Not entirely sure what the link got changed into an accounts.google.com link, it's supposed to be just https://www.youtube.com/handle

I'm not logged in right now. What is this about?

Currently your channel name is like youtube.com/<randomstringhere> or if you had a youtube account for a while it's like youtube.com/c/channelname or youtube.com/namehere if you're really big. They're throwing that all out the window and go with tiktok-style handles like youtube.com/@yourname. All old names and urls will still work.
