Strong Password Generator
Create uncrackable passwords instantly. Customize length and character types—all generated locally in your browser for maximum security.
✅ Last updated: March 1, 2026 · Uses cryptographically strong randomization
Passwords are generated entirely in your browser. We never see or store them.
How to Use the Password Generator
- Set your preferences. Adjust the slider for password length (8‑64 characters). Tick the boxes to include uppercase letters, numbers, and symbols. At least one character type must be selected.
- Click "Generate New Password". A completely random password appears instantly. The strength bar updates based on length and complexity.
- Copy the password. Click the "Copy" button to save it to your clipboard, then paste it wherever you need it.
For maximum security, we recommend passwords of at least 12 characters with a mix of uppercase, lowercase, numbers, and symbols.
Why Strong Passwords Matter for Nigerians
- Banking & fintech: With the rise of mobile banking apps like OPay, Kuda, and PalmPay, a weak password can expose your entire account. Use unique, strong passwords for each financial service.
- Social media safety: Instagram, WhatsApp, and Facebook accounts are frequent targets. A strong password is your first line of defense against hackers.
- SIM swap protection: Combined with two‑factor authentication, a strong password makes it harder for fraudsters to access your accounts even if they compromise your phone number.
- Email security: Your email is the key to resetting all other accounts. Protect it with a password that cannot be guessed.
How We Generate Secure Passwords
We use the Web Crypto API (crypto.getRandomValues()) which provides cryptographically strong pseudo‑random numbers. This is the same standard used by secure systems worldwide.
The algorithm selects characters randomly from the chosen sets until the desired length is reached. The result is unpredictable, and no seed or pattern is stored. Everything happens in your browser memory and is cleared when you leave the page.
Frequently Asked Questions
Yes. Passwords are generated using industry‑standard cryptographic randomness. They are never sent over the internet or stored. However, safety also depends on how you store the password—consider a password manager.
This tool focuses on random character passwords, which are stronger for a given length. Passphrases (like "correct‑horse‑battery‑staple") are easier to remember but longer. We may add a passphrase mode in future updates.
No. Nothing is stored. Once you navigate away or generate a new password, the old one is gone forever.
