If you ever get a message from your computer or device stating that you require higher privileges than you are, then you may have encountered “root access.”

Operating systems need to find a way to allow users to use the computer as they wish, without making it difficult for others to access and mess with the whole system. You can have root access to any computer.

Operating systems are similar to Onions

OSes (operating systems) are like onions in that they have layers. However, unlike An onion and operating systems kernels.

Kernel is the OS’s lowest layer. The kernel is the part of an operating system that talks to your computer’s hardware. When your computer loads an operating system, the kernel will be the first to load. Always, the kernel remains in RAM. . Computers will crash when the kernel is not working properly. It is the heart of every operating system.

Operating systems are like onions

The kernel contains various OS components, such as device drivers, file system, Application Programming Interfaces, (APIs) and User Interfaces (UI). The interface connects the user to all the OS components in the background.

The majority of users need only a few OS components. This is why OS systems are granted “privilege” levels.

OS Privileges: The Essentials

Like in real life. Having certain privileges on an operating system allows you to access things other users don’t have. You can restrict your access in many different ways. Access to files is a common restriction. When it comes to certain data, you might only be granted “read” privileges. This means you have the ability to read and open files, but cannot modify or delete them. For that to happen, you would need “write privileges..

Certain types of data might not allow you to have any “read” rights at all. A public computer may not be allowed to allow users to view data only employees are authorized to see.

Computer settings, software installation and other restrictions are also common. Users can have different levels of privileges that prevent them from installing, removing or changing the wallpaper on their computer.

Root access is the most prestigious privilege

To have “root access”, you must be granted the greatest privilege on the computer. There are no files or data that you can’t see. Root users have the ability to modify any part of the operating system.

With the same rights as a root user, any application can run with all the privileges that an administrator has. Root access is vital for fixing most problems and maintaining the computer.

An alternative term for root users is “administrator”, though administrator accounts can sometimes have lower privileges that root accounts, depending on what operating system they’re running and how the things are set up. Most of the time, root privileges and admin privileges can both be used interchangeably.

Linux User Privilege Levels

Linux and other “”Unix-likeEach operating system has a unique approach to root account creation. Linux has at most one root account. This is the account that you create when installing Linux. This root account cannot be used for everyday use by default. Instead, when a regular user wants to access root privileges, they must provide a username/password. The password temporarily raises the privileges necessary to complete the task but then falls back to their normal privilege levels.

Linus Terminal is a text-based interface that allows users to use “sudo” as a command. Any commands following sudo will execute with root privileges. You’ll need to enter a password again.

Windows and macOS Users Privilege Levels

Microsoft Windows maintained a relaxed approach to root privileges over the years. If you needed the same level security as Linux, the primary user account had to be the administrator account.

Windows and macos user privilege levels

Microsoft Windows 8.1 and later versions will require administrator privileges to perform certain actions. To trigger the prompt, you need to enter your administrator password. You may also be granted administrator rights to run specific programs. For instance, the application “torch” can be launched Command Prompt Windows Terminal without administrator privileges. You won’t be asked for a password each time you use the Windows Terminal.

Apple’s macOS, just like Linux, is a Unix-like OS. You will need to elevate your privileges per operation whenever you do anything outside of normal use. You’ll see little lock icons in macOS. These lock icons allow you to unlock system settings using the root password, and lock them once you are done.

Windows and macos user privilege levels

MacOS defaults to being more strict with permissions than Windows. If an app requires data to be accessed on a removable hard drive, macOS will first ask you permission.

Root access on Android phones

Many people, even those who aren’t system administrators, first heard the term “root access” and “rooting” when they were looking at Android phones and tablets. Android is an open source operating system. However, most Android phone makers like Samsung and OnePlus won’t grant root access for their customers. These accounts have special access that prevent them from having low-level, root access to their phone’s hardware. You cannot change your Android phone’s operating system, or make any system modifications that weren’t allowed by its manufacturer.

Root access is possible on many smartphones by using an app. However, some phones require more complex rooting processes that involve a computer and Android Debug Bridge (ADB). Root access can be gained by using any of the many one-click root options or tutorials for rooting Android devices.

Root access on android phones

You can modify almost any part of the device from this point, even removing the provider bloatware or disabling the enabling features that the manufacturer tried to restrict. If you wish to completely replace your Android operating system, rooting the phone is the first step. This can include the latest version of Android, custom ROMs, and even stock Android (like a Google Nexus phone) without the manufacturer-specific interfaces. Rooting and unlocking the bootloader on your phone opens up new firmware options.

Some of the most popular apps are SuperSu and Magisk, These are your responsibility and you should not use them. Spend some time reading Android forum posts to learn how owners of the same model phone have fared when rooting.

iOS Devices for “Jailbreaking”

Although Android phones do not give root access right out of the box they are generally more restrictive than iOS. You can enable third-party apps stores on your Android phone and you can install any app you want, even though it isn’t in the Google Play Store.

“jailbreaking” ios devices

Any app Apple does not approve is out of range on iOS. This practice of “jailbreaking ” is in. Jailbreaking can be done on Android phones in the exact same way as rooting, however exploits are required to break iOS security features.

Root Access and the Dangers

One thing to remember when rooting Android and iPhone smartphones is the possibility of your warranty being voided. This is especially concerning as a wrong rooting/jailbreak can result in your device being permanently unusable. The manufacturer might not be able to repair it, even though you have paid them.

Personal computers are more complicated. It is important not to accidentally grant root access to the wrong applications or users. There’s a possibility that malware could gain root access to your phone or computer. This can cause serious damage and put your files at risk. It is important to use an antivirus program on root devices.

The dangers of root access

Let’s say you have root access to your device and want to install custom ROMs. You may not be able to access certain features on your phone and you might experience poor thermal management or lower battery life. Many of these optimizations won’t work with rooted devices that have custom ROMs. Overclocking is a technique whereby the processor and GPU of rooted devices are overclocked. This can cause damage to the device.

Rooting your device

How do you uninstall root access from your device? If your device is still functional, you will be able to “unroot” the device or “unjailbreak” the device. This includes flashing its OEM ROM. This should be done before you sell or give away the device.

Rooting your phone is a great way to empower and be liberated. However, it comes with many risks and caveats so make sure you weigh the pros and cons.
