Weak Passwords Are a Top Attack Vector
Despite years of security awareness campaigns, password hygiene remains the single biggest gap in most organizations' defenses — and attackers know it.
According to the 2017 Verizon Data Breach Investigations Report (DBIR), 81% of hacking-related breaches exploit weak or stolen passwords. Using a unique, cryptographically random password for every account protects you against credential stuffing attacks.
Brute-Force Attacks Are Faster Than Ever
Modern GPU clusters can test billions of password combinations per second. An 8-character lowercase password can be cracked in under a minute.
Reused Passwords Multiply Your Risk
One breached site means every account sharing that password is compromised. Unique passwords per account contain the blast radius to a single service.
- Entropy matters: length and character variety are both critical
- crypto.getRandomValues() is a cryptographically secure random generator — unlike Math.random()
- Generated passwords never touch any server — 100% browser-side

Generate a Secure Password in Seconds
No account required. Every password is generated locally in your browser.
Set Your Requirements
Choose the length (8-128 characters) and toggle the character sets you need: uppercase, lowercase, numbers, symbols.
Generate Instantly
Click Generate. Your password is created using crypto.getRandomValues() — a cryptographically secure random number generator built into your browser.
Copy and Store Safely
Copy your password and store it in a password manager like Bitwarden or 1Password. Never reuse passwords across accounts.
Who Needs Strong Passwords
Every account benefits from a unique, cryptographically random password — not just the sensitive ones.
SaaS Accounts
Cloud tools, CRMs, and project management software hold sensitive business data and deserve top-tier credentials.
Company IT Policies
Security teams can generate compliant passwords that meet length and complexity requirements for corporate systems.
Developer Secrets
API keys, database passwords, and service tokens should be long, random, and never reused across environments.
Personal Accounts
Email, banking, and social accounts are high-value targets. A unique generated password for each makes credential stuffing useless.
Frequently Asked Questions
Are the passwords generated securely?
Yes. All passwords are generated using crypto.getRandomValues(), the Web Cryptography API built into every modern browser. This produces cryptographically secure random values — far stronger than Math.random(). Nothing is sent to any server.
How long should my password be?
NIST recommends a minimum of 12 characters for general accounts and 16+ for sensitive accounts like email, banking, and cloud services. Longer passwords are exponentially harder to brute-force.
Should I include symbols in my password?
Including symbols significantly increases password entropy. A 16-character password with uppercase, lowercase, numbers, and symbols has over 10^30 possible combinations — effectively impossible to crack with current hardware.
What does "exclude ambiguous characters" mean?
Characters like 0 and O, or 1, l, and I, can be confused visually. Enabling this option removes them from the character pool, making manually typed passwords less error-prone.
Should I store passwords in a browser or use a password manager?
A dedicated password manager (Bitwarden, 1Password, Dashlane) is safer than browser-based storage. They encrypt your vault, support secure sharing, and work across devices and browsers.
How often should I change passwords?
Current NIST guidance (SP 800-63B) recommends against mandatory periodic changes unless there is evidence of compromise. Instead, focus on using a unique, strong password for every account.
