Change user kali linux

how to change username and password in kali linux

I want to change my password and username in kali Linux but I have found out that before changing password I should make sure of two things: 1- I’m using an active grub bootloader 2- my bootloader in not locked. I have no idea how I’m supposed to check this things out. I would appreciate any help either about this or how to change username and password.

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it’s currently written, it’s hard to tell exactly what you’re asking.

What you have found out is irrelevant to changing your username. It seems you dont have the knowledge you need to use Kali — you may want to learn a more user friendly distro like Ubuntu first.

Linux: Reset User Password

I want to change my password and username in kali Linux

Changing password in Kali is not part of the Settings Manager (posted here from my Kali machine)

To Change Password:

Open a terminal window and run:

sudo passwd USERNAME

(where USERNAME is the name of the user whose password you want to change).

Type the new password for the other user.

Restart your system to test.

To Change Username:

Best and safest way in any operating system is to make a new user with new user profile and password. Copy your data into the new profile and when fully tested, delete the user and profile you do not want.

How To Change or Rename Username and User ID In Linux?

The problem is we want to change the already created user name or user id. As we know there is a lot of configuration those rely on the user id like permissions. We will use usermod command to make this change. Keep in mind this changes will effects system wide.

List User Info

Before starting to big changes we will list users detailed info with cat command like below.

$ cat /etc/passwd | grep ismail

• test is our user name for this operation
• 1000 is the current id of our test user.

Change User Name

We will change username with the following command by providing new username. We will provide the -l option with the new username and old username. In this example we will change username ismail into ali .

$ sudo usermod -l ali ismail

• usermod is command we issue to chage
• -l ali is the new username
• ismail is the original username

Change User ID

Another opportunity is changing the user ID. Previously we have listed user information of the ismail . We know that the user id of the ismail is 1000 . We will use -u option and the new user id with the user name. In this example we will change the user id of ismail into 1010

• usermod is command used too
• -u 1010 is new user id provided for the user
• ismail is the user whose id will be changed.

Check It Again

After these steps we need to the if there is a problem or everything is OK. We will list user information again with the cat command like below.

• test2 is new username but home directory stays the same
• 1010 is the users new id

Default passwords in Kali Linux

Kali Linux user password

What is the password Kali Linux LIVE

When booting a LIVE image, login credentials are not required. Running commands with sudo also does not require passwords.

What is the default password in Kali Linux

When installing the system, you will be asked to create a user account – username and password for it. These credentials will later be used to log into the system.

How to change your password in Kali Linux

To change your password, run the command:

enter the old password, and then two times the new password.

How to change password for another user in Kali Linux

To change the password for another user, run a command of the form:

What is the root password in Kali Linux

By default, the root password is not set. To set root password in Kali, run the command:

After that, you can log in as the root user.

What to do if you forgot your Kali Linux password

Default password Kali Linux in VMware and ARM images

In all official images, including VMware and ARM, the standard credentials are:

Password: kali

Vagrant Image Password

Username: vagrant

Password: vagrant

Kali Linux Password in SSH

The SSH password is exactly the same as the password for the user on the system. Those. in standard images, the kali username and password. After installing the system or changing the user password, when connecting via SSH, use the password of your account in the system.

It is recommended to configure key authentication, see “How to enable SSH in Kali Linux. How to connect to Kali Linux via SSH” for details.

Default tool credentials

Some tools shipped with Kali will use their own default credentials (others will generate a new password the first time they are used). The following tools have default passwords:

Beef-xss

Username: beef

Password: beef

Configuration file: /etc/beef-xss/config.yaml

MySQL

To initially configure the program and set the root password, run the command:

mysql_secure_installation

If you have already set the MySQL password in Kali Linux, but forgot it, then in the first terminal, type:

sudo systemctl stop mysql sudo mysqld_safe --skip-grant-tables

mysql -u root mysql FLUSH PRIVILEGES; update user set password=PASSWORD('NEW_PASSWORD') where User='root'; flush privileges; quit

Please note that the NEW_PASSWORD line needs to be replaced with the password that you want to set for MySQL root.

In the first terminal CTRL+c

sudo kill `sudo cat /var/run/mysqld/mysqld.pid`

sudo systemctl start mysql

That’s it, now your MySQL has a new password.

PostgreSQL

User: postgres

Password: postgres

How to change PostgreSQL password

sudo systemctl start postgresql.service sudo -u postgres psql postgres

At the psql prompt, enter the command:

\password postgres Enter new password:

Openvas

Username: admin

To set up the program, run the command:

Metasploit-framework

The Kali’s official documentation says:

Username: postgres

Password: postgres

Configuration File: /usr/share/metasploit-framework/config/database.yml

But when trying to connect from msfconsole with these credentials, an error occurs:

Error while running command db_connect: Failed to connect to the Postgres data service: IMPORTANT: user "postgres" did not authenticate (Peer)

Another error option if you do not specify a password:

Error while running command db_connect: Failed to connect to the Postgres data service: fe_sendauth: no password supplied

To fix it, you can do the following. We start the PostgreSQL service, create a new user with (called “user”) with a password and create a database (called “metasploit”) on behalf of this user:

sudo systemctl start postgresql.service sudo -u postgres createuser user -W sudo -u postgres createdb -O user metasploit

msfconsole db_connect user:user_pass@localhost/metasploit db_status
