There are several types of two factor authorization that protect your accounts. Adding some of these is an imperative step to maintain account security and privacy. By adding an additional layer to login processes, 2fa locks down access to important accounts. As a tech enthusiast, prevent stolen passwords, identity theft, and fraud by adding another access barrier to anyone who might have your basic login credentials. Read on to discover the best two factor authorization types to protect your accounts.
Code SMS/Email Authentication
Code SMS messages or emails are the most basic type of 2fa. Setting up is simple, just tell the service you’re using your email or phone number, and that you want to use it for 2fa. With a phone number or email added, you’ll now need to provide the codes texted or emailed to you besides your username and password. By providing something you know (your normal login credentials) and combining it with something you have (your phone), these services create two factors of identification and security. Since hackers can often spoof phone numbers and send email scams, text-based 2fa tends to be the most vulnerable type. However, it is still significantly more secure than not having 2fa at all. Surely, code SMS and email verification provide the simplest method of significantly increasing account security.
Authentication Apps
Authentication apps generate 2fa codes within the device they’re installed on. Since emails and text messages can be intercepted, keeping codes internally on a device provides additional security. There are several authentication apps out there, many from the biggest players in tech and security industries. They can also integrate with various platforms, allowing you to authenticate logins without switching apps. Authentication apps work by internally generating six digit codes every thirty seconds. This way, the codes are less likely to be recycled and reused. However, losing the device you have the apps installed on often leads to account lockouts. Absolutely, authentication apps offer increased security and integration capabilities.
U2F Authenticator Keys
U2F -based physical authenticator keys provide a solid, tangible, reliable tool for storing authentication keys. They work simply, just plug the key in and register it for an applicable service. Then, connect it your login device, and a token option will appear. Click on it, and you’re logged in. Some keys include fingerprint scans or PINs for added security. Under the hood, two cryptohgraphic keys are created when registering the key, one public and one private. The public key is stored server side, while the private key is stored within the object. This private key encrypts your login information, and uses the public key to decrypt. This way, if someone tries to login with the wrong public key, the encryption produces only gibberish. Of course, you can also use authentication sites to boost security levels as well. Certainly, U2F authentication keys are physical objects that maximize account security in a simple, easy to use package.
Time-Based One Time Password
Time-based one time password 2fa locally generates a key on a device someone is trying to access. Typically, the key is a QR code the user scans with their mobile device, which generates a series of digits. These digits are then used to gain access to the website or application. The codes generated expire after a short time, and new ones get generated when new login attempts are made. Since this 2fa type generates QR codes, they can be used across multiple devices, increasing flexibility. Additionally, local data storage ensures you’ll be able to access your codes, even without a cellular or internet connection. Definitely, time-based OTP 2fa provides flexible, wide access to your information while securing accounts.
Push Notification Authenticators
Push notification authenticators offer increased control over your account security. Once registered, you’ll receive push notifications on your mobile device whenever login attempts are made. If they’re suspicious, many platforms have options to report potential malicious activity in addition to the standard “deny” button. Moreover, when push notifications replace passwords, the risk of phishing, man-in-the-middle, and brute force attacks is severely mitigated. Additionally, they eliminate the need for less secure password habits such as writing them down and repeating passwords. Definitely, push notification authenticators offer simple methods of increasing account security control.
There is a myriad of two factor authorization types that protect your accounts. For example, SMS and email-based codes provide a simple method of significantly increasing account security on the software market. Authenticator apps offer increased security compared to simple codes, and various efficiency increasing integration capabilities. Physical U2F keys maximize account security in a simple manner. Time based one time passwords often provide flexible, wide informational access while protecting your accounts. Finally, push notification authenticators provide the most simple method of increasing security and account control. When wondering about the best types of two factor authorization to protect your accounts, consider the types described above.
