Introduction

Every developer experiences errors while writing code. Errors are not just obstacles; they also guide us on how to improve our code. MySQL Error 1819 is one such common error encountered during MySQL operations.

 In this article, we delve into what causes this error, how to resolve it, and what preventive measures we can take in the future.

What is MySQL Error 1819?

MySQL Error 1819 (HY000): Your password does not satisfy the current policy requirements, is a common issue related to password validation in MySQL. It usually occurs when a password does not meet the standards defined by the active password policy. The syntax of the error message is as follows:

ERROR 1819 (HY000): 

Your password does not satisfy the current policy requirements

For instance, this error can occur during the creation of a new user with a weak password as below:

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'pass';

Understanding MySQL Password Policy

MySQL provides a plugin named validate_password, which is responsible for enforcing password policies. It checks the passwords and ensures they meet certain criteria. The validate_password plugin considers several parameters like length, numeric characters, complexity, etc.

You can check the current password policy with the following command:

SHOW VARIABLES LIKE 'validate_password%';

Resolving MySQL Error 1819

Resolving Error 1819 involves conforming to the active password policy or modifying the policy to suit your needs. Here's how to do it:

Conforming to the Password Policy

The easiest way to resolve this error is by changing the password to meet the current password policy's requirements. If the policy mandates a certain length or complexity, ensure your password conforms to those rules.

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'ComplexP@ssw0rd!';

Modifying the Password Policy

If you need to set a simpler password, you can modify the password policy settings. For instance, to reduce the minimum password length:

SET GLOBAL validate_password.length = 6;

Remember, this should be done judiciously, as it can affect system security.

Preventive Measures

To avoid Error 1819 in the future, adhere to these best practices:

  • Always create passwords that meet or exceed the active policy requirements.
     
  • Regularly review and update your password policy to suit your security needs.
     
  • Educate users about password requirements to minimize these errors.
