Mac Password Generator

Generates strong, unique passwords locally on macOS through a secure terminal workflow. The tool focuses on offline credential creation for security-conscious professionals such as system administrators, developers, and security engineers who rotate credentials regularly. It accepts a desired length and a combination of character sets, and it can exclude characters that are visually confusing. The generation process uses the OS cryptographic RNG, ensuring high entropy without any network activity. Output can be a single password or a batch of passwords, each independently evaluated for compliance with policy settings and common security standards. The approach emphasizes privacy, reproducibility when seeds are provided, and auditable randomness.

Core capabilities include policy-driven input, deterministic seeding, and batch generation. Required inputs are length, inclusion flags for lowercase, uppercase, digits, and symbols, plus an optional exclusion list. Optional/advanced inputs add a seed for reproducible results, a batch count, and custom symbol sets. The tool computes entropy as log2(N) × L, where N is the number of allowed characters and L is the password length. It validates inputs, filters disallowed patterns, and can produce multiple outputs with consistent policy. Outputs are plain strings suitable for copy to clipboard or secure storage.

Use cases span credential rotation for servers, cloud apps, and CI pipelines, onboarding new users, and enforcing enterprise password standards. Outputs are ephemeral and consumed by downstream systems; the tool does not transmit data. Security considerations include offline operation, use of the OS RNG, and memory clearing after use. Unique differentiators include deterministic seeding, explicit control over ambiguous characters, offline operation, and a transparent entropy model that supports auditing and policy compliance.
