What Makes a Strong Password?
A strong password is hard for both people and computers to guess. The two biggest factors are length and variety. Every extra character multiplies the number of possible combinations, and mixing character types (upper, lower, numbers, symbols) makes brute-force attacks far slower.
| Length | Character types | Strength |
|---|---|---|
| 6–7 | Letters only | Very weak |
| 8–11 | Letters + numbers | Medium |
| 12–15 | Upper + lower + numbers | Strong |
| 16+ | All four types | Very strong |
Password Safety Tips
- Use a unique password for every account — never reuse them.
- Make it long — 16+ characters is far stronger than a short complex one.
- Use a password manager to store them so you do not have to remember each one.
- Turn on two-factor authentication wherever possible for an extra layer.
- Never share passwords by email or message.
Is This Password Generator Safe?
Yes. This generator runs entirely in your browser using your device’s built-in secure random number generator. Passwords are never sent over the internet, stored, or logged — they are created locally and disappear when you close the page.
Frequently Asked Questions
What is a good password length?
At least 12 characters, and ideally 16 or more. Longer passwords are exponentially harder to crack, so length matters even more than complexity.
Are randomly generated passwords safe to use?
Yes. Random passwords have no predictable patterns, which makes them much harder to guess than passwords based on names, words or dates.
Does this tool store my passwords?
No. Everything happens in your browser. No password is sent to any server, saved, or recorded anywhere.
Should I include symbols in my password?
Yes, where the website allows them. Adding symbols increases the number of possible combinations and makes brute-force attacks slower.
How do I remember a strong password?
You do not have to. Use a trusted password manager to store unique strong passwords for every account, and only remember one master password.
How often should I change my passwords?
Change a password immediately if a service reports a breach. Otherwise, focus on using long, unique passwords with two-factor authentication rather than changing them constantly.
Conclusion
Strong, unique passwords are the simplest way to protect your online accounts. Use the generator above to create a long, random password in one click, copy it into your password manager, and enable two-factor authentication for extra safety.
