Sometimes, while watching youtube videos, we need to sign-in to watch some videos, most of them are adult content, but that doesnt mean we gotta create an account just to watch a video or so. So heres the trick to get things right.
Suppose there is a video. Example as
http://www.youtube.com/watch?v=Q4WnNo4VE1I
Try hitting the above url and you will be asked to login by youtube. Go on..
Now you have seen clearly that above video requires login or signup.
Now we want to bypass that login or signup requirement.
Now we want to bypass that login or signup requirement.
All we gotta do is edit the url, that is replace the ? and = both by / and hit the url
http://www.youtube.com/watch/v/Q4WnNo4VE1I
^ ^
From the error page, it would be like this
Url of the error page
http://www.youtube.com/verify_age?&next_url=/watch%3Fv%3DQ4WnNo4VE1I
Remove verify_age?&next_url=/ from the url
And Replace %3F and %3D by /
Look
http://www.youtube.com/verify_age?&next_url=/watch%3Fv%3DQ4WnNo4VE1I
http://www.youtube.com/verify_age?&next_url=/watch%3Fv%3DQ4WnNo4VE1I
/ /
/ /
Resulting url:
http://www.youtube.com/watch/v/Q4WnNo4VE1I
That's the end and you will be able to see video without login or signup.
