Password Generator
Generate secure, random passwords instantly in your browser.
About the Secure Password Generator for 2026
This password generator uses the browser's built-in Web Crypto API (specifically crypto.getRandomValues) — the same cryptographically secure random source recommended by NIST and used by password managers like Bitwarden and 1Password. Unlike Math.random()-based generators, the output is unpredictable enough for high-value accounts. The generated password never leaves your device, never appears in network logs, and is not persisted in any storage. Following NIST 2025 guidance, the default length is 16 characters with the full character set, giving you well over 128 bits of entropy — strong enough for banking, email, and admin accounts.
What people use it for
- One-off strong passwords for new account sign-ups
- Service-account credentials for CI/CD pipelines
- Per-environment secrets (dev / staging / prod)
- Database root passwords and API keys
