The Risks and Benefits of Using the Default Root Password
Are you thinking of using the default root password for your Ubuntu server? There are advantages and disadvantages to using this password, and you need to fully understand them before making your decision.
Risks of Using the Default Root Password
Firstly, the default root password is well known, which makes it an easy target for hackers. They can easily use this password to take control of your server and steal your sensitive information.
Furthermore, leaving the default password unchanged for a long time increases the likelihood of unauthorized access to your server. This can cause system malfunctions, data loss, and other security issues.
Using a weak and easily guessable password puts your server at risk as well. Attackers can easily guess common passwords or use software to crack your password, making it easier for them to gain unauthorized access.
In addition, in the event of a security breach, it would be more difficult to investigate as anyone with access to the default root password could have access to your server.
Lastly, using the default password can also create compliance issues. Regulations such as HIPAA, PCI DSS, and GDPR require secure passwords and the prevention of unauthorized access. Using the default password violates these regulations.
Benefits of Using the Default Root Password
On the other hand, there are benefits to using the default root password, one of which is convenience. It’s easier to remember the default password than creating a unique password.

In addition, if you are using Ubuntu server for development purposes, using the default root password can save time and allow for quicker setup of your server.
