I'm assuming you mean the broadband username and password.
Unfortunately Sky/Now don't use a standard PPPoE connection, so it rather depends on if the new router has the correct connection type. Both ASUS and TP-link routers now have it, so just what router have you got?
As @Jayach alluded to there is no PPPoE username and password for NOW broadband. You will need a router that supports MPoA and DHCP option 61. If your router does not support these then you're out of luck.
Or Sky(MER)_VDSL as I believe it's called in the ASUS and TP-Link routers, which really is the easiest way to do it.

Are you saying you want to replace the Now router with the Tenda?
Which exact model of Tenda do you have, as the AC1200 Tenda's I could find are not DSL routers, so can't be used as a direct replacement.
There are many different types of things that are called "routers"
And as for the Now Hub 2 "router" that is technically an all in one device, consisting of:
A DSL Modem
As mentioned above you will need a router with a DSL modem on board, and one that is compatable with Nows MER/Option 61 Log in system Routers compatible with Sky's VDSL services should also work
It say`s on the box, Tenda AC1200 Dualband wi-fi Gigabit VDSL/ADSL Modem Router.
In that case, yes it may be possible to use it on Now. but as previously stated Sky/Now don't use a simple PPPoE connection. Make sure it has the latest firmware and see if it has a connection type that says Sky_Mer or something similar.
As that is not a common router there will not be much info on using them on Sky/Now, so you will be very much on your own on getting it working.
