My smartphone seems to know who I am. I never signed into YouTube ever. I
had this Galaxy S for one year and it signed me into Youtube and knew my
various subscriptions. How did it do that? I use unique passwords for most
accounts. I don’t see this happening unless some clandestine spying something
is going on. My record is totally clean. Thanks.
In this excerpt from
Answercast #66, I examine a mysterious instance of a phone logging its
owner into YouTube.

No, there’s nothing clandestine going on here. What it boils down to is: I’m
guessing that you have, somewhere, logged into your Google account. In other
words, in using your Galaxy S (which I believe, is an Android based phone), at
some point, you’ve entered your Google account into the phone.
Well, guess what… your Google account? It’s your YouTube account! In fact,
when you sign on to your phone, you probably end up using your Google account
for things like email; probably your contacts; and maybe even your calendar. I
know I do all three.
Google shares accounts
As it turns out, that account can then be used by your phone for any Google
owned property that happens to use the same account sign-on technology.
And guess what? YouTube is wholly owned by Google. And that means that
whenever you go to YouTube, you’re logging into a Google property.
Or the other way around: if you’re already logged into a Google property
(like Gmail) then you’re effectively logged into YouTube, and your phone can use
that information to personalize your YouTube experience to what you’re used to
on your desktop.
So that’s all that’s going on here. There’s nothing underhanded, nothing
hidden behind the scenes. It’s simply a matter of the side effect of the fact
that your YouTube account and your Google account are the same thing and you’ve
probably already logged into your Google account on your phone.
