Hi.

I had a strange problem: my brother has no reddit account but when he browse the site on his PC and mobile he finds himself logged in with my own account and even if he just log out it will automatically log in the next time.

The strange part is that i've never used his PC/mobile in my life and barely use my main account at all (mostly 1 time a day via reddit mobile app) and the only thing that we have in common it's the home wifi but i have no idea how my account got into his devices in first place.

How can i solve this situation?

(note that this account is a fake one for lewd purposes, i get here only via incognito mode but now i fear that the problem might happends even with this one, that would be an horrible situation)
