I am a beginner, I wanted to make that clear from the start

Hello,

I am a beginner, I wanted to make that clear from the start so please don't ASSUME I know anything about wordpress or coding. Thank you in advance.

I set up a multisite in so doing the login somehow was disabled I tryed to enable it by going to settings which I read on the internet was how to enable it. Sadly I could find nowhere to do so, can you help? There is no login visible to access my site I go to mysite/wp-admin and it remembers me lucky for me.
