I know my password, but for some reason I can't sign in. So then I have to change my password constantly on Youtube. -____- It's getting real tiring.
Can't say I'm having that problem at all ... make sure your caps lock isn't turned on when you enter your password - that is actually one of the leading causes of failed login.
I never do either but one day it signed me out of all my social stuff :/
I never sign out of youtube haha.
Someone might be hacking you ?: P
