Password Generator

What Does a Password Generator Do?

A password generator creates a strong, random password for you in one click, so you never have to invent one yourself — and never fall back on the same weak password everywhere. Human-chosen passwords are predictable: birthdays, pet names, favourite teams and simple patterns like "password123" are the first things attackers try, and they are tried by automated software millions of times a day. A generator, by contrast, picks each character at random from a large pool of letters, numbers and symbols, producing a password that no guessing program can sensibly predict. This free online password generator does exactly that, with options for length and character types, plus a live strength rating.

It is useful far beyond a single account. Students securing university portals, freelancers protecting client accounts, small business owners setting up staff logins, and anyone creating a new email, banking or social media account all need a fresh, strong password each time. Security experts agree on the core rule: every account should have its own unique password, and that is only realistic if a generator does the hard work of inventing them.

How to Use the Password Generator

1. Choose a length. The default is 16 characters, which is a strong choice for most accounts. Use 12 characters as a minimum for everyday accounts, and 20 or more for email, banking and password-manager master passwords.
2. Pick your character types. Uppercase letters, lowercase letters, numbers and symbols are all ticked by default. Untick any type a particular site does not accept, but keep at least two types ticked for real strength.
3. Click "Generate password". A brand-new random password appears in the box, together with its strength rating and an entropy estimate. Click again any time for a completely different password.
4. Copy and save it. Click "Copy password" and paste it into the site you are registering on, then store it in a password manager. The recent-passwords list below the tool keeps your last five generated passwords on this page only, in case you need to grab one again before leaving.

Worked Example: A 16-Character Password

Leave the defaults as they are — length 16, with all four character types ticked — and click "Generate password". You might get something like "k7#Qm9!zX2@vB4w" (your result will differ, because every generation is random). That password is 16 characters long and mixes all four character types, which gives it a pool of roughly 90 possible characters per position. Its strength meter will read "Very strong", with an entropy of about 104 bits — meaning an attacker would need to try around 2 to the power of 104 combinations, a number so large that no computer on Earth could brute-force it in any realistic time.

Compare that with an 8-character password using only lowercase letters, such as "sunshine". Its pool is just 26 characters per position, giving about 38 bits of entropy — weak enough for modern cracking tools to break quickly. The lesson is simple: length matters more than cleverness, and mixing character types multiplies the difficulty for attackers.

What Makes a Password Strong?

Tips for Staying Secure

• Never reuse passwords. One leaked password should never unlock your email, bank and social accounts at the same time.
• Use a password manager. It remembers hundreds of unique passwords so you only need to remember one strong master password.
• Turn on two-factor authentication. Even a strong password is safer with a second step, such as an authenticator app code.
• Change passwords after a breach. If a service tells you its data was exposed, generate a fresh password for that account immediately.
• Do not share passwords by message or email. If someone genuinely needs access, use the service's own sharing or guest feature instead.
