Nintendo recommends its users to use the 2-Step Verification to prevent unauthorized log-in to their accounts. The 2-step verification method can prevent your account from hacking.
Why Nintendo recommends the 2-Step Verification
The 2-step verification method will help you prevent from hacking or stealing. If you set this method, no one would be able to access your account without your permission.
A few years ago, Google introduced the 2-step verification method which helped so many people in preventing their accounts. After Google, there came Facebook, Twitter, and other social media networks. Now Nintendo wants its users to use this method.
When you set up the 2-step verification method, you will need to enter an Email Address then the code will be sent to the written Email Address. When you enter the code your account will be opened safely. Suppose a third party tries to access your account when they will enter the Email Address and Password, the code will be sent to your Email Address and they will not be able to get that code. This way you’ll know that your account is being opened by someone.
