TC4400-AM default username/password?

Hello, I upgraded to the 940mbps connection. Videotron replaced my modem with the Technicolor TC4400-AM.

According to: https://www.router-reset.com/reset-manuals/Technicolor/TC4400

The default username and password should be admin/password. I have done the 30/30/30 reset, and I still cannot login to the modem. Has Videotron locked down the modem? How can I login?
