What is 2-Factor Authentication? – Low End Box

What is 2-Factor Authentication?This article was contributed by Dustin B. Cisneros from RackNerd. If you are looking for a new VPS or web hosting service, be sure to check out RackNerd’s latest LowEndBox specials!

In this article, we will be talking about a more generic and broad topic that is important to all of us internet users, whether it be related to LowEndBoxes or otherwise. Inspired by a surge in digital security threats and vulnerabilities on the Internet recently, in this topic we will talk about 2-Factor Authentication, and tell you all about it and why you should use it for your online accounts (such as your e-mail accounts).

What is 2-Factor authentication?

2FA is a form of multi-factor authentication; it makes use of two factors of different types to authenticate a user. The first factor could be a password, while the second factor can differ and include things such as a one-time password that you receive on your mobile phone.

The majority of websites and applications now use 2-Factor authentication. You might already have used 2FA in the form of biometric verification, where only your fingerprint, along with a password, can authenticate your identity.

There are different ways in which 2FA is implemented. The most common way is that you provide your password as the first factor. The website server then verifies the given password with the stored encrypted password – and if it matches, it takes you to the second factor. In the second step, you are sent a one-time password or a PIN to your stored phone number. You would only be able to access your account when you enter that OTP or PIN.

Other second authentication factors can include the use of email, smartphone apps, biometric verification, and even physical devices such as RFID cards and tokens. 

Why is 2-Factor authentication important?

Nowadays, using only a single layer of protection, such as a password, is not secure enough. There are numerous ways in which a password can be stolen or cracked.

With the increase in computing power, brute force attacks are getting more frequent. Moreover, what makes it all worse is the use of weak and short passwords. Passwords such as “password123” are still commonly used, even though they can be easily cracked or even guessed.

The problem with only using a password is that it is difficult to remember a strong password. Therefore, people tend to use easy and memorable passwords. Additionally, passwords are also potentially exposed to threats such as keylogging and data recovery of old storage drives.

Thus, the use of 2-Factor authentication provides a safety net for your online accounts. Even if the attacker has your password, your account will remain secure as long as they don’t have access to the second factor. That is why the second factor is something that only you have access to, such as a mobile phone or an RFID key.

However, devices such as mobile phones and keys can also be stolen; thus, in high-security environments, the use of 3FA (3-Factor Authentication) has started. 3FA can include a password, an OTP, and biometric verification used together.

Alert message box doesn’t display

I have following lines of code for insert record. I want to display an alert message box saying record added successfully. However, record inserted successfully but the message box doesn’t display and opens the main.php file directly. How can I display the message as well as open the main.php

$stmt = $link->prepare("INSERT INTO users (name, address, mobile, 
email) VALUES ('$name', '$address', '$mobile', '$email');
  echo '<script>alert("Record added successfully")</script>';
  header("location: main.php");
 } else{
     echo "No record added. Something wrong.";

Why does the size/extents of a bounding box of a BoxCollider in Unity show the Z element being double what it is?

As you can see from the picture below, I fetch the BoxCollider inside CollisionHandler and Debug.Log() it to the screen.

In this case, I’m logging the size, but the same thing happens with extents. There are 4 logs because I have 4 instances of the object in the scene.

The Z value of the Vector3 is double what it should be, whereas the other values are, for the most part, normal. Also, it seems that each object prints a slightly different value for extents.z. Most stay around 1.3, but one gave me 1.07~.

Additionally, it inverts the order for 2 of the objects. I don’t know why.

None of the objects are scaled and all use the exact same values for their collider.

Screenshot of Unity

I tried drawing a cube with the same size as the BoxCollider’s bounding box, and here’s what I got:

Bounding box drawn with Gizmo.DrawBox from the top

Bounding box drawn with Gizmo.DrawBox from the side

The bounding box gizmo and the box collider, side-by-side

The bounding box gizmo and the box collider, side-by-side from the top

I’m not entirely sure if the misalignment with the Collider in the scene is a sign of a problem or just how Gizmos.DrawCube() works. Here’s the code that does this:

private void OnDrawGizmosSelected() {
    Vector3 origin = + transform.TransformDirection(new 
    Vector3(0f, 0f, 0.675323f + skinWidth));
    // The hardcoded number above is Z extent of the box.
    Vector3 direction = transform.TransformDirection(Vector3.forward) * 2;

    Gizmos.color =;
    Gizmos.DrawRay(origin, direction);
    Gizmos.DrawCube(origin + direction, coll.bounds.size);
    // Where coll is a reference to the BoxCollider, cached in Awake().

Unity version 2019.3.15f1.

For the X value of 2.286476, it rounded to 2.1 in the 3rd log for some reason. And in the first log, it rounded the doubled value of Z to 2.4 rather than 2.6…

macos – Screenshot of an X11 box gets white

I’m facing a little problem while taking a screenshot of an X11 window
(using XQuartz – if there’s something better out there, lemme know).

I tried everything:

  • Entire Screen
  • Window-Only
  • Selection

Even tried recording the screen, same results – the box I need to screenshot (the one on the right) is always white:

enter image description here

(Side note: In the pic above the window is not “focused” (selected), but even with the “focus” on it, nothing change – even tried using the XQuartz setting where it focus the window on mouseover.)

This is how it should be:

enter image description here

Any idea on what setting I might need to change, in order to get my screenshot to work properly?

Oh… Almost forgot, I’m running the last macOS Catalina update (10.15.6)

Thanks in advance.

Edit: Added a pic of how it should be.

magento2 – I want to remove light box and enable magnifier in product image

I tried this

        <var name="magnifier">
            <var name="fullscreenzoom">20</var>  <!-- Zoom for fullscreen (integer)-->
            <var name="top"></var> <!-- Top position of magnifier -->
            <var name="left"></var> <!-- Left position of magnifier -->
            <var name="width"></var> <!-- Width of magnifier block -->
            <var name="height"></var> <!-- Height of magnifier block -->
            <var name="eventType">hover</var> <!-- Action that atcivates zoom (hover/click) -->
            <var name="enabled">true</var> <!-- Turn on/off magnifier (true/false) -->

and this

<var name="gallery">
          <var name="allowfullscreen">false</var> <!-- Turn on/off fullscreen (true/false) -->

gui design – What is the best way to clear text inside a text box?

Usually When using expandable text boxes there isn’t a way to clear them unless having a reset button underneath which won’t work very well when displaying information in a grid.

What do you think is the best way to clear text inside the expandable text box as seen below? A regular text field is displayed where I’d usually put an X so the user can clear the text.enter image description here
