When a new device or browser signs in to your Dropbox account, you’ll get an email right away with everything we know. To figure out if this was you, take a look at the email:
We send you an email the instant a new device or browser signs in to your Dropbox account. So check the date in the email and the time we sent it. If you weren’t connecting to Dropbox at this time, then that’s another clue that this might have been someone else.
You’ll also see the device (Mac, Android, iPhone) and maybe the browser (Chrome, Internet Explorer, Safari). If this device or browser isn’t one that you usually use, that’s another sign this might not have been you.
If you think this might not have been you, or even if you’re still not sure, then the best way to keep your account secure is to update your security settings right away.
