Does anyone know why this is implemented?

As a... – registered user I want to... – check the ‘remember me’ checkbox So that... – I am merely placated by the placebo effect

As a Zoom user, I want Zoom to forget me on my laptop when I sign in on my desktop, so that I can enjoy typing in my details again whenever I switch machines

Usually it affects the expire setting of the cookie. Adding the check to the box will make your cookies last longer. I have my browser configured to throw away all cookies whenever i close it so it doesn't work for me either.

Using a pre-built login form template and forgetting to remove the checkbox is my guess.
