Can the Arduino code be changed over the air?

Hi!
My D1 Mini is on a hard to reach spot, can it be accessed over the air?
I have to make changes on two devices, one I have to clear the credencials as the car will be sold and the other a have to change the node name. Can it be done over the air?
Thanks!

Kinda yes but probably no. If you compiled the code yourself and set the otaPassword, then yes you can use the arduino Over-The-Air flash update mechanism to flash the device. If you didn't set this value at compile time, you'll need physical access to the device.

Thanks a lot!
