Hello guys I am boysnoel12,
I would like to share this tip on "how to enable Two Factor Authentication also known as 2FA by using address only" to newbies and other forum members that didn't know how to enable 2FA. To those who already know how can also help (if you want to).
Before I start, You must download and install Google Authenticator in your mobile device. You can download google authenticator in Playstore.1] Open the website where you want to enable 2FA and log in your account, after that open account settings. In my case refer to image below where I can see the 2FA in my accounts settings. My case is in einax website. (Note: I'm not advertising their website and I use it for example only)2] Click the Two-Factor Authentication as shown in image above and you will be redirect to new page where you can see the address needed to enable 2FA. Refer Image below.
3] Copy the address address provided from the website.4] Open the Google Authenticator you downloaded from Playstore. Next, Press the red + sign button.
Next, Click enter a provided key
Enter the name of the website where you want to enable 2FA account and paste the address and then Click "ADD".
Ex: Altcoinstalks 2FA Guide
Address: LBCUE6MW2GV2I4VI
You can see the "CODE" now in your mobile device and it changes time after time
Now, type the code where you copy the address and "CLICK ENABLE 2FA".
Ex code: 105885
You're good to go. You're 2FA is enabled.
TAKE NOTE:
Don't forget to backup address key because it's very important when you lose your device. Make sure it's well written on the piece of paper or make a backup copy in your USB device or PC.
REASON: You can't get code again from another device if you don't have a back up of your address ( 16 digits) and you lose your mobile device but if you did save a back up and by doing the same steps in the guide with the same address key (16 digits) you use in google authenticator that you backed up then you don't have to worry.
Feel free to ask questions or correct my mistakes If i have mistakes in my guide.
In my case I enable 2FA in my account in einax.com to be an example on how to enable 2FA.
