Dear steemit friends,
I am sure most of you already know about google authenticator apps ? But did you also have all the back up QR codes ?
I have the google authenticator installed in my phone but I realize I didn't keep the back up of the QR codes.
It means if my phone was stolen or if I reinstall the apps during that period , I will have lost the access to my exchange accounts.
What is two-factor authentication (2FA)?
Two-factor authentication (2FA), often referred to as two-step verification, is a security process in which the user provides two authentication factors to verify they are who they say they are.
Do I need this ?
Yes! If you have an account on any crpyotcurrency exchange like bittrex, bifinex, binance.
Although exchanges are not 100% secure , this is the the set up you should do to protect your account..
You can download easily to your mobile either IOS or Android for free.
How to add 2 FA on exchanges ( bittrex, bifinex, binance,kucoin etc)
This process has to be done via setting > Security > Enable Google Authenticator/ 2FA.
Every exchange has different display but you should be able to find on Setting option.
* Once you enable the 2 FA , it will then give you a QR Code and secret key.
* You will need to save the copy of QR code and the key
* This is the only way you can recover if you lost your phone, crash the apps etc
* After saving the QR code and key , you can then proceed to adding on your google authenticator apps
* To add, click on + sign, scan the bar code
* Then you would see the 6 number digits, register to that particular exchange.
If you already have 2FA enable, but didn't have back up like me
You would need to disable the 2 FA
And then enable again
It will give you a new QR code and secret key
Back up somewhere safe
Scan and register again in your phone
