Is there an user-friendly way to authenticate users to my Azure API without having to pass a subscription key or token?

I currently have an API in Azure APIM that requires authentication through submitting a subscription key through the header/url of the API. One of my requirements is that I make the API as user-friendly as possible, as less tech-savvy individuals are going to use this API. I want to remove the need to input a subscription key, and rather just have the users sign in for user-friendliness.

I have not gained access yet through my company to create an Azure AD B2C tenant, however through research (and previously asking asking here) I thought that using Azure AD B2C would be my solution. From what I understand with B2C, users need to obtain a JWT token using their login information and use this token to authenticate themselves with the API. The issue is that it's still not very user-friendly for people who aren't used to dealing with keys and access tokens.

I was wondering if there was a way to authenticate users when they try to access my API without providing some sort of authorization token/key, with just a simple login system. Also if my understanding of Azure AD B2C is incorrect please let me know as I am still very inexperienced with it.

You can remove the need to input a subscription key while calling an API in APIM as below-

If you want to use any Product but don't want to use the subscription key authentication, then uncheck the subscription key option from that specific Product.

> Automatically enable the user sign-in to the API management using Azure AD

Please note, once the Azure AD provider is enabled, users in the specified Azure AD instance can access the API in the APIM using an Azure AD account. Refer this github link for more details.
