Mutiple Podcast accounts

I recently was made a host in another podcast platform and I want to know how I can access the space on my anchor app. I tried logging out and logging into the new account but it kept saying invalid. I however was successful with the web version but I need access to the podcast on the app. Also, I would like to be reminded on how to make a podcast visible. The new podcast account has a different password and name and I am only a host who has access via the password. Thank you.
