@leocg It only lets me enter my password, my username automatically appears, I don't see any option for Forgot your password?

Hello Neorz Tormeno!
Confirm your identity
For security, we need to confirm your identity to allow synchronization. Enter your Opera account password below.

There is no "Forgot your password" option and the support AI is useless.
