How It Works
Web Crypto API
Uses crypto.getRandomValues() for true cryptographic randomness, not Math.random().
Rejection Sampling
Eliminates modulo bias with rejection sampling and Fisher-Yates shuffle for uniform distribution.
100% Client-Side
Nothing leaves your browser. No server requests. No tracking. No storage. Completely private.
How to Create a Strong Password
Why You Need a Password Generator
Humans are terrible at creating random passwords. We default to dictionary words, birthday numbers, and predictable patterns that attackers exploit with automated tools. A password generator removes human bias entirely by using cryptographic randomness to produce passwords that are truly unpredictable.
According to security research, over 80% of data breaches involve weak or reused passwords. Using a password generator for every account is the single most effective step you can take to protect your online security.
What Makes a Password Truly Strong?
- 1. Length over complexity. A 20-character password with mixed case is stronger than an 8-character password with every symbol type. Our generator defaults to 20 characters for this reason.
- 2. True randomness. "P@ssw0rd!" has symbols and numbers but is trivially crackable. This password generator uses the Web Crypto API to guarantee real randomness.
- 3. Uniqueness per account. Never reuse passwords. A breach on one site should not compromise all your accounts. Generate a fresh password for every service.
- 4. Secure storage. Strong passwords are useless if stored in a sticky note or plain text file. Use a password manager like SatisVault that stores credentials in your existing cloud vault (Azure Key Vault or AWS Secrets Manager).
Password Generator for Cloud Secrets
Developers managing API keys, database credentials, and service accounts need especially strong passwords. This generator creates passwords suitable for storing in Azure Key Vault, AWS Secrets Manager, or any cloud secret store.
With the SatisVault browser extension, you can generate a password here and save it directly to your vault without leaving the browser. No portal, no CLI, no context switching.
Password Length Recommendations by Use Case
| Use Case | Min. Length | Recommended |
|---|---|---|
| Social media accounts | 12 | 16+ |
| Email accounts | 14 | 20+ |
| Banking and finance | 16 | 24+ |
| Cloud provider consoles (Azure, AWS) | 20 | 32+ |
| API keys and service accounts | 24 | 40+ |
| Database credentials | 24 | 40+ |
| Encryption keys and master passwords | 32 | 64+ |

Frequently Asked Questions
Is this password generator secure?
Yes. This generator uses the Web Crypto API (crypto.getRandomValues()) for cryptographically secure random number generation. Passwords are generated entirely in your browser. Nothing is sent to any server.
What makes a strong password?
A strong password is at least 16 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and special characters. Avoid dictionary words, personal information, and repeated patterns.
How long should my password be?
We recommend at least 16 characters for most accounts and 24+ characters for high-security accounts like cloud provider consoles and password managers.
Can I use this for Azure Key Vault or AWS secrets?
Absolutely! Generate a strong password here, then use the SatisVault extension to store it directly in Azure Key Vault or AWS Secrets Manager, all from your browser.
Is this password generator better than my browser's built-in one?
Browser password generators are basic and limited to one format. This generator gives you full control over password length (up to 128 characters), character sets, and shows real-time entropy analysis. For developers managing cloud secrets, the extra control matters.
Where should I store my generated passwords?
Use a password manager. If your organization already uses Azure Key Vault or AWS Secrets Manager, SatisVault lets you store generated passwords directly in those vaults from your browser. No new vendor approval needed since secrets stay in your existing infrastructure.
