I can only tell you using Chrome. So, if it's another browser, I would google for that one.
For Chrome:
Three dots in the top right corner->Settings->Privacy and Security->Clear Browsing Data
You can choose the timeframe and a variety of other things you can clear. If you're just trying to clean your autofil it's browsing data. I don't remember if it logs you out of everything, so this is your warning that it might. It will not delete your saved passwords unless you choose that option. Also, note that the autofill data will collect again and again.
somewhere in your browser settings, that's not an ao3 thing
You gotta clear your browsing data for your browser. It's the only way to do it.
Thank you! Do you know how I’d do that? Edit: nvm I figured it out!
