What is two factor authentication (2FA)?
Two factor authentication (2FA) is an extra layer of security used to further protect your account by making sure it’s really you trying to access your account. First you enter your username and password. Then, instead of accessing the account instantly, you are prompted to enter another information. This additional information check can be done in many different ways.
Two-factor authentication methods currently used
You have multiple options depending on the service you use. Below you can see the most commonly used methods:
1. SMS Message : You will receive a four to six digit code that you must enter to access your account via message.
2. Authentication Application: You use authenticator applications that manage your security codes for you.
3. Hardware Security Key : You insert a physical hardware key into your computer that authenticates you.
Advantages of two-factor authentication
Two-factor authentication is a great way to increase the security of your online accounts. Here are some of its biggest advantages:
1. An easy-to-implement security protocol
Two-factor authentication is already installed in most services. Often all you need to do is turn on verification from the application or program settings. Once enabled, it will become a routine part of the login process for you and your team.
2. Free
When it comes to security, it is a free solution to your problems. If you upgrade to the hardware authentication level, you’ll have to pay a fee for the device, but other than that, there’s usually no charge.
3. Protects your sensitive accounts
Finally, it is the simplest way to protect your accounts. It’s not perfect, but it’s a big step forward in helping you keep your information safe from hackers and prying eyes.
Who should use two-factor authentication?
Anyone wishing to improve their level of security on their online accounts should enable two-factor authentication.
This process takes a few minutes at most, helping to prevent your accounts from being hacked and your identity compromised. You can spare a few moments for advanced security measures, right?
