@BastropGuy,

Unfortunately, the feature doesn't exist due to the fact that your devices would need to be connected to the network to communicate with your phone in the first place to receive the new password. Have you had a smart plug in the past that could do these batch password changes? 

I believe that there are new methods of doing this due to the matter protocol's use of Bluetooth Provisioning, but the Matter protocol is still in its infancy and the feature is not widely rolled out at all. Saying that, I do believe that our latest smart plug actually implemented BT provisioning and a BT chip, making the process far easier than before.

Instead of using your main wireless network, many users are electing to place the devices on the guest or IoT network. This would minimize the effects of any breaches, should one occur on your network - and will also allow you to change the password of your main Wi-Fi network while keeping the network for your IoT devices the same.
