What is 2FA?

The moment you start researching Bitcoin and blockchain, you will see how important security is. From choosing the right crypto wallet to deciding if you will join a private or a public chain.

 

So What is 2FA, and How Can it Help You?

The crypto community respects and implements proper security at all times, which means you will see 2FA a lot. 2FA stands for two-factor authentication, and this is what most newcomers will use, and remain using for some time.

Typically you will log in to somewhere with your username, which can be your email address and a password. However, you can add an extra layer to that in the form of 2FA. 

Typically two-factor authentication will be a code that is sent to your emails or your mobile phone, but they also come in USB authenticators. 

When you sign up for any exchange, you should immediately add 2FA. Most exchanges will now require you to use 2FA. 

The majority of the population got used to two-factor authentication because many social media platforms offer it as an extra layer of protection. Hackers can gain access to exchanges through the email you have signed up with. 

Two-factor authentication minimizes that considerably.

  • Authy
  • Yubikey

In summary, 2FA is an added layer of protection on your accounts. It can be the difference between getting hacked and staying safe.
