For my last couple of stays, somehow in room wifi no longer ask for authentication (room number - last name)

So when connecting to the hotel wifi network, both my laptop and mobile phone show a different landing page.
Instead the usual one asking for room number and last name, it straight show welcome (members name) and information that it was connected to their premium wifi or whatever wifi they have.

The same happens when I visit a Marriott hotels and not stay with them.

The hotel I experience this are :
St Regis Nusa Dua, Fairfield Legian, The Ritz Carlton Mega Kuningan, and W Seminyak (I only visit their bar on W Seminyak)

I did stay at St Regis Nusa Dua and The Ritz Carlton Mega Kuningan previously but I never visit either W Seminyak or Fairfield Legian.

(Interestingly it happens with Accor hotels portfolio as well)

Does Marriot somehow centralise their authentication services and recognise the devices?
