Why is My MySQL User Table Missing the Password Field on macOS?

MySQL User Table Password Field Missing - Troubleshooting for MySQL Installation on macOS

When trying to modify the MySQL root password on macOS, you may encounter an error indicating that the 'password' column in the user table does not exist. This can be puzzling as the password field is typically present in MySQL user tables.

Background:

In MySQL version 5.7, a significant change was made to the user table. The original 'password' field was removed and replaced with the 'authentication_string' field to store user passwords. This change aims to enhance security and enable various authentication methods.

Troubleshooting:

To resolve the issue, it's necessary to use the appropriate field name for password modification.

Solution:

1. Access the MySQL console using the command:

   mysql -u root

   (Note: You may need to provide a password if you have previously set one.)

2. Use the following query to update the root user's password:

   mysql> UPDATE user SET authentication_string = PASSWORD('1111') WHERE user = 'root';

3. This query will update the 'authentication_string' field with the hashed password.
4. Exit the MySQL console.

Additional Information:

• Verify that you have selected the correct database (e.g., mysql):

  mysql> USE mysql;

• Check the field structure of the user table:

  mysql> DESCRIBE user;

  This will display the table schema, ensuring that the 'authentication_string' field exists.

• Refer to the official MySQL documentation for more details on password management in MySQL 5.7 and above:
