Can someone explain youtube handle?

the @name for a youtube channel, same idea as an instagram handle. it goes in the channel url, it's what people type to tag you in comments, and it shows on shorts. one per channel, has to be unique. set or change it in youtube studio under customisation, basic info. match it to the brand's other handles if it's free. you can only change it a couple of times in a fortnight so don't experiment.
