Hi Laurie - You sure can!

You can access Grokker on your personal computer by connecting your computer to Aetna's VPN and logging in normally. Once you've logged in for the first time you can access Grokker without VPN at your home. If you need further assistance please email us at support@grokker.com

Cheers,
Britteny
