About This Password Generator
This free online password generator creates strong passwords and passphrases directly in your browser.
Nothing is sent to the server during generation, which helps protect privacy and reduces risk.
Key Features
- Secure random generation using browser cryptography (`crypto.getRandomValues`).
- Custom length control with uppercase, lowercase, numbers, and symbols.
- Strict policy options: exclude ambiguous characters, avoid repeats, start with a letter.
- Passphrase mode with configurable word count, separators, casing, digits, and symbols.
- Ready-made presets for WiFi, email, banking, and developer API-style credentials.
- Strength meter with entropy score, crack-time estimate, and policy warnings.
How It Works
In password mode, the tool builds a character pool from your selected options and guarantees required
character coverage. In passphrase mode, it combines random words with optional suffix rules. It then
calculates entropy to estimate password strength and brute-force resistance.
Best Practices
- Use unique passwords for every account.
- Prefer longer passwords (16+ characters) for important accounts.
- Use passphrases or strict presets for banking and admin access.
- Store credentials in a trusted password manager.
- Enable 2FA/MFA wherever possible.
Note: Local password history is optional and stored only in your browser when enabled.
