In terms of security, Linux is definitely one of the tightest. The password system is one of the most important parts. Without the password, you\u2019re not able to access a secure system and do anything. If you allow system access without a password, it is not secure. No password, no nothing, in terms of security. However, you may also need to change your password at any point. Let\u2019s have a look at changing the password of your system.<\/p>\n
This is the password that you have to enter when you\u2019re logging into your account. This password isn\u2019t the \u201croot\u201d password. Let\u2019s fire up a terminal and run the following command \u2013<\/p>\n
<\/p>\n
This will prompt you to enter your current password. Then, you have to type your new password 2 times.<\/p>\n
The \u201croot\u201d is the ultimate user account for any Linux system that offers the most control over the system, even allowing access to sensitive system files and other files. For changing the \u201croot\u201d password, run the following command \u2013<\/p>\n
# OR<\/p>\n
<\/p>\n
Then, restart your system.<\/p>\n
In cases, you may not be able to access to your system because you forgot the \u201croot\u201d password. It\u2019s also possible to change the password without having access to the system. Restart your system.<\/p>\n
<\/p>\n
Keep holding \u201cShift\u201d to access the GRUB menu.<\/p>\n
<\/p>\n
Press \u201cE\u201d for editing the startup command.<\/p>\n
<\/p>\n
Get to the line \u201clinux \/boot\u201d.<\/p>\n
<\/p>\n
At the end of \u201cro\u201d, type the following text \u2013<\/p>\n
<\/p>\n
Press \u201cCtrl + X\u201d to boot with the modified startup command. Run the following commands \u2013<\/p>\n
mount -o remount,rw \/
\npasswd<\/p>\n
<\/p>\n
Enter your new password. After password changing is successful, run the following command for restarting your system \u2013<\/p>\n
<\/p>\n
Voila! Your password is changed successfully!<\/p>\n
