use squarespace-server with different squarespace accounts locally

When I start up a page locally 'squarespace-server url --auth ' it keeps using the authentication for my other account and I can't seem to be able to re-authenticate.

I've tried uninstalling the npm package, cleared my keychain and restart my computer but nothing triggers re-authentication.

Does anyone know how I can work on two different websites with different squarespace accounts? I tried searching through the sub but I couldn't find any answers

I'm on a Mac and I have to use --auth since my own page is a free trial which I'm testing stuff on before doing work on my clients page.
