Instant Generation
retrokey generates passwords in milliseconds. No waiting, no loading screens. Click the SEED button and get a new password instantly. This speed matters when you're signing up for multiple accounts.
100% Client-Side Security
Unlike many online password generators, retrokey runs entirely in your browser. Your passwords are generated locally using the browser's cryptographically secure random number generator (crypto.getRandomValues). We never see, store, or transmit your passwords. Your privacy is guaranteed.

Full Control
Set your password length from 8 to 32 characters. Toggle uppercase, lowercase, numbers, and symbols on or off. Match any service's password requirements instantly.
Real-Time Strength Meter
See your password strength as you adjust settings. retrokey shows WEAK, MEDIUM, or STRONG based on length and character variety. Aim for STRONG for important accounts.
Works Offline
After the first visit, retrokey is cached by your browser. Generate passwords anytime, anywhere—even without internet. Perfect for travel or offline work.
Completely Free
No premium features. No hidden costs. No ads that slow you down. retrokey is free forever.
retrokey vs. Other Password Generators
vs. Password Managers (Bitwarden, 1Password, LastPass)
Password managers are essential for storing passwords, but they require signup and setup. retrokey is faster for quick password generation—no account needed. Use both: generate with retrokey, store in your password manager.
vs. Browser Built-In Generators
Your browser can generate passwords, but they're often weak or limited. retrokey gives you full control: set exact length, choose character types, see real-time strength feedback.
vs. Other Online Generators
Many online generators transmit your passwords to their servers, load tracking scripts, or show intrusive ads. retrokey runs entirely in your browser—your passwords never leave your device. No tracking, no servers, no privacy concerns.
How to Use retrokey
- Visit retrokey: Go to retrokey.ulula.tools
- Set your preferences: Choose password length (8-32 characters) and character types.
- Check the strength meter: Aim for STRONG (green) for important accounts.
- Copy the password: Click the password display to copy it to your clipboard.
- Use it: Paste it into the password field on any website or app.
- Store it: Save it in a password manager like Bitwarden or 1Password.
Password Strength Guidelines
How long should your password be?
- Email: 16+ characters (your email is the key to all other accounts)
- Banking: 16+ characters (protects your money)
- Social media: 12-16 characters
- Shopping: 12-16 characters
- Streaming services: 12 characters
- Throwaway accounts: 8-12 characters
Rule of thumb: Longer is always better. A 16-character password is exponentially harder to crack than a 12-character one.
Security Best Practices
- Use unique passwords: Never reuse the same password across multiple accounts.
- Use a password manager: Store generated passwords in Bitwarden, 1Password, or LastPass.
- Enable two-factor authentication: Add a second layer of security to important accounts.
- Check for breaches: Use Have I Been Pwned to see if your email has been compromised.
- Update regularly: Change passwords for important accounts every 3-6 months.
