If you have a Google account - it is worth your time to do a security checkup by clicking here or going on to Google and type in "Google Security Checkup".
The checkup will...
check on your recovery information (e-mail and phone)
check your connected devices - and let you know when they were connected
check your account permissions (apps, websites, and devices connected to your Google account)
check your 2-step verification settings (very important)
Hope you all have a nice day!
