Q&A for How to Use the Internet Archive's Wayback Machine

You can't sign in to websites on the Wayback Machine because it only archives the front-facing architecture of web pages, not the back-end systems that manage user accounts.

When you save a page to the Wayback Machine, it saves the "face" of the web page, basically what you see when you visit a web page. It does not capture the internal workings of the site, so features like videos cannot be played.

Some things may not have been archived or cannot be archived, as such you cannot view certain parts of a website, (i.e. flash content, sign in screens, etc).

No, you cannot watch a deleted video on the Wayback Machine if it was not archived. While the Wayback Machine saves snapshots of web pages, it does not guarantee that all embedded content, like videos, is captured or playable. Your best option is to search for the video elsewhere online using its title or descriptive terms.

You need to copy the link to your current YouTube channel, which can be done by going up to the search bar on the top of the web browser, pressing CTRL+A, then pressing CTRL+C, then bring it to the Wayback Machine, CTRL+V the link in the URL box, then select 2013.

As long as the browser supports it, then it will be work the same way as outlined in the article.

Usually instantaneously, but if there are issues - it can be from a few hours to never.

The oldest page archived was on May 12, 1996, and it was infoseek.com. So that's the furthest you can possibly go.

You cannot view deleted YouTube videos on the Wayback Machine; it typically doesn't archive video content and may only display an error message or limited metadata.
