The used smart speaker still greets someone who does not live here

I bought a used smart speaker at a neighborhood yard sale for $12. The seller said it had been reset. When I plugged it in, the device greeted someone named Chris.

That was enough to stop the setup.

I did not know whether Chris was the seller, a family member, or the previous owner before them. The speaker could not complete normal setup in my account, and one screen suggested that it might still be linked elsewhere. I had no interest in exploring what commands or information remained available just because the device was in my kitchen.

The seller offered to send me their login so I could remove it. That would have created a second privacy problem. Instead, I asked them to use the maker's official account controls to remove the device remotely, while I kept the speaker disconnected. After that, I planned to follow the exact factory-reset instructions for the model and set it up as new.

If the device remains locked to another account, the $12 bargain may simply be unusable. Returning it is less exciting than “finding a workaround,” but ownership controls should not be bypassed because a yard-sale transaction was informal.

The experience changed how I think about used connected devices. Physical possession is only one layer. Account ownership, stored settings, microphones, cameras, subscriptions, and reset behavior all matter before the device joins a new household.

What should buyers and sellers verify before transferring a smart speaker, camera, watch, or hub? Which signs mean “pause and contact the previous owner,” and which mean “return it rather than troubleshoot around an ownership lock”?
