How do I re-enable getting a phone call as double authentication?

On one computer I checked the box that said "I often use this device so don't phone for authentication" but now I would like to change that. I would like to re-enable the double authentication for that device, thus requiring not only my password but a code delivered by phone. Can I do it? How? Thanks!!
