For now Opera for Android (74.0.3922) doesn't support default Android AutoFill feature thus not allowing to use password managers like Bitwarden, KeePassXC or Lastpass.
It is quite inconvenient. I for example use KeePassXC on multiple platforms - Windows, Linux and Android, so it's very important to be able to use the AutoFill feature in Android browser as well.
Please add support for this
