Passwords are hard to remember, so if you have forgotten the MySQL root password, luckily, there is a way to change it. This post has been written for you, and by the end of this post, you will have successfully changed the password of MySQL.

This blog demonstrates how to reset the root password for MySQL and MariaDB databases installed with the apt package manager on Ubuntu. The procedure for changing the root password differs depending on whether you have MySQL installed and the default systemd configuration that ships with the distribution or packages from other vendors.

Before moving on to the answer, it is assumed that you have the latest version of the MySQL database for Ubuntu. This blog will offer an easy-to-follow guide for changing your MySQL root passwords in Ubuntu. Therefore, without wasting time, let's begin.

#### 1. Check MySQL Version
First, check the version of your MySQL because this post contains the solution of changing the root password on version 8 or higher. If the version of your MySQL is lower than 8, then the answer will be different. Run the following command:
```
mysql --version
```
MySQL Version Output:
```
mysql  Ver 8.0.27-0ubuntu0.20.04.1 for Linux on x86_64 ((Ubuntu))
```
#### 2. Stop MySQL Server
To change the MySQL root password, you first need to shut down the MySQL server, run the following command:
```
sudo systemctl stop mysql.service
```
 Check the status of the MySQL server to verify. Run the following command:
```
sudo systemctl status mysql.service
```
#### 3. Skip Grant Tables & Networking
To start the MySQL server without granting the tables and networking check, set the environment variable MYSQLD_OPTS, which MySQL uses on startup. Run the following command:
```
sudo systemctl set-environment MYSQLD_OPTS="--skip-networking --skip-grant-tables"
```
Alright, the environment variable is a set, and we can log in to the MySQL shell providing no password.
#### 4. Start MySQL Service
After setting the environment variable MYSQLD_OPTS, start the MySQL service. Run the following command:
```
sudo systemctl start mysql.service
```
#### 5. Login To MySQL Shell
At this stage, we can access the MySQL database without a password:
```
sudo mysql -u root
```
#### 6. Reset Root Password
Now, flush the privileges first. Run the following command:
```
sudo mysql -u root
flush privileges;
```
Select the MySQL database. Run the following command:
```
use mysql;
```
