Account Requirements

Account

Different from MySQL, DDM identifies an account by username, not by 'username'@'host'.

Username

• Usernames are case-insensitive.
• A username can contain 1 to 32 characters and must start with a letter. Only letters, digits, and underscores (_) are allowed.

Password

• A password can include 8 to 32 characters.
• A password must contain at least three of the following character types: uppercase letters, lowercase letters, digits, and special characters ~!@#%^*-_+?
• A password cannot be a weak password. It cannot be overly simple and easily guessed.

Account Locking Rules

• If an account fails to log in to the system for 10 consecutive times, the username and IP address of the account are locked. If a locked account is used to log in to the system for a long time, the system considers that a brute force attack occurs regardless of whether the username and password are correct and continuously updates the lockout duration.
• If the locked account and IP address are not used for more than 180s, they will be automatically unlocked.
  

  Account locking is supported in version 3.0.8.5 or later.
