Authorization in google services and accounts.youtube.com

Question

Google

In the authorization process, for example in gmail, there is a temporary redirect to accounts.youtube.com, and then return to mail.google.com.
I want to sleep, because there are only two ideas:
1. Oh, horror, I was hacked! :-D this behavior is observed not only with me, but also "on the Internet"
2. This is necessary for the correct setting of cookies (or whatever) for authorization on all Google services.

Does anyone know the truth, why is this?

Answer 1

I don't go to youtube. I go directly to mail.google.com, remove the strikethrough =)

Answer 2

Don't remove it, it also throws me on youtube)

Answer 3

I think that if your Google Account is linked to Youtube, then cookies are written to *.youtube.com and *.google.com at the entrance

Answer 4

I have seen this myself too. So either I was hacked yesterday too, or something… But the day before yesterday I just turned on two-factor authentication.
