Question 1

How do I create a strong password?

Accepted Answer

Use at least 12–16 characters and include a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid dictionary words, names, or predictable patterns like keyboard sequences. A password generated randomly by a tool like this one is almost always stronger than one chosen by a person, because people tend to unconsciously favour patterns.

Question 2

Is it safe to use an online password generator?

Accepted Answer

Yes, as long as the generator runs entirely in your browser and never transmits the password to any server. This generator uses your browser's built-in Web Crypto API (crypto.getRandomValues) to produce the password locally. The generated password never leaves your device — you can verify this by disconnecting from the internet and refreshing the page, and it will still work.

Question 3

What is the difference between a password and a passphrase?

Accepted Answer

A password is a random string of characters — uppercase, lowercase, numbers, and symbols. A passphrase is a sequence of random common words joined together, such as 'correct-horse-battery-staple'. Passphrases can be easier to remember and type while still being very strong, because their strength comes from the number of words chosen rather than character complexity.

Question 4

How long should a password be?

Accepted Answer

For most accounts, 12–16 characters is a solid minimum when all character types are used. For high-security use cases such as master passwords or encryption keys, 20+ characters is preferable. Length is one of the most important factors in password strength — each additional character multiplies the number of possible passwords exponentially.

Question 5

Should I use a password manager?

Accepted Answer

Yes. A password manager lets you use a unique, randomly generated password for every account without needing to remember them all. The alternative — reusing passwords across sites — means that a breach on one site puts all your other accounts at risk. Most password managers also generate strong passwords themselves, complementing tools like this one.

Question 6

What makes a password easy to crack?

Accepted Answer

Short length, use of common words or names, predictable substitutions (like @ for a, or 3 for e), and reuse across multiple accounts all make passwords easier to crack. Automated cracking tools test billions of guesses per second and have precomputed lists of common passwords. A truly random password — even a short one — is far harder to crack than a 'clever' one built from personal information.

Question 7

What is entropy in password security?

Accepted Answer

Entropy is a measure of unpredictability, expressed in bits. The higher the entropy, the more guesses an attacker would need on average to find your password by brute force. A password drawn from a character set of size N with length L has approximately L × log₂(N) bits of entropy. Adding more characters to the set or increasing the length both increase entropy and therefore security.

Question 8

Can I use this for generating Wi-Fi passwords?

Accepted Answer

Yes. A strong Wi-Fi password should be at least 12 characters using mixed character types, since it is only ever typed once per device and stored by the device after that. If you need something easier to type on a TV or phone keyboard, use the Passphrase tab — four to six words with a hyphen separator is both secure and easier to enter on devices without a full keyboard.

Question 9

How is this different from my browser's built-in password generator?

Accepted Answer

Browser-built-in generators are tied to your browser's credential storage and are designed to auto-fill. This generator is standalone — you can customise length, character types, exclusions, and passphrase settings, and you can generate passwords without saving them to any account or service. It is useful for passwords you will store in a dedicated password manager or use in contexts where browser autofill is not available.
