Password Generator
Create strong passwords with full control over length and character sets — uppercase, lowercase, numbers, and symbols. Strength is estimated on every generation. Runs entirely in your browser; no passwords are stored or transmitted.
Generate a strong, random password in seconds. Control the length (4–128 characters) and toggle uppercase letters, lowercase letters, numbers, and symbols. A strength indicator rates each result by estimated entropy. Everything runs in your browser — no password is ever sent to a server.
How it works
Account security
Stop reusing passwords. Generate a unique, high-entropy password for every account and store it in a password manager.
Developer secrets
Need a random API key, JWT secret, or database password? Generate a long, symbol-rich password for use in environment variables and config files.
Test credentials
Quickly generate realistic test passwords for user tables, seeding scripts, and QA automation without thinking about it.
Temporary access
Create a one-time password to share with a colleague or vendor, then rotate it immediately after use.
