Advice on wiping a sold phone remotely.
I had a pixel 7 that randomly died whilst on charge. I was due an upgrade anyway so cut my losses with repair and just upgraded. I then sold the pixel 7 for spares. I didn't think about my personal data at the time. But now the buyer has managed to get it working and asked for a pin to reset the phone. I am not comfortable giving this to them. Chat gpt told me to log out of my Google account, great advice, only it then told me i needed to be logged in to reset the device remotely I'm a little screwed.
I've tried looking for guides and other advice but nothing really covers my scenario. What are my options?. I don't want to ghost them as that feels harsh. help if I can, I guess they can bring the phone to me and unlock and wipe in person. But if I can save them the journey then I will. Thanks.
