Regarding forgotten username and password

[Bhathiya]

I forget my user name and password. I wanna change the password of my router

Hi @Bhathiya

What type of username and password have you forgotten?

Is it your account username and pw or your modem/router login?

What password would you like to change to your modem/router?

Is it the WiFi or the admin password?
