Passwordinator

API

Free API for generating random passwords of varying complexities

Overview

The Passwordinator API provides RESTful endpoints to generate secure random passwords with customizable complexity. Key endpoints include GET /generate, accepting parameters like length (8-128 chars), include_uppercase, include_numbers, include_symbols, and exclude_similar_chars. Responses are JSON-formatted, returning the generated password and metadata (complexity score, character type breakdown). Use cases: integrating into user sign-up flows, password reset tools, security apps, or educational platforms teaching password best practices.
