Custom Password Generator

The tool generates a password by taking user-defined length and allowed character groups to create a high-entropy credential. It supports uppercase, lowercase, digits, and symbols, with optional exclusions for ambiguous characters and repeated characters. The process is cryptographically secure and operates locally, ensuring inputs are not transmitted. Conceptually, the password is formed by combining a user-defined character pool with a secure random source and applying optional constraints. This provides predictable policy adherence while maximizing resistance to guessing and brute force attacks. The tool benefits security teams, developers, and individuals who must meet stringent password policies without external dependencies. Its differentiators include offline operation, explicit control over repetition and ambiguity, and a transparent entropy calculation that helps users understand strength relative to length and composition. Core features include adjustable length, selectable character sets, optional exclusions, and an entropy estimate. Typical use cases include onboarding new employees, rotating credentials, and generating service accounts with strict password requirements.
