Passwords are generated using crypto.getRandomValues() which provides cryptographically secure random numbers. No passwords are stored or transmitted.
What this tool does
Generates cryptographically strong random passwords with configurable length and character sets (uppercase, lowercase, digits, symbols). Uses the browser's Web Crypto API for true randomness.
Who it's for: Anyone creating new accounts, sysadmins rotating service credentials, developers seeding test accounts.
When to use
- •Create a strong password for a new account.
- •Rotate an old password with a longer, stronger replacement.
- •Generate API keys or shared secrets for internal services.
- •Seed test databases with randomized fake credentials.
How it works
- 1Adjust length (8-128 chars) and character classes.
- 2Click Generate - crypto.getRandomValues() produces true randomness.
- 3Click Copy to get the password onto your clipboard.
- 4Nothing is stored, logged, or transmitted.
Tips
- •16+ characters with all character classes is the modern baseline.
- •Use a password manager - never memorize generated passwords.
- •Disable symbols only when the target system rejects them (e.g. legacy databases).
