Two-step verification, or Two-factor authentication (i.e. getting a code on your phone to sign-in), adds an important layer of security to your account. I have this set-up on my Google account. I didn't notice this until recently, but Naver (네이버) also lets you enable this security feature, though they refer to it as OTP. With all the hacking stories out there, it's useful to "set it and forget it." It's pretty simple if you're already familiar with 2-step authentication, with one main difference: the Naver app itself is used for generating the codes. But we'll get to that.
Creating a Naver Account
The brilliant thing is that 90% of all this process can be done in English. Creating a Naver account and editing all major account settings on Naver can all be done in English (and Chinese), even though most Naver function beyond that are only in Korean. No Alien ID Numbers (외국인 등록 번호) or passport numbers are needed; but you will need a mobile phone to receive a verification code. I was required to enter a Korean (+82 prefix) phone number, but when signing-up from abroad, you can choose from an international country drop-down list.
Enabling the Protection
Once you've created your Naver account (and it really is super simple), we can enable the Two-step verification.
like Google's) is that the codes will be generated within the Naver App itself, not using a seperate stand-alone app (like Google Authenticator) nor by SMS text messages. That last fact is strange, considering that Naver will use an SMS message code to verify your phone number here. Why not just have an SMS option for receiving codes?
Part of the reason may be this:

Note also here that the phone number you use here does not have to be the same number associated with your account (the number you gave when signing-up with Naver). For example, I didn't want to install the bloated Naver app, so here I used the number of a family member who does have the app. It worked just fine, though of course I'll need that person's phone when logging-in on an unknown/untrusted computer. Input the number, Naver will send you an SMS code, and input that code here.
Android - iOS) to your phone, if you haven't done so already.
If you're not sure where to get this code, I'll show you now.
Now back to the set-up:
This could be really annoying to do every single time, so don't be a chump. If you're on your personal computer, just be sure to click the "Stay OTP Signed in" checkmark button before entering the code, and you won't need codes for that computer anymore. Set it, and forget it. Enjoy the peace of mind of knowing that no other computer will be able to log-in as you.
Hopefully you found this guide helpful. Though, of course, nearly the entire process was in English so really such a guide is a bit unnecessary. Personally, that makes me glad, that Naver expands their English offerings. Naver's services really are useful and powerful; not just "Korean Google". I think they could see a lot of expansion and growth by supporting even just a few foreign languages (English / Chinese / Japanese). As I wrote before, Naver Dictionary and Naver Translate can be used fully in English. Let's hope more Naver services continue to become multi-lingual.
