Secure Password Generator

Generates cryptographically strong passwords based on user-selected constraints. The tool targets individuals, security teams, developers, and IT administrators who need unique credentials without guesswork. It supports quick generation for account onboarding, password rotation, and automation workflows where unpredictable patterns are required. The output is designed for immediate use in credential managers, secure notes, or security audits. The tool differentiates itself by exposing explicit constraints and a clear strength metric to guide policy decisions. The core logic uses a cryptographic RNG to assemble passwords from user-approved character classes. If the user excludes ambiguous characters, the alphabet shrinks accordingly, increasing readability without weakening security. When requested, the tool can enforce at least one character from every selected class. It also provides an entropy estimate to help determine appropriate length and class mix. The audience includes individuals creating personal accounts, security teams provisioning temporary credentials, and developers integrating generated passwords into automation pipelines. The main differentiator is transparency of constraints and a clear strength metric for policy-compliant generation in onboarding and rotation workflows.
