In today’s post, I’m going to explain what is two-factor authentication, how it works and how to set up two-factor authentication.

Before that let’s talk about the importance of the two-factor authentication.

The two-factor authentication option is available in various cryptocurrency exchanges and wallets.

After installing, in the authenticator, tap add new.

You can see two options. Scan a barcode and enter a provided key.

The barcode option is simple. Scan the provided barcode as the image above. Then google-authenticator verifies the barcode or the secure private key you entered and then showing a time-based code.

Next, you need to enter a one-time time-based code that appears in your device.

Before that,

You must write down or securely store the backup code which also provided by this process. Because, this backup code is the only access method when your mobile is unavailable. or even after you reset your mobile or got a new one.
