Client environment needed for this

Mission: USER ROOKIE
Task: Login user with API

I wonder if I can complete this mission without the need of having a client environment?
I am still waiting for the plugin for my environment to be updated/made.

I have understood, that, I by obvious reasons, cannot do it in the REST console. (I have now finally understood its purpose)

Sadly I am not proficient enough in Javascript to do temporary workaround.

Maybe you have suggestions of temporary service or solution I can use now meanwhile?
(that will not lock me to it)
Thanks.

There are several ways to complete this without coding:

  1. You can actually do it in REST Console:
  2. You can do it in Server-side Business Logic (Cloud Code)
    Here I declared a method that 2 arguments (username and password) and used Codeless in the implementation to login the user:
  3. Using UI Builder - there is a page template just for login:

    the created page has all the UI and logic for it:
