Want to watch an age-restricted video? but can't log in because you're at work, school, or simply don't want to create a Google account? You don't need an account to watch age-restricted videos. All you need to do is make a small change to the video's URL (address). This will not work for videos that have disallowed embedding on external sites.
Method 1: Change the video URL
Look at the video's URL in the address bar.
Find the watch?v= part of the address. Highlight this part and replace it with v/. (see screenshot below)

Example if the video address is You do not have permission to view the full content of this post. Log in or register now. then change it to You do not have permission to view the full content of this post. Log in or register now. AbcdEfG123

Method 2: Add nsfw to the beginning of address

Load the video or press enter.

Thats it
