Why are random passwords more secure?

Attackers try birthdays, phone numbers, common words and reused passwords first. A truly random password has no pattern, and the longer it is and the larger the character pool, the more attempts a brute-force attack needs.

Lowers the success rate of dictionary attacks Stops credential-stuffing attacks from spreading Raises the cost of brute-force attacks Works best alongside a password manager

Password security tips

Want to create a secure password? Here are some tips to consider

Whether you use a password generator or create your own, length, complexity and uniqueness are the three keys to building a hard-to-crack password.

📏

Use a long string of characters

A good password is not easily copied or guessed. When generating a random password, make sure it is at least 16 characters long to guard against brute-force attacks — the longer the string, the exponentially longer it takes to crack.

🔀

Increase password complexity

A randomly generated string is not only hard to predict, it also resembles no word or name. Mix upper- and lower-case letters, numbers and special symbols to render dictionary attacks useless.

🔑

Choose a unique password for every account

Never reuse passwords. Each password should belong to a single account, so that even if one service is breached, your other accounts aren't compromised too. Storing them securely in a password manager is the easiest approach.

Why should I use a password generator?

Here are the five key reasons to use a strong random password generator:

  1. Hackers can crack weak passwords in secondsCybercriminals can test millions of passwords per second with brute-force attacks, and short passwords or those based on common words fall almost instantly.
  2. Most people create easily guessed passwordsPeople tend to use predictable patterns such as birthdays, names or keyboard sequences, and such passwords are defenceless against dictionary attacks.
  3. Randomly generated passwords are far strongerA password that truly randomly assigns upper- and lower-case letters, numbers and symbols is far harder to crack than one a person thinks up.
  4. Malware steals the passwords you typeKeyloggers record everything you type. Using a generator together with a password manager to autofill reduces the exposure of manual typing.
  5. A strong password is the first step to online securityCombine it with two-factor authentication (2FA) and regular checks of breach alerts to build complete account protection.

Free Online Random Password Generator: Create Genuinely Hard-to-Crack Passwords

Thinking up a new password every time you sign up is both a hassle and prone to repeats. The ToolBoy online password generator needs no download and no sign-up: it quickly creates highly random passwords and shows their length, entropy and strength in real time.

What makes a password strong?

A strong password should be long enough, random and unique. We recommend at least 16 characters, mixing upper- and lower-case letters, numbers and the common special symbols a site allows.

Why does a password need to be unique?

If you use the same password across several sites, then once one service is breached, attackers may use the same details to try logging into other platforms.

What is password entropy?

Entropy expresses the theoretical randomness of a password in bits. Higher entropy means more possible combinations, but you should still pair it with secure storage and two-factor authentication.
