@YouTube - Hi there, I have a very old account that I can no longer access (for some reason the email login doesnt work? It is very old, perhaps from a time when usernames were used instead) but I want to access the account and delete it. How can we arrange this?
If it's a legacy channel, you need to link it to a Google Account to access it. Here's how: https://yt.be/help/Bdho . Also, if you don’t remember your old YouTube password, unfortunately there is no password recovery option for these accounts.
