Authenticate user while still following privacy settings

[jl-678]

Describe the bug
I am running Microbin publicly and want to set it up to allow me to create links and use all the privacy options while also providing user authentication to prevent random people from using my instance. I would expect that Microbin would allow me to authenticate myself as a user and then enable me to create public pastas.

User authentication locks down site access for everyone and effectively making my pastas inaccessible. So even when I create a public pasta, clicking on the link in an incognito tab brings me to my Micronin instance asking for username and password. As a result, it is not possible to create public pastas when user authentication is enabled. Is this expected behavior?

To Reproduce
Steps to reproduce the behavior:

1. Enable basic user admin and password
2. Login to Microbin, create a public link and copy the link
3. Open incognito and try to access the link from 2
4. Result: You cannot access the pasta and instead are forced to login

Expected behavior
Login should be required to create a pasta, but once created, the pasta should follow the "privacy" settings in Microbin. (e.g. You can login and create a public pasta and it will be publicly accessible to anyone with the URL.)
