Data theft is increasing and now leads to more security breaches than any other kind of attack.
Many employees face hacking risks every day because their passwords are too easy to guess.
A recent survey found that more than half of employees use the same password on several platforms, which makes them more vulnerable than they realize.
A hacker could access your company’s emails and files, and even those of your customers. They might use this information to create fake invoices or convince people their computer is infected.
Multi-factor authentication is one of the best ways to protect your accounts, data, and business. It works by using a code sent by text message along with something you know, like a password or PIN.
This system is popular with companies that want strong security. It adds another layer of protection, even if hackers get your login details.
What Are the Three Main Methods of MFA?
Multi-factor authentication is a great way to make your business more secure. However, there are different methods available, and some may work better for your needs than others. Don’t assume all MFA options offer the same level of protection.
Multi-factor authentication is a strong way to protect your accounts, data, and business. It works by sending a code by text message along with something you know, like a password or PIN.
SMS-based
The most common type of MFA is SMS-based, which uses text messages to verify users. It’s a quick option for people who don’t have other devices, like smartphones with fingerprint readers, although those can sometimes be unreliable.
With MFA, users provide their mobile number when setting up an account. They receive a text message with a code that must be entered quickly to log in.
On-device Prompt in an App
Multi-factor authentication (MFA) is important for both security and convenience. One method uses an app to send the user’s code instead of SMS, which can be more cost-effective than sending many text messages each day.
Push notifications are now an efficient way to reach users. They work with both mobile and desktop apps, depending on your needs.
Security Key
Authenticator keys are another way to keep your accounts safe, especially if you use several platforms. You need to buy the authenticator when you set up your account, so it can be checked before you log in for the first time.
The MFA security key is about the size of a thumb drive, making it easy to carry. You’ll need it for authentication when logging into systems, so be careful not to lose it.

Most Convenient Form of MFA?
The main difference between these three methods is how convenient they are. Some are easier to use than others, but each has its own pros and cons depending on your needs.
Some users feel that MFA slows them down, especially if they need to learn a new app or keep track of a small security key. Losing the key can also be a problem.

Your online accounting system is likely one of the most sensitive parts of your company. If you’re not careful, it could be hacked and all its data compromised. These attacks can be hard to recover from, but with the right security steps, you can protect your business.
Without a security key, your mobile phone could leave you exposed. If your phone is lost or stolen, both SMS-based and app-based MFA may not protect you since they depend on having your device.

Percentage of attacks blocked:
SMS-based: between 76 – 100%
On-device app prompt: between 90 – 100%
Security key: 100% for all three attack types
