In a scenario where my esp32 is an access point, it is possible to verify the password of an ssid in range of my access point? The idea is, before to switch off the esp32 access point and to connect to an already existing ssid, to verify if the password is ok.

Most likely no because you would have to either perform a handshake or observe a handshake. What would be the advantage over apsta mode? You would still have to switch channels.

You would try to connect in APSTA mode and if you see a successful WIFI_EVENT_STA_CONNECTED event you can turn off the AP.
