I would like to use my new WYZE window Cam in multiple locations but do not want to to change the SSID and password by deleting the camera and reinstalling it. Would just like to change those two items.
Several cams have gotten a “change network” feature added. Not sure if that is one of them, if you have one set up, check in the app under the camera settings, same spot it shows the wifi signal strength, see if there is a button there.
The safest bet is to have both SSIDs online at the same time so you can do the swap over.
Even if it doesn’t support that feature, you don’t have the delete the cam, just press the button on the bottom to put it into “ready to connect” and go through the setup process in the app. In that case (where the cam already exists in the app) that process only changes the wifi details.
Welcome to the Forum, @ajaqua1! 
If you own or manage the Wi-Fi at the locations where you plan to use your Window Cam, then you could consider making the credentials the same at all locations. If that’s not possible, then you could also consider a mobile hotspot or travel router that uses the same SSID and password as your home. Otherwise—for this Cam at this time—it’s likely going to be necessary to use the Cam’s SETUP button as noted in order to change its Wi-Fi network, and you should be able to abort the rest of the setup after the Cam connects to the new network in order to keep the remainder of its settings intact.
