Every time I log in to Google with the same MacBook I get this email:
New device signed in to firstname.lastname@example.org Your Google Account was just signed in to from a new Mac device. You're getting this email to make sure it was you.
What do these emails mean exactly? When does Google send out those emails?
I guess I receive those emails because I use a VPN (always same public IP address) and some privacy plugins in Firefox.
