API Requests- Authentication

[OrestisIon]

Hi,
I am using Miniflux as an API for my RSS-reader project. I was wondering if there is a way to authenticate without using the token? I know there is username and password authentication but that is HTTP and is not secure for my case. What I was looking to find is a way to create an API token for every user and store it in an external database but that would require to have an HTTPS request to generate token which I can't find. Any help would be appreciated
