When viewing the container in the portal and it says "Authentication method: Access key" this only applies to your user that is currently logged in. Since I am assuming you are an admin account you will be able to access the storage access key and view/upload blobs from the portal. Think of the toggle in the portal as the difference between using --auth-mode login and --auth-mode key in the CLI. Anyone with a storage access key will be able to modify container data just like anyone with the proper role assigned will be able to. Toggling the authentication method in the portal will not change this.
Hopefully that helps clear this up. Let us know if you have further issues or questions and we will be happy to help.
