Q: Why is the Steam Key of Defend Your Life safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Defend Your Life to your game library. The account format requires more complicated steps and is more prone to errors during activation.
