Create a new user with password in MySQL 8?

You need to use CREATE command to create a new user with password in MySQL 8. Let us check the version

mysql> select version();
+-----------+
| version() |
+-----------+
| 8.0.12    |
+-----------+
1 row in set (0.14 sec)

The syntax is as follows to create a new user with password

CREATE USER 'yourUserName'@'localhost' IDENTIFIED BY 'yourPassword';

The following is the syntax to grant all privileges to the created user

GRANT ALL ON *.* TO 'yourUserName'@'localhost';

Now flush the privileges using flush command

flush privileges;

Let us create a new user with the help of the above syntax. The query is as follows

mysql> use MySQL;
Database changed
mysql> CREATE USER 'James'@'localhost' IDENTIFIED BY 'James123456';
Query OK, 0 rows affected (0.21 sec)

The following is the query to grant all privileges to the newly created user

mysql> GRANT ALL ON *.* TO 'James'@'localhost';
Query OK, 0 rows affected (0.18 sec)

Let us check the user has been created or not

mysql> select user from MySQL.user;

The following is the output displaying the new user we created above

+------------------+
| user             |
+------------------+
| Bob              |
| Manish           |
| User2            |
| mysql.infoschema |
| mysql.session    |
| mysql.sys        |
| root             |
| @UserName@       |
| Adam Smith       |
| James            |
| John             |
| John Doe         |
| User1            |
| am               |
| hbstudent        |
| mysql.infoschema |
| mysql.session    |
+------------------+
17 rows in set (0.00 sec)

Look at the sample output, the user James has been created successfully. Now flush the privileges using a flush command. The query is as follows

mysql> flush privileges;
Query OK, 0 rows affected (0.04 sec)
