For additional security, BuyCoins' Two-Factor Authentication requires you to enter an OTP sent to your phone each time you want to:
- Buy Bitcoin
- Sell Bitcoin
- Send Bitcoin to another Wallet
Step 1: Go to the Security & Settings pageTo do this, log in, click on the profile icon on the navigation bar, then select ‘Security & Settings’ from the drop-down menu. From the Security & Settings page, select how you want to receive the OTP that'll be sent to your phone. You have the option of receiving your OTP via SMS or Google Authenticator.
Step 2: Select your preferred Two-Factor Authentication method
To enable Two-Factor Authentication, toggle the switch. There are two methods of receiving OTP. Via SMS and Google Authenticator.
If you'd like to receive the OTP via SMS, click on the SMS button, and click on 'Enable Authenticator'. This sends an OTP to the phone number on your profile. You should receive an OTP a few seconds after you the 'Enter OTP' page pops up. Enter the OTP in the number field and click ‘Submit’.
However, if you do not receive an OTP within minutes of clicking the 'Send' button, click on the 'Call your phone' link. This will give you the option of receiving the OTP via phone call.
Google AuthenticatorYou need the Google Authenticator app on your phone in order to be able to use this method. You can find it on the Android and iOS app stores. To receive the OTP via Google Authenticator, open the app, scan the QR code and click 'Enable Authenticator', then you type in the OTP that appears on the app into the number field and click ‘Submit’.
You can also enable Two-Factor Authentication via Google Authenticator on your phone. However, instead of scanning a QR code, you'll be redirected to the app where you're to receive and then copy the OTP.
Step 3: That's all!You have successfully enabled Two-Factor Authentication for your account. Now you have extra security and can be sure all your BuyCoins transactions are controlled by just you.
