Enable 2-Step Verification
2-Step Verification acts as an extra layer of security for your wallet. When logging in you will need both the wallet password plus the one-time password (OTP) generated via an SMS message to your newly linked mobile device, or through Google Authenticator.
If you'd like to use your mobile device and you verified it in the previous step, then simply select Use your mobile phone number. SMS 2-step verification will be enabled after you click this option.
Google Authenticator or Yubikey
If you choose to use Google Authenticator, select Use Google Authenticator or Yubikey.
You'll be presented with some basic instructions, as well as a QR code to scan.
For those on Android devices: Open Google Authenticator on your device, click the 3 dots in the upper right corner and select Add an account, and Scan a barcode.
For those on iOS devices: Open Google Authenticator on your device, click on the + symbol in the upper right, then click Scan barcode.
Scan the QR code with your mobile device. Once this is complete, you'll now see your Wallet ID listed below 6 numbers that change randomly every 30 seconds.
Back in your Blockchain wallet, enter the 6 digits and click Enable 2FA.
