In order to run these tools you will need a number of session cookies: SSID, HSID and SID. Log into YouTube with whichever Google account you want to use (preferably not your primary one)
In order to run these tools you will need to provide "session cookies", you can think of this as a lazy way of logging onto YouTube:
- In a new/guest/Incognito browser profile, create a test Google account.
(Use a separate browser profile so the cookies don't get associated with your main Google account).
- **IMPORTANT: Set the default account language to English (United States). https://myaccount.google.com/language**
- **IMPORTANT: Visit YouTube.com. Set the YouTube site language (found by clicking on the profile image on the top right corner of youtube.com) to English (US).**
- Open developer tools and go to the Application tab in [Chrome](https://developers.google.com/web/tools/chrome-devtools/storage/cookies), or the Storage tab in Firefox. Click on Cookies and then https://www.youtube.com. Copy the full values for the following cookies on youtube.com: HSID, SSID, and SID. Note these values for when the archiving begins.

The cookie values are needed because a Google account (any Google account) is required to access the community contributions editor, where much of the data is gathered from.
