New iPhone

Hello I have a new iPhone. When I want to use “DUO” 2-way authentication app I see I must reconnect Bitwarden. After clicking reconnect I am asked to scan QR code or enter activation code
But when I go to the Bitwarden website , there I am asked the code generated by DUO. So I can’t enter my account on Bitwarden.

I can use Bitwarden (free account) on my MacBook app and iPad app, but no longer I can acces Bitwarden website account (because DUO first needs to reconnect , but this can only via the bitwarden website).
