ℹ️ About MySQL Password Generator

MySQL password hashes are the stored authentication values used by MySQL and compatible database servers when a client logs in. This generator creates hashes for legacy MySQL formats and the MySQL 8.0 caching_sha2_password style so administrators can test migrations, compare stored values, and prepare controlled lab examples without connecting to a live database.

The MySQL 8.0 reference manual documents the caching_sha2_password authentication plugin, and the older mysql_native_password plugin used by many MySQL 4.1-5.7 deployments. MySQL 8.4 marks mysql_native_password as disabled by default and removed from newer versions, so use the legacy output only when compatibility requires it.

Supported MySQL password formats:

  • MySQL 8.0+ caching_sha2_password: SHA-256 based authentication with a salt and repeated hashing; strongest option on this page for modern MySQL users.
  • MySQL 4.1+ mysql_native_password: * followed by a 40-character hex digest derived from double SHA-1; widely recognized but now legacy.
  • MySQL 3.23 legacy: 16-character historical hash format; weak and included only for old-system analysis.

Examples and use cases:

  • Generate a MySQL 5.7-style value such as *6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4 for known lab input.
  • Compare old mysql.user.authentication_string values during MySQL 5.7 to 8.0 migration planning.
  • Prepare repeatable authentication fixtures for documentation, local tests, or incident-response notes.
  • Identify whether a copied hash belongs to a modern, legacy, or obsolete MySQL authentication format.

Strength ratings:

  • caching_sha2_password: recommended for current MySQL deployments, but still verify TLS, server policy, account rotation, and MySQL version behavior.
  • mysql_native_password: legacy compatibility only; SHA-1 is fast and not suitable for new password storage designs.
  • MySQL 3.23: insecure; avoid for production and treat any surviving use as a migration priority.

Security limitations: generated hashes are not a substitute for strong account passwords, least-privilege grants, TLS, secret rotation, and audited database access. Avoid pasting real production passwords into a web tool. For application password storage outside MySQL authentication, prefer dedicated password hashing schemes such as Argon2, bcrypt, scrypt, or PBKDF2 rather than MySQL account-hash formats.

API Usage Example:
