Is there any way to hide channels from other channels on the same account?

Like it’s possible with yt…

No… yes…?

What do you mean by «hidde channels from other channels» ?

You know how multiple channels can be created under one account… if people click on the account’s name they can see them all, though…

yes, and?
Still not sure to understand the question. On peertube, channels are public.

So, the only way to have multiple channels hidden from each other is by creating multiple accounts?

I don’t understand what you are calling «hidden from each other».
Channels are public, and associated to one user each.
If you want multiple channels, and nothing that relates 2 channels, yes you have to create 2 accounts.
