Got new Samsung S20 phone. It says incorrect password.

[Gogsi]

I've had a Samsung S9 for 4 years and all has been working fine.
Just bought a new Samsung S20 and, although I can access internet on both my Laptop and the S9, the new S20 says incorrect password after I choose my Sky Wi-Fi Network.
   I have triple checked to make absolutely certain that it's the correct password but, the new S20 tells me it's incorrect.
    Quite frustrating having a new phone and unable to use it : (
        Thanks so much for any hellp given.

Duuuuhhh !      Operator error !  

The password I was using was not the one on the actual router. It may have been like My Sky ID or similar. Anyway, got it sorted and am looking forward to getting to know my new phone !
