What Is Duo Security

Security is among the most critical concerns for internet users these days. Unfortunately, many companies and websites just let the issue slide and don’t go the extra mile to ensure their customers’ safety when signing up or browsing around. One of these is Duo Security, a system that offers additional protection to its users. Below we delve into duo security and its uses.

What Is Duo Security?

Duo Security is a two-factor authentication system that provides an extra layer of security for your online accounts. It works by requiring you to provide two pieces of information – usually a password and a verification code – before you can log in. Duo Security is considered one of the most secure methods of logging in to your accounts and is used by many important websites, including Facebook, Airbnb, WordPress.com, and Dropbox.

How Does It Work?

Duo Security is a system that usually offers two ways of verifying your identity; you can either use an automated voice call or send a verification code to your phone via SMS. If you choose the former, you’ll get a message on your phone and need to press the number in the letter to verify yourself. If you choose the latter, the system will ask you to enter the code you receive on your phone. Once you’ve successfully entered both pieces of information, your account is verified.

It sends an automated voice call after entering your password into the login page. You hit # or call, then follow their robotic voice prompts to provide the required information.

It sends a verification code via SMS after entering your password into the login page. When prompted, you will need to input the code it sent you (for security reasons, this usually expires within 5-10 minutes).

How to Set Duo Security Up

Setting up Duo is pretty simple and straightforward: go to the official website and log in with your username and password (for some services, like Facebook, you will first need to create a user account before you can use Duo).

After you enter the duo security login page, it will usually ask you to sign up for Duo (if not, you can click on the menu icon on the top-left corner of the screen and choose ‘Manage accounts’). Confirm your account by entering your phone number. A verification code might be sent to you via SMS; input the code and press ‘Submit.’ You’ll then need to create a password or use an existing one to activate your Duo account.

After signing up, you will choose which services you wish to enable for Duo Security. Note that not all websites support two-factor authentication (for instance, Facebook still doesn’t provide this service to its users), but the list should constantly grow as time goes by.

You’ll be provided with a Duo Security key as you set up Duo. This is your unique identifier (there are different types of keys), which you enter into the login page of each website where you activate the Duo service. You can view all of your registered websites by clicking on the menu icon on the top-left corner again and choosing ‘Manage accounts.’

Is Duo Security Safe?

As Duo Security is a two-factor authentication system, it’s generally considered a very safe and reliable option for protecting your online accounts. It uses some of the most advanced encryption methods to encrypt your data, so you can rest assured that no one will ever get access to any of your sensitive information (such as usernames and passwords).

Despite all of this, there’s still a chance that your account could be hacked into. If you choose to use SMS verification (which we strongly recommend against) or if someone manages to get hold of your phone number, this would open up an opportunity for them to compromise the security on your account (although it would still be complicated).

You should only use the automated voice call verification method to prevent this from happening. These are usually free of charge anyway, so there’s no reason why you shouldn’t use them – they’re just as safe and secure as SMS verification.

Benefits of Duo Security

Below are a few benefits of using Duo Security:

Enhanced Security

It provides an extra layer of protection for your accounts, making it harder for cybercriminals to get into your data. It is the same system used by many big companies and websites, including Facebook, Airbnb, Dropbox, and WordPress, so you know it’s one of the most secure systems available.

Since many people use the same password for all their accounts, sometimes large companies get hacked, and this causes many people to be exposed because of one company’s mistake. Duo Security prevents this by requiring you to prove your identity before allowing access to your account.

It keeps hackers at bay since it stops bots, man-in-the-middle attacks, and pharming.

Speed Enhancer

Duo Security is known to be very quick, with verification codes sent out almost immediately after you request them (usually in less than 30 seconds). This means that the time it takes for you to log in might be reduced.

It can also provide an emergency code, which gives you access to your account even if you don’t have access to your devices. It can be programmed to send out a code that will last for 30 seconds and give you enough time to log in and either reset the password or find the device it’s connected to.


Despite its enhanced security features and services, Duo Security is quite affordable and well worth the money. The basic level of service that you get from Duo Security allows you to protect up to five accounts for a monthly fee, which is a small price to pay in exchange for the protection it offers.


It can be used on both desktop computers and mobile devices, which means you can access your accounts from any device; it also works on all browsers. Furthermore, you don’t need to download anything for it to work (although there is a Duo app if you end up using the system often). The Duo app is available for both Android and iOS.

Its SMS or phone call approach means that you can use it on any phone, including those without internet access.

Fast and Easy to Setup

You can add or remove an account whenever you want or change the devices you’re using – open the Duo Security app on your phone and follow the instructions on the screen. It is free to use, so there’s no reason not to sign up for it if you’re interested.

The process of setting up Duo Security is rapid and straightforward and shouldn’t take more than a minute. You can add or remove an account whenever you want or change the devices you’re using – open the Duo Security app on your phone and follow the instructions on the screen.

Duo Security is a great way to protect your accounts against unauthorized access, but you will need to remember your password. Don’t let it be the first thing you forget daily, or you’ll have no other option but to reset all of your passwords. You can do this by logging in to the website where you activated Duo Security, so keep this key saved somewhere safe.
