@josevidal Xiaomi Mi A2 - Focal OTA 2 - Stable Channel SSH works fine, I don't know if it helps ... try disabling usb-moded-ssh service, on my device is disabled.

I got to the point where is asks for a password but won't accept my password. Word of caution: don't change your password from command line if you've enabled passcode - when you phone locks it only gives you a numpad to enter your password, not a keyboard.
