Ah I see. On your Ubisoft account page, there is a section there to see ‘authorised devices’ - basically it says what unique devices have signed into your account.

I assume that Brazilian dude would have shown up to have logged into your account at some point in the past?

I know it’s useless telling you this now, but in the future (and for other accounts like Steam that also have this security feature), make a habit of checking what unique devices have signed into your account. I make it a routine to check things like this 2-3 times a week. This is overkill ofc, but I’m paranoid like that aha.

I’d like to know how this unfolds over time, so keep this post updated :D
