A Microsoft file hosting and synchronization service.
Thank you very much James for your 12Feb24 post. Skype is another example of a Microsoft app.
When I received my unusual request from Microsoft when restarting my Samsung Galaxy phone I became so scared because I did not know my Microsoft registered email address.
I tried two email addresses, but Microsoft then sent a code to each in turn, and I had to use my laptop to get it because I assumed I couldn't open the email app on my phone.
At that point I nearly freaked out at the thought of this happening again during one of my frequent trips to a remote location where I rely solely on my phone for communication and for access to a huge amount of my personal information, and don't have my laptop with me.
But now, having correctly guessed the email address (and discovering that I had not just one but three Microsoft accounts!) now Microsoft was requesting a password and I couldn't remember it. Then I noticed Microsoft was offering to send an email to my backup email address, but because I haven't used it in years I couldn't remember how to log in to its webmail on my laptop.
At this point I realised I didn't actually want to log in to Microsoft. Similarly to banking, I rarely risk logging in to faceless organisations on my phone. I felt stuck, until I explored the possibility that Microsoft wasn't actually blocking my use of my phone, and it turned out that it wasn't. So now I wonder why Microsoft had to ask me to log in at all. Your post has explained it, James. Thank you again!
And my indignation with Microsoft has dissolved, as I realise they were simply checking that a stranger hadn't stolen my phone and might be using my Skype to continue illegal activities. So thank you Microsoft, too.
