Password Generator
Customize and generate strong random passwords
Security Guidelines
• Use at least 12 characters for strong passwords
• Include uppercase, lowercase, numbers, and symbols
• Never reuse passwords across different sites
• Use a password manager to store passwords securely
• Enable two-factor authentication when available

Password Security Tips
Length Matters Most
Longer passwords are exponentially harder to crack
• 8 characters: Cracked in hours
• 12 characters: Cracked in centuries
• 16+ characters: Virtually uncrackable
Randomness is Key
Avoid patterns, sequences, and dictionary words
• Don't use common substitutions (@ for a, 3 for e)
• Avoid keyboard patterns (qwerty, 123456)
• Don't include personal information
Use a Password Manager
Essential tool for modern password security
• Store all passwords securely encrypted
• Generate and auto-fill strong passwords
• Sync across all your devices
• Alert you of compromised passwords
Never Reuse Passwords
One breached account shouldn't compromise others
• Each account gets a unique password
• Use a password manager to track them all
• Change passwords after security breaches
• Regular password audits are essential
Common Password Mistakes to Avoid
- • Using personal names or birthdays
- • Simple number sequences (123456)
- • Common dictionary words
- • Short passwords under 8 characters
- • Writing passwords down physically
- • Sharing passwords via email/text
- • Using the same password everywhere
- • Not enabling 2FA when available
Password Strength Comparison
| Password Type | Example | Strength | Time to Crack* | Recommendation |
|---|---|---|---|---|
| Very Weak | 123456 | Very Weak | Instantly | Never use |
| Weak | password123 | Weak | Minutes | Immediately change |
| Fair | Summer2023! | Fair | Days | Should improve |
| Good | B1ue$ky@2023 | Good | Years | Acceptable |
| Strong | Xq8#2pL$9zK*wN& | Strong | Centuries | Recommended |
*Crack time estimates based on offline attack with 10 billion guesses per second. Real-world times may vary based on attacker resources and password storage methods.
Frequently Asked Questions
Yes, our password generator uses cryptographically secure random number generation:
- Browser-based Crypto: Uses window.crypto.getRandomValues() API
- Local Generation: All passwords generated in your browser, never sent to servers
- True Randomness: Uses system entropy sources for unpredictability
- Open Source: Code is transparent and can be audited
This method is the same used by banks, security companies, and password managers for generating secure random data.
Password strength is determined by several factors:
Our calculator shows password entropy (in bits) which mathematically represents password strength. Higher entropy = stronger password.
You shouldn't try to remember complex passwords! Instead:
A good password manager (like Bitwarden, 1Password, or KeePass) is essential for modern digital security.
Ambiguous characters can cause confusion when:
Common ambiguous characters:
These characters can be hard to distinguish in some fonts or when written down. Avoiding them prevents login issues, especially when you need to manually type the password.
However, if you always use a password manager to auto-fill passwords, this is less of a concern.
Modern security recommendations have changed:
Old Advice (Outdated)
- • Change every 30-90 days
- • Forced periodic changes
- • Leads to weaker passwords
- • People write them down
Current Best Practice
- • Use strong, unique passwords
- • Change only when compromised
- • Regular security audits
- • Enable breach monitoring
The National Institute of Standards and Technology (NIST) now recommends against periodic password changes unless there's evidence of compromise. Instead, focus on using strong, unique passwords and monitoring for breaches.
Always change passwords immediately after a security breach or if you suspect unauthorized access.
