Can my users search Spotify without logging into their own account

Hi all, I’m new to APIs.

I am using the Spotify Complete plugin to allow users to search Spotify tracks and add them to a collaborative playlist.

I use the “login through a social network” to do the authentication.

However, I want users ideally to be able to do this without logging into their Spotify account. They shouldn’t need to as I’m not altering anything on their account, they just need to be able to search.

The search doesn’t seem to work without authentication, and I’m guessing authenticating them with my account isn’t possible, or is a security risk.

Is there any way around this? I imagine there must be a way people can search spotify tracks through an API without logging in?

Thanks in advance
