How to Generate a Strong Password
- Set your password length — drag the slider to choose how many characters you need. A minimum of 16 characters is recommended for most accounts.
- Choose your character types — select any combination of uppercase letters, lowercase letters, numbers, and symbols.
- Exclude similar characters — enable this option to avoid easily confused characters such as 0, O, l, and I.
- Generate — click the Generate Password button to create your password instantly.
- Copy and use — click to copy your password to the clipboard and paste it wherever you need it.
What Makes a Password Strong?
A strong password is one that is difficult for both humans and automated tools to guess or crack. The four factors that matter most are length, complexity, randomness, and uniqueness.
- Length — the longer the password, the harder it is to crack. 16 characters is a solid baseline; 20 or more is better for high-value accounts such as email or banking.
- Complexity — a mix of uppercase letters, lowercase letters, numbers, and symbols increases the number of possible combinations exponentially.
- Randomness — passwords based on words, names, dates, or predictable patterns are significantly easier to crack. A truly random password generated by a tool is always stronger than one you create yourself.
- Uniqueness — using the same password across multiple accounts means a single breach compromises everything. Every account should have its own unique password.
Why Use a Password Generator?
Most people create passwords based on things they can remember — names, birthdays, favourite words, or simple patterns. These feel secure but are predictable, and predictable passwords are the first thing an attacker tries.
A password generator removes human bias entirely. It produces a random string of characters based on your chosen criteria — a password that follows no pattern, contains no personal information, and cannot be guessed through social engineering or dictionary attacks.
Nesdzo’s Password Generator uses cryptographic randomness to ensure every password it creates is genuinely unpredictable. Your password is generated locally in your browser and never transmitted anywhere — so there is no risk of interception.

Frequently Asked Questions
How long should a password be? At least 16 characters for most accounts. For high-value accounts such as email, banking, or your password manager’s master password, use 20 characters or more. Longer is always better.
Is my generated password saved anywhere? No. Nesdzo’s Password Generator runs entirely in your browser. Your password is never sent to any server, never logged, and never stored. Once you leave the page, it is gone.
What does “exclude similar characters” mean? It removes characters that look alike in certain fonts — such as 0 and O, or l and I — to avoid confusion when reading or typing a password manually.
Should I use all character types? Yes, where the website or application allows it. Using uppercase, lowercase, numbers, and symbols together maximises the complexity of your password and makes it significantly harder to crack.
Can I generate a password with exactly 10 characters? Yes. Use the length slider to set any length you need, including 10 characters. For most purposes a longer password is recommended, but the generator supports any length you require.
What is the difference between a password generator and a password manager? A password generator creates strong passwords on demand. A password manager stores and organises your passwords securely. The two tools complement each other — use a generator to create strong passwords, then store them in a password manager.
Is this password generator free? Yes. Nesdzo’s Password Generator is completely free with no limits, no sign-up, and no subscription required.
