Is Using Default Passwords on Your Yealink Device Safe?

Yealink specializes in video conferencing, voice communications, and collaboration solutions and ranks No.1 in the global market share of SIP phone shipments. Session Initiation Protocol (SIP) phones depend on internet technology to establish multimedia communication, as this ensures that the network is secure and reliable.  Most Yealink phones use a single standard default username and password, and this raises serious security concerns. In this article, we explain the risks associated with using the Yealink default admin password, and how you can create secure complex passwords and safely store them using a single security tool.


Default Passwords

Devices and software often have standard pre-configured passwords which, of course, can be easily known to hackers. These passwords should be changed. Pre-configured credentials are meant to be only suitable for the initial setup or after a factory reset has been made. Though they are practical at this stage, however, they present serious security risks if left unchanged.


Yealink phone default passwords are typically weak and lack sophistication. A common problem in the corporate environment is the local administrator is responsible for setting the password that users are to use, and in such cases, users are prohibited to change it to one that the administrator does not know. The administrator might set a password that’s easy to remember and fail to take into account the need for a more complex and secure password. 


Passwords are meant to control access and ensure security, making use of weak default admin passphrases will run you the risk of being attacked in at least one of the following ways:


VoIP Hacking

Yealink phones depend on the internet to make their connections, and this is referred to as VoIP. Hackers are able to attack VoIP phones to penetrate business phone systems. This kind of hacking allows them to listen in on calls, and steal sensitive information about your business and your customers.



Keyloggers are malicious software that covertly tracks your keystrokes and reports them back to a hacker. Regularly inspect your computer and run a virus scan. Familiarize yourself with each hardware that's connected to your Yealink device.


Brute for attack 

A hacker can systematically try 2.18 trillion passphrases combinations in 22 seconds, and if your password is simple, your account could be compromised. Using a complex password comprised of upper and lowercase letters, numbers, and mixed characters. This unique composition increases the complexity of your password(s), which will significantly reduce the chances of a successful brute force attack.
