Password Generator Secure

This password generator creates strong, customizable credentials by letting users specify length and which character sets to include. It targets individuals, security-conscious teams, developers, IT staff, and auditors who need unique credentials that meet policy requirements without reuse. The tool operates entirely client-side, avoiding transmission of inputs or passwords. It supports common authentication standards by producing ASCII passwords of a defined length, suitable for use across many services and platforms.
Cryptographic randomness ensures unpredictability, while simple toggles let you tailor outputs to risk tolerance.
Conceptually, the tool uses a cryptographically secure random number generator to select characters from the chosen sets. It does not contact external services or store inputs, passwords, or generated values. The entropy is approximately length multiplied by log2(N), where N is the size of the pooled character set (for example 26 lowercase + 26 uppercase + 10 digits + 32 symbols = 94). A 16-character password from all sets yields roughly 105–106 bits of entropy, providing strong resistance to guessing and brute-force attacks.
Core features include length control with a safe default range, toggles for lowercase, uppercase, digits, and symbols, an option to exclude ambiguous characters (such as O, 0, I, l), and exact-length output formatting. The tool is suitable for onboarding credentials, account creation workflows, security audits, and test environments. It is designed to be easy to audit and integrate into scripts or pipelines that require deterministic behavior when seeded.
