How do I delete an old device from my Google Acct? so I have given my old phone to my mom and have forgotten to remove the my gmail account. I want to delete the phone from the "approved" list but I cannot find a way to delete it.

I've looked at various guides and the options/settings they are talking about are not available anymore.

I am looking at this page: https://myaccount.google.com/device-activity

Any ideas?

I'm trying to avoid changing my password since that means I need to change that on all my devices.

Thanks
If you are unable to remove the device from the Device activity section of your Google account because the red button doesn't show up, go instead to Google Security Checkup and expand Your devices, then tap on the 3 dots on the side of the device you want to remove to select the option.
