Password Generator & Strength Checker
Generate strong, random passwords and evaluate their security strength in real time. Fully client‑side — nothing is ever sent to a server.
How to Use the Password Generator
- Set your desired length – Drag the slider or enter a value (up to 64 characters). Longer passwords are more secure.
- Choose character types – Toggle uppercase letters, lowercase letters, numbers, and symbols. At least one type must be selected.
- Generate – Click the “Generate Strong Password” button. A random password appears instantly.
- Check strength – The built‑in meter evaluates your password’s complexity and displays a score from 0 (Very Weak) to 100 (Very Strong).
- Copy or show – Use the eye icon to reveal the password and the copy button to save it to your clipboard.
Every password is generated locally in your browser — nothing is stored or transmitted.
What Makes a Password Strong?
A strong password is your first line of defense against unauthorized access. Here’s what cybersecurity experts recommend:
- Length matters most – Aim for at least 12‑16 characters. Each additional character exponentially increases the time needed to crack the password.
- Mix character types – Use uppercase (A‑Z), lowercase (a‑z), numbers (0‑9), and symbols (!@#$…). A diverse set makes brute‑force attacks far more difficult.
- Avoid dictionary words and personal info – Hackers use dictionary attacks. Never include your name, birthdate, or common phrases.
- Don’t reuse passwords – Use a unique password for every account. A password manager can help you keep track.
- Update regularly – Change passwords periodically, especially if a service has suffered a data breach.
Our generator ensures your passwords are truly random and adhere to these best practices.
