Are the router account and password broadband accounts and passwords?

no, take Henan customers as an example. Generally, the broadband account number is a mobile phone number bound to broadband, and the password can be reset by sending a short message "CZKDMM" to 186. The router account number and password are set by the customer himself.

in view of the differences in business rules and tariffs among provinces, you can call local 186 for consultation.
