Generation
From online accounts to sensitive data protection, our random password generator creates cryptographically secure passwords with customizable length and character sets. Perfect for enhancing security across all your digital assets.
Whether you're securing personal accounts, managing enterprise credentials, or implementing security best practices, generate with confidence using our secure password generator with real-time strength analysis.
How Secure Password Generation Works
Simple Steps:
- 1Select password length: 4-64 characters (16+ recommended for strong security)
- 2Choose character types: uppercase, lowercase, numbers, and symbol options
- 3Configure symbols: no symbols, easy symbols (!@#$%^&*), or all symbols for maximum security
- 4Enable ambiguous character exclusion to avoid confusing l, I, 1, o, 0, O when typing
- 5Click Generate to create a cryptographically secure random password with real-time strength analysis
Pro Tips:
- Use at least 16 characters for strong security - longer is always better
- Enable all character types (uppercase, lowercase, numbers, symbols) for maximum strength
- Use "Easy Symbols" if you need to type passwords manually, "All Symbols" for maximum security
- Enable "Exclude Ambiguous" to avoid confusing characters when typing passwords
- Store passwords in a password manager instead of trying to remember them

4 Password Length & Crack Time Analysis
Password length exponentially increases crack time. Here's how long it would take to crack passwords using modern hardware (assuming 100 billion guesses per second):
| Length | Lowercase Only | Mixed Case + Numbers | All Character Types |
|---|---|---|---|
| 8 chars | 2 seconds | 1 hour | 7 hours |
| 10 chars | 2 minutes | 6 years | 54 years |
| 12 chars | 2 hours | 2,000 years | 34,000 years |
| 16 chars | 5 years | 7 million years | 200 million years |
| 20+ chars | 13,000 years | 2 trillion years | 100+ trillion years |
5 Password Security Best Practices
✅ Do This
- •Use a password manager: Store all passwords in a secure password manager like 1Password, Bitwarden, or KeePass. You only need to remember one strong master password.
- •Generate unique passwords: Create a different password for every account. If one is compromised, others remain secure.
- •Enable 2FA/MFA: Use two-factor or multi-factor authentication wherever possible for an extra security layer.
- •Use 16+ characters: Longer passwords are exponentially more secure. For critical accounts, use 20-32 characters.
- •Include all character types: Mix uppercase, lowercase, numbers, and symbols for maximum security.
❌ Don't Do This
- •Reuse passwords: Never use the same password for multiple accounts. A breach on one site compromises all your accounts.
- •Use personal information: Avoid names, birthdates, addresses, or dictionary words. These are easy for attackers to guess.
- •Write passwords down: Don't keep passwords on sticky notes or in plain text files. Use a password manager instead.
- •Share passwords: Never share passwords via email, text, or messaging apps. If sharing is necessary, use secure methods.
- •Use short passwords: Passwords under 12 characters are vulnerable to brute-force attacks, even with mixed character types.
