Password Generation

The /password endpoint generates one or more passwords using cryptographically secure randomness (crypto.randomInt). Supports two modes: random (character-based) and passphrase (word-based). Each response includes the generated passwords along with their strength rating and entropy score.

Use Cases

Generate secure passwords for users during account creation, produce passphrases for easier memorization, test password strength UI, or seed test fixtures with realistic credentials.

Try itget/v6/password
curl -X GET \  "https://api.moxon.dev/v6/password"

Error Handling

  • 400Type must be "random" or "passphrase"The type parameter is not a supported value
  • 400Length must be between 8 and 128The length parameter is out of range for random mode
  • 400At least one character set must be enabledAll character sets are disabled or exclude removed all characters
  • 400Count must be between 1 and 20The count parameter is out of the allowed range
