What is a remote access code?

What is a remote access code? A remote access code is a numerical or alphanumeric password or key used to gain access to a system or network remotely. It serves as a security measure to authenticate and authorize individuals or devices attempting to connect to a remote computer, server, or network infrastructure. Remote access codes help ensure that only authorized users can access sensitive information or perform tasks from a distance, thereby protecting the integrity and confidentiality of the system or network.


How does remote access code work?

When a user attempts to connect remotely, they are prompted to provide their remote access code. This code is then verified through an authentication process, which may involve username/password combinations, biometric scans, or token-based authentication. Once authenticated, the user gains access to the system or network, and data is transmitted securely through encryption protocols.


The importance of remote access code

Nowadays, remote control is inseparable from individuals and multinational companies. Many users benefited from it, but it also attracted the coveting of many cyber criminals who began to take advantage of this. They steal confidential information to seek illegal benefits. To protect personal information security, whether it is an enterprise or an individual, they need to establish a network security barrier to prevent malicious access into their systems. In remote control software, this network security barrier is the remote access code.


Regardless of whether it is from the family or the enterprise, the network security barrier of remote access code is needed to protect to reduce the security risks of private and public equipment. The secure remote access code can not only improve the security of remote access but also be the first step to solving the related problems of hacker intrusion in remote access.

How to improve the security of remote access code

After knowing what remote access code means, how can the security of the remote access code be improved? Here are some tips:

  • Extend your remote access code as much as possible. When setting the remote access code, set the code as long as possible to make it more difficult for malicious attackers to crack the code.
  • Use a combination of letter case, numbers, and punctuation to set the remote access code. If you simply use numbers or letters, it will be easy for hackers to crack, resulting in the leakage of your personal information or sensitive data.
  • Avoid using personal information as your remote access code. Regardless of your purpose, do not use birthday, wedding anniversary, and other related personal information as remote access codes. This will only facilitate hackers to invade your private network and cause the loss of personal information or sensitive data.
  • Update your remote access code regularly. Do not use the same remote access code for a long time. This will only give hackers an opportunity. Be sure to develop the habit of regularly changing the remote access code to protect your network security.


The improvement of security is of great significance to a remote access code. This is not only the demand of the majority of users, but also the long-term goal of much remote control software.

The significance of remote access code for remote desktop software

Most remote control software requires a remote access code to achieve remote control, which can be regarded as a remote control password and can be used to identify the user and authorize the user to remotely control another device. In the next part, I’ll show you the significance of a remote access code for remote control software.

  • Used to distinguish different remotely connected devices. For remote control software, there is often more than one device that needs to be connected. Therefore, different remote access codes need to be set to label different connected devices so that the software can distinguish which device requests remote control to achieve accurate remote control to achieve the purpose of accurately granting remote control permissions.
  • For safety. If the remote access code is not used in the remote control process, it is likely to cause the entire network to infiltrate, allowing network hackers to find an opportunity to take advantage of it, posing a serious threat to the user’s personal information and related sensitive data, so the remote access code used by the control software is also for security.
  • Grant the authority to remotely control the device. For remote control software, a remote access code is indispensable. Only through this method can you effectively distinguish whether the person or device requesting the connection has the authority to block suspicious persons and prevent them from executing any unauthorized, further maintaining the safety of connected equipment.


It can be said that it is the security of the remote access code that allows remote control software to penetrate into all walks of life and become more and more influential. So, how does remote control software realize remote control through code? Let me give you an example to illustrate.

AnyViewer: Control another computer via remote access code

AnyViewer stands as one of the most secure remote desktop software options for Windows, iOS, and Android devices. It employs the following robust security measures to uphold the integrity of remote sessions:

  • Encrypted remote connections: AnyViewer prioritizes the security of remote connections by utilizing advanced encryption. It employs a robust 256-bit Elliptic Curve Cryptography (ECC) algorithm to safeguard data transmission.
  • Two-factor authentication: Before granting access, AnyViewer enforces a rigorous two-factor authentication process. This additional layer of security ensures that only authorized individuals can access your remote desktop.
  • Device authentication: AnyViewer offers device authentication to bolster security during breaks or in shared usage scenarios. By implementing a straightforward interface lock, AnyViewer prevents unauthorized modifications to your computer settings, thereby preserving your preferences and data integrity.

Step 1. Download and install AnyViewer on both computers respectively.

Step 3. Go to the “Device” tab. Click the PC that you need to control and click "One-click control" to achieve unattended access with one click. 

Connect to My Devices

✍ Note: If you wish to log in to more devices to the same account, it is recommended to upgrade your AnyViewer account to the Professional or Enterprise Edition. By doing so, you can also unlock additional privileges and benefits.


What is a remote access code? A remote access code is a unique alphanumeric code used to authenticate and establish remote connections between devices, particularly in remote control software. It serves as a security measure to ensure that only authorized users can access and control remote devices.

After reviewing the above content, you likely understand the definition and importance of remote access codes, as well as their significance for remote control software. Enhancing the security of remote access codes is crucial for safeguarding both home and business networks against external security threats. Only within a sufficiently secure network environment can the objective of secure remote control be effectively realized. Therefore, improving the security of remote access codes is paramount and cannot be overlooked.
