Two-factor authentication has been around since iOS 10. It's a handy option that adds an extra layer of security to your iPhone and makes its almost impenetrable security even stronger. This feature has remained intact in iOS 11 and iOS 12, and thanks to the straightforward nature of iOS, is relatively easy to enable.
If you didn't get the memo, passwords aren't enough protection for your online accounts. Even a long and complex password offers only one line of defense which can falter. Two-factor authentication adds an additional layer, bolsters your defense, and decreases the risk of your account becoming compromised.
As great as the Internet is, it is not without its dangers. Hackers at any time may be breaking into your online accounts and compromising your sensitive information. Last year, hackers broke into Facebook, Gmail, and Twitter and made off with 2 million stolen passwords.
When it comes to cybersecurity, one layer isn't enough. A complex password (or one created with a password manager) does a good job of protecting your data, but it can still be cracked. Two-factor authentication strengthens this by adding a second layer of security, giving you even more protection against online threats.
Two-factor authentication (also known as 2FA) adds a necessary additional layer of security to your username and password in many important apps. On Instagram, 2FA requires you to confirm it's you attempting to log in, with a special code sent to you via text message. Enter the code and you're in ... but what happens when you need to log in and don't have access to your phone?
When it comes to digital security, one of the best ways to protect yourself is to use two-factor authentication. Most apps these days support it, including Facebook, a site where the more privacy you can muster, the better. However, of the two 2FA options available for Facebook, only one should be used as the other will share your phone number with the world, a huge privacy concern.
There are two different methods of Authentication in OnTime, and each method has two different ways that the authentication can take place. In this installment from Axosoft's own series of video tutorials on the OnTime Project Management Suite you'll learn about these forms of authentication.
The peaceful, pastel and doily-filled world of Pinterest is my oasis. My account conveys who I want to be and what I want to accomplish, so the idea of someone hacking it and ruining my favorite escape for me is heartbreaking. Fortunately, Pinterest has updated its security, implementing three new features to hack-proof your account.
With so much money on the line, it's no surprise that cryptocurrency exchanges are prime targets for cybercriminals. Because of this, the importance of keeping your personal account as secure as possible cannot be overstated. Binance is one step ahead in this regard, as it requires you to enable two-factor authentication to keep your bitcoins and alt-coins safe.

Need a little help figuring out how to factor the difference of two square? Learn how with this free tripartite video math lesson. From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just study for that next big test).
In this video, the instructor shows how to factor trinomials. An equation is a trinomial if it has three terms. If you factor a trinomial, you are left with two binomials which are the factors of the original trinomial. Multiplying them would result in the original trinomial. Now factor the last numerical term such that the sum or difference of those factors gives you the numerical coefficient of the middle term. Now split the middle term according to the factors obtained in the previous term...
Since starting as a simple messenger with self-destructing pictures, Snapchat has grown into a full-fledged social media platform. As features were added, new permissions were requested, and we're all probably guilty of just tapping "OK" to try out the latest and greatest. But at some point, it's a good idea to review your settings to see what personal data you're putting out there for all to see.
One major problem in previous iOS versions is that there was no way to keep messages in sync between an iPad, iPhone, iPod touch, and Mac. If you deleted a message in the Mac app, it would not be deleted on your iPhone, and vice versa. Apple finally fixed this issue in iOS 11.4 by storing all of the messages in iCloud, not on individual devices.
The photo-centric Instagram app is a great way to share "evergreen" pictures and videos when compared to Snapchat and Facebook's new Messenger Day feature. But like all social media, keeping the account secure is an essential aspect, as it restricts unwanted viewers from seeing your content and can prevent unauthorized users from accessing your account. Instagram has several methods for locking down the account including a new two-factor authentication (2FA) mechanism.
Lawrence Perez, from Saddleback College, and his assistant Charlie, give this beginning-algebra two-part lesson on factoring with the ABC method. Solve those darn quadratic equations!
Two-factor authentication (2FA) is a great way to add another layer of security to sensitive third-party apps and websites like Venmo. However, before iOS 12, to log into a particular 2FA-secured app or site on your iPhone, you'd have to memorize or copy the SMS code from Messages, then jump back in a timely manner to log in. Apple's latest iOS version streamlines this process.
In this video the instructor shows how to factor a general quadratic polynomial. Here the first step is to identify the coefficient of the squared term. Write the reciprocal of the numerical coefficient of the squared term out side and write two separate parenthesis which are going to contain the binomials which are the factors of the original equation. The first term of both the binomials is the first term numerical coefficient times the unknown variable. Now multiply the first term numerica...
In this video the instructor shows how to solve quadratic equations by factoring. You can solve a quadratic equation by factoring them. To do this first write the equation in the standard from which is a*x*x + b*x + c = 0. Now factor the equation into two smaller equations of single degree. Now you can apply the zero-factor property to solve the equation in this from. The zero-factor property states that for a real values a and b, if a multiplied by b is equal to zero then value of a must be ...
In the video, the process of factoring trinomials is described. A trinomial that cannot be easily factored in its original form is shown. It is simplified by pulling out the greatest common factor. After that, a trinomial that is easier to factor is shown. Next, the simplified trinomial is broken up into four terms so that factoring by grouping can be done. Once again, a common factor from each pair is taken so that two binomials are created. Once the greatest common factor is added back with...

If you've ever received an email from a sketchy address purporting to be Uber, asking you to sign in with your credentials, you might be a phishing target. Hackers use a fake login page from real-looking domains to trick you into giving up your account information, and while it's been an issue in the past, Uber is making it more difficult on cyber thieves with the addition of two-step verification.
In this video the instructor shows how to factor a polynomial. A polynomial having three terms is called as trinomial. Now if you factor it you will obtain two binomials whose product will be the original polynomial. Before factoring a polynomial you need to find out if the polynomial has a GCF. Look out for the common variables in all the three terms and pull them out which is the GCF of the polynomial. This simplifies the original equation to a polynomial which is of lower degree. Now facto...
In this video the instructor shows how to factor the difference of squares using a formula. The formula to find the difference of squares can only be applied if you have two perfect squares. The formula is (a * a - b * b) = (a - b) * (a + b). That is the difference of squares of two numbers is the product of sum of two numbers and difference of two numbers. So when you need to find the difference of squares of two numbers substitute the values in the above formula to directly solve for the fa...

This lesson describes the method to find the factors of a trinomial, which consists of three terms, by grouping. First of all, factor out the greatest common factor (GCF), and write the reduced trinomial in parentheses. Let the terms of the trinomial be written in order of exponent of the variable. For example, 3(3X2+2X-8) trinomial is written in the order of variable, with 3(GCF) factored out. Now identify the coefficient of the first and last terms, for example in this case, it is 3 and 8. ...
VNC stands for Virtual Network Computing. It is remote control software which allows you to view and fully interact with one computer desktop (the "VNC server") using a simple program (the "VNC viewer") on another computer desktop anywhere on the Internet. The two computers don't even have to be the same type, so for example you can use VNC to view a Windows Vista desktop at the office on a Linux or Mac computer at home. For ultimate simplicity, there is even a Java viewer, so that any deskto...
