This scammer uses craigslist to create an ad for an apartment rental. When you reach out to them, they text you that they will call you from their google phone and they need to send you a code. Then you get a google voice code that the scammer wants you to send to them. Im not sure what access the scammer can get with that code, but you should never share that info with anyone.
I did a small background check and found the actual property management company who confirmed this is a scam.
