What is Multi-Factor Authentication (MFA)?
Multi-Factor Authentication (MFA) is a type of security procedure that requires more than one method to verify your identity. For example, instead of simply entering a password or PIN to log in, you might be asked to enter a code generated by an app on your phone. This makes it much harder for someone without access to both your computer and phone (for example) to gain unauthorized access.
What is it exactly?
It is a security measure that requires two or more different types of identification (something you know, something you have, and something you are).
Additionally, it's an added layer of protection to your account, especially if you use the same password across multiple sites. This can be helpful for stopping hackers from accessing your personal information because they'll need more than just your username and password to access sensitive data.
For example, if you have MFA enabled on your account, you'll need to enter a code from your phone when logging in. This means that even if someone has your username and password, it won't matter because they won't be able to access your account without physical access to your device.
Types of MFA
MFA can be used in several ways. One of the most common types of MFA is software authentication, which involves using a One-Time Password (OTP) app such as Google Authenticator. The app generates codes at regular intervals, and when you log into your account on a new device, it sends you an OTP for that session.
Another form of multi-factor authentication is hardware-based: when you want to log in, you insert a USB or NFC device into the computer as proof that it's really you who wants access.
There are more forms out there—and some are more secure than others. We consider SMS authentication to be the most vulnerable due to SIM cards and hardware authentication being the safest.
Why use MFA?
Multifactor authentication (MFA) is a strong second layer of security that adds an extra layer of protection to your account. While passwords can be hacked or guessed, MFA helps prevent unauthorized access by requiring something extra only you have.
The most common reasons for using MFA are:
To protect against:
1. Post-data breach damages
2. Phishing attacks
3. To prevent unauthorized access to your accounts
Does Noxity staff use MFA?
You're right to be concerned about the security of your data. We use MFA on everything here at Noxity, and we recommend that you do so as well.
We use a combination of authentication methods to keep our accounts safe and secure. For example, we might log into an account using two-factor authentication (2FA) with an app like Google Authenticator or Authy on our smartphones or use hardware authentication. Or perhaps we'll call in a code via text message when signing into one account but enter a PIN code when logging into another. We can't reveal it exactly :) - You can rest assured, however, that your data is safe with us.
MFA vs 2FA
2FA is one of many types of MFA. It's a method that requires the user to provide two or more pieces of evidence to verify their identity. For example, you might use an app such as Google Authenticator or Authy to get a code for your account when you log in, then type that code into the password field at the same time as you enter your password. 2FA is just one way to achieve multi-factor authentication; it's not necessarily better than other options like biometrics or hardware keys (which may also be considered forms of MFA).
When choosing which method works best for you, consider what kind of access needs protecting—it could be sensitive information stored on your device(s), data stored elsewhere in the cloud (such as email), physical assets like laptops and cell phones, access into private networks at work/home—and how often each type changes hands between owners (for example: when an employee leaves). Then weigh these factors against convenience vs cost: If someone steals my phone while I'm away from home but doesn't have my laptop backup keychain attached there too then they won't be able to get through all five layers just yet!
In conclusion, Multi-Factor Authentication is a critical tool in today’s cybersecurity landscape. It can help make your organization more secure by adding another layer of security to a user’s login process or other critical systems.
