand your exception, or your concern. The DSL network password is used to authenticate the PPPoE session. The authentication server is a part of the AT&T network. The DSL network password does not go beyond the authentication server; regardless if the PPPoE session is established on the modem, or a router, or computer behind the bridged modem; it stays internal to AT&T.
By contrast, the e-mail password leaves the AT&T network to traverse Yahoo! transit en route to the mail server.
Until some time in 2008, or 2009, my DSL network password was the same as my primary e-mail account password. This was common back to 2001, when I established DSL service with Pacific Bell (which was owned by SBC, but still allowed to bill as, "Pacific Bell" at that time).
Probably subsequent to the AT&T purchase of Bellsouth, AT&T set up the separation of the DSL network password and the e-mail password. A relative had the bad habit of using the same, simple password for everything, and had an MSNIA account stolen. I knew I would be changing her passwords, and decided to experiment with requesting a DSL network password reset on my system, to see how I would implement the change for her (she is an 'at&t Yahoo! HSI' customer).
Separating the two means you don't have to remember to change the DSL network password in the modem/router/gateway every time you change the primary e-mail account password.--
