How to Create a Strong Password (2026 Guide)

Guides · Security · Updated 2026

Weak passwords are still the leading cause of hacked accounts. The good news: creating a strong password is simple once you understand what actually makes one secure. This guide explains the rules and shows you how to generate a password that's practically impossible to guess.

What makes a password strong?

• Length: the single most important factor. Aim for at least 12–16 characters.
• Variety: mix uppercase, lowercase, numbers and symbols.
• Randomness: avoid names, birthdays, "123456" or dictionary words.
• Uniqueness: never reuse the same password across sites.

Each extra character makes a password exponentially harder to crack. A random 16-character password would take modern computers longer than the age of the universe to brute-force.

Passwords to avoid

Attackers try the obvious ones first: password, qwerty, 111111, your pet's name, or a word followed by a year. If your password could appear in a "most common passwords" list, change it today.

Step-by-step: generate a strong password

1. Open the Password Generator.
2. Set the length to 16 or more.
3. Keep uppercase, lowercase, numbers and symbols all enabled.
4. Click Generate, check the strength rating, and copy your new password.

How to remember strong passwords

You don't have to. The best practice is to use a password manager, which stores all your unique passwords behind one master password. Then you only need to remember that one strong passphrase — such as four random words joined together.

Extra protection: two-factor authentication

Even a perfect password is stronger with 2FA (a code from an app or SMS). Turn it on for email, banking and social accounts — it blocks most attacks even if a password leaks.

Frequently Asked Questions

How long should a password be?

At least 12 characters, and 16 or more for important accounts like email and banking. Length adds security faster than anything else.

Are these passwords truly random?

Yes. The generator uses your browser's cryptographically secure random number generator, not a predictable pattern, so each password is genuinely unpredictable.

Could two people get the same password?

In practice, no. The number of possible 16-character passwords is astronomically large, so the chance of a collision is effectively zero.

Should I include symbols?

Yes, when the site allows them. Symbols expand the character set and make brute-force attacks much harder. If a site rejects symbols, simply make the password longer instead.

Are generated passwords stored anywhere?

No. Each password is created on your device and is never transmitted or saved. Once you copy it, store it safely in a password manager.
