This tool creates strong, random passwords using a combination of character types you select. It uses the Web Crypto API (crypto.getRandomValues()) for cryptographically secure randomness — far stronger than Math.random(). Your generated password is never sent to any server; it exists only in your browser.
Password strength comes from length and character variety. A 16-character password using uppercase, lowercase, numbers, and symbols has over 7 quadrillion possible combinations. Length matters most — a 20-character lowercase-only password is harder to brute-force than an 8-character mixed password.
Use a password manager (such as Bitwarden, 1Password, or KeePass) to store generated passwords. Never reuse passwords across sites. Enable two-factor authentication wherever possible as a second layer of protection beyond your password.
Yes. The generator uses crypto.getRandomValues(), a cryptographically secure random number generator built into all modern browsers. Passwords are generated entirely in your browser and never transmitted anywhere.
Weak (red): easy to crack. Medium (amber): acceptable for low-risk uses. Strong (green): suitable for most accounts. Very Strong (dark green): recommended for financial and critical accounts. Ratings are based on length and character variety.
Yes. A 20+ character password with mixed types is excellent for WPA2/WPA3 Wi-Fi security. Keep it stored in a password manager rather than memorising it.
