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.
