Everyone can see my password!

Well, It is partially my fault. I entered my password right next to my username in the twitter sign in page. and now each time i open up the twitter page through Brave browser, my password is there. I deleted it from the browser password options and even went to the extent of uninstalling and reinstalling my browser. This is a temporary work computer and i will have to leave it in a month or so and someone else might use it. How do I fix this. I NEED HELP. :frowning:
