इस उपकरण के बारे में
Generate secure random passwords using cryptographic randomness.
कैसे उपयोग करें
Adjust password length using the slider (8-128 characters)—longer is exponentially more secure. Toggle character sets: Uppercase (A-Z), Lowercase (a-z), Numbers (0-9), Symbols (!@#$%^&*). Enable at least 2-3 character types for good entropy. Optional: Toggle 'Avoid Ambiguous' to exclude lookalike characters (0/O, 1/l/I) for manually typed passwords. The tool shows real-time password strength (Weak/Fair/Good/Strong) and entropy bits. Click 'Generate' for a new password, 'Copy' to clipboard. Generate multiple passwords with 'Bulk Generate' (up to 100 at once) for batch account creation or password rotation. Entropy formula: log2(charset_size^length)—a 12-char password with all character types has ~78 bits of entropy (2^78 combinations).
सामान्य उपयोग के मामले
User Account Passwords
Generate 16+ character passwords with all character types for admin accounts or high-privilege users.
API Keys & Secrets
Create 32-64 character random strings for API authentication tokens, webhook secrets, or encryption keys.
Database Credentials
Generate strong passwords for production database root users (16+ chars, store in secrets manager).
Temporary Passwords
Create 8-12 character passwords for password reset flows or initial account setup (users change later).
Wi-Fi Passwords
Generate 16+ character WPA2/WPA3 passwords with symbols (avoid ambiguous chars if users type manually).
SSH Key Passphrases
Create 20+ character passphrases to protect private SSH keys.
Password Manager Master Password
Generate a memorable 20+ character password using dice-ware or custom pattern, then manage all others in 1Password/Bitwarden.
सीमाएं और महत्वपूर्ण नोट्स
This tool generates cryptographically strong passwords but cannot guarantee how you store or use them. NEVER store passwords in plain text—hash with bcrypt/argon2. NEVER reuse passwords across services—use a password manager. NEVER share passwords via email/Slack—use encrypted secrets sharing tools. Generated passwords are random—not memorable; for human-memorized passwords consider passphrases (4-6 random words) which offer better usability with similar entropy. The 'crack time' estimate assumes offline attack with modern GPUs (billions of guesses/sec)—online attacks with rate limiting are much slower. Very long passwords (64+ chars) may hit length limits in some systems (e.g., older UNIX crypt() limited to 72 chars for bcrypt). Symbols (!@#$) may cause issues in some contexts (shells, config files)—test or escape properly. For extreme security (government, military), use hardware security keys (YubiKey) and multi-factor authentication, not just strong passwords.
Technical Details
Edge Cases & Tricky Inputs
- •Some websites restrict special characters — use the character set toggles to exclude them.
- •Generated passwords use crypto.getRandomValues() which is CSPRNG (Cryptographically Secure Pseudo-Random Number Generator).
Performance & Processing
- •Password generation is instant — entropy is calculated and displayed in real-time.
- •Bulk generation of up to 100 passwords at once is supported.
Developer Notes
- •Password strength is measured in bits of entropy: 64+ bits is strong, 80+ bits is very strong.
- •The generator never stores or transmits passwords — generation happens entirely in your browser.
Known Limitations
- •Passphrase mode uses a fixed English word list — non-English passphrases are not supported.
- •No password manager integration — copy the password manually.
