Signing out of gmail. It seems tied to the OS.
It's been years since I wanted to, but for various reasons, having changed the password, I can't seem to simply sign of my mail and test the new password.
It seems in some way tied in with the OS and in particular, the signing into W10 on another computer of mine which is at another address.
It all started when my friend found she couldn't get into the PC without verifying the gmail. She has no need to access my mail. Changing the password seemed to overcome the problem. I am utterly bewildered and indeed unsettled by this oddity. It's clear I'm very vulnerable to being left out in the cold. It happened with Skype when my paid subscription was cancelled without any option to explain. It seems it objects to quick redialling - one of its major benefits if you ever want to get through to a doctor.
