The risk of password attacks has increased in the last two decades. Brute-force attacks, i.e. guessing the password using automated bots to find the right combination of the password, are no longer challenging. It’s easier if you use the same combination of passwords for all accounts. According to Yourcybertips, a password alone doesn’t guarantee maximum protection.
You need additional layers of security, such as two-factor authentication, to maximize your device’s safety. As the name suggests, two-factor or multi-factor authentication is an additional step required to get access to your social, business, bank, and other accounts. Once you have typed the right password, you will be prompted to share an OTP (code sent on your email or SMS) to complete the verification. It only takes a few seconds, but this extra step makes it near impossible for an attacker to access your accounts.
Why Do You Need Two-Factor Authentication?
Do you know more than 80% of data breaches can be prevented if you implement two-factor authentication? You may have the habit of changing your password every few weeks or using a strong set of passwords consisting of letters, digits, and special characters. However, a simple mistake and someone will hack your device, escalate their privilege, and exploit your system. Unfortunately, even the big giants are not immune to brute-force attacks.
Two-factor authentication works as dual locks that offer added protection to your accounts. If someone manages to guess your password or conducts a brute-force attack, you can rest easy knowing that they won’t be able to bypass the additional layer of security. This security login is essential to protect your device against phishing attacks. Someone trying to trick you into leaking your personal and sensitive data can’t do that if you have two-factor authentication enabled.
Implementing Two-Factor Authentication: The Most Popular Methods
Although two-factor authentication has become a common security practice for internet users, some sites do not have an option for this additional layer of security. However, with the growing number of cybercrimes occurring at an exponential rate, most businesses have implemented new security protocols to maximize their users’ security. Below we’ve listed the most common types of two-factor authentication for your accounts.
Text Message
The easiest and most commonly used two-factor authentication service is the passcode sent through SMS or email. It’s a one-time password that remains active for a short while and becomes invalid automatically. This passcode is a 4-6 digit code sent to the registered mobile number or email.
Although it’s a secure way of enabling two-factor authentication for your social and other confidential accounts, text messages are not encrypted. This may result in an imposter getting access to this code. Besides that, if your phone gets stolen, the attacker might request the two-factor code on your device and get quick access to all your accounts. While it’s comparatively less secure than other options, having two-factor authentication through text message is much better than not having it at all.
Authenticator App
An authenticator app is a convenient and safest way to implement a two-factor code. These apps do not require an internet connection. You can use authenticator apps to ensure maximum security for your two-factor codes. With these apps, you don’t have to worry about someone getting access to these security codes. It’s transferred in encrypted mode, meaning no one can use it except you.
Security Keys
The safest and most reliable method for two-factor authentication is a security key. These do not have login credentials or any data that can be stolen. These are physical security devices available in various shapes and sizes. Usually, large corporations that have restricted areas allocate security keys to each employee that’s allowed to enter specific areas. These keys are to be held close to the barcode for scanning.
The gates to the room open automatically as you scan the security key. There’s no risk of phishing attacks with security keys, as these are supported by only reputable sites. Plus, no one can get access to your account or the restricted space if they guess the password correctly. They will need security keys to complete the login process.
Enable Two-factor Authentication for Your System
Most apps and websites offer two-factor authentication, but it may or may not be activated by default. You can find it in the security options. Once activated, you can change the configuration so that you are asked to enter the code only when you are logging into your account from another device.
