Password Generator & Strength Tester - Create Secure Passwords Online
Generate strong, random, and secure passwords instantly — and test their strength with our built-in Password Strength Tester. This free online tool helps you create unique passwords that are hard to guess and easy to copy.
What is a Password Generator?
A Password Generator creates random combinations of letters, numbers, and symbols to help you make strong passwords that protect your accounts from hacking or brute-force attacks.
You can customize:
- Password length
- Include uppercase / lowercase letters
- Add numbers and special symbols
- Avoid similar characters (like O and 0)
Click Generate Password to get a new, unique password every time.
Password Strength Tester
Type or paste any password into the strength tester box, and the tool instantly shows:
- Strength level (Weak / Fair / Strong / Very Strong)
- Estimated crack time (how long a hacker might take)
- Suggestions to improve security — add length, mix cases, include numbers and symbols
The strength meter is based on entropy calculations and character diversity, similar to what top security systems use.
