It's no joke that cryptocurrency exchanges are prime targets for cybercriminals with so much capital on the line. Because of this it is not possible to overstate the value of keeping your personal account as secure as possible. In this respect, Binance is one step ahead, as it wants you to allow two-factor authentication to keep your bitcoins and alt-coins safe.
The famous exchange allows you to allow two-step authentication on your account for making withdrawals as a safeguard against unauthorized entry, while you can sign in, conduct trades, and make deposits on Binance. Although mainland China users have the option of obtaining SMS-based authentication to safely get into their accounts, to stay protected from hacks, the rest of us have to rely on Google Authenticator.
STEP 1: On Your Phone, install Google Authenticator
If it's not already open to you, Google Authenticator is a free app that applies a security layer to any accounts you sync with. You can catch it below for Android.
STEP 2: Enable Google Authenticator on Binance
Go to the Binance website on your desktop, laptop or handheld computer with Google Authenticator enabled on your iPhone or Android, then sign into your Binance account. You will now be led to your user interface, so next to the Google Authenticator section near the lower-right corner, click on the "Enable" tab.
From there, either by clicking on the numbered tabs at the top of the box or the "Next Step" button in the bottom-right corner of the page, follow the instructions. Steps 2 and 3 are practically the same and show your backup key, but phase 2 contains a QR code so you can check whether you are using your Mac or Computer with your mobile.
It's incredibly important that you write down your 16-digit backup key and keep it secure elsewhere, regardless of whether you go for Phase 2 or 3. We suggest making more than one copy. If your phone ever gets lost, damaged or stolen, Binance will need it to verify your account. That said, if you are using a Mac or PC, keep your phone handy, and proceed to the next step.
STEP 3: Add Binance to Google Authenticator
Open the Google Authenticator app on your iPhone or Android smartphone and press either "Begin Setup" (iPhone) or "Begin" (Android). At the bottom of the screen, a prompt will appear telling you to either 'Scan Barcode' or 'Enter a Given Key,' so tap your chosen method to continue.
If you have decided to manually insert the Binance backup key, enter the name and backup key of your preferred account in the fields given. From there, you'll need to pick between "Counter based," which refreshes after tapping every five seconds, or "Time based," which refreshes every 30 seconds automatically. We consider choosing the latter as it gives you more time to sign in or make withdrawals as you turn between Google Authenticator and Binance. Tap either the "Add" (Android) or the search (iOS) button until you're finished, and Binance will be added to Google Authenticator.
If you are using a Mac or PC and you want to search the QR code of your backup key, first by pressing "Grant" or "Allow" on the confirmation prompt that appears, giving Google Authenticator permission to use your phone's camera. Your camera is now free to search your key, so simply point it to the QR code and Google Authenticator will be added to Binance automatically.
STEP 4: Finalize Setup on Binance
With Binance added to your Google Authenticator app, go back to your browser's Binance account to finalize the setup for two-factor authentication. To do so, near the upper-right corner of the screen, click on '4. Enable Google Authentication' and enter your 16-digit backup key, login password, and 6-digit 2FA code from the Google Authenticator app in the fields provided.
From there, once you're done, click on the 'Enable Google Authentication' button in the lower right corner. You can quit the browser now.
STEP 5: Log into Binance with 2FA
Now that Google Authenticator has been set up every time you log into Binance and confirm withdrawals, Binance will now ask you for your 2FA code. It's really simple to use two-factor authentication, though.
With your email and password, log into the Binance app as you normally would. You'll be prompted to enter your Google Authenticator 2FA code from there. So, open the Google Authenticator app and you'll see a list of all the accounts that you've attached to Google Authenticator (that's all you'll see if you've just added Binance). Just pay attention of the six-digit "Binance" code above and then switch it back to the Binance app and enter the code to log in with the field provided.
You'll have to reinstall it to regain access to your Binance account if you ever uninstall the Google Authenticator app or get a new phone. Apart from that, you just need to retrieve the 16-digit backup key you copied in Step 2, then manually re-enter it as described in Step 3 in Google Authenticator. Once finished, you will be able to log in to Binance as you would normally do.
You will be significantly safer from outside threats with Google Authenticator now attached to your Binance account, as no one can get into your account without physical access to your smartphone and the Google Authenticator app it contains. You can now make withdrawals directly from the Binance app even better simply check out the following guide to learn more about that aspect.
