Know your password before someone else does.

Brute Force Attack

A brute force attack is one of the simplest and most common methods used by hackers to crack passwords. Automated software repeatedly guesses different password combinations until the correct one is found — modern computers can attempt billions of guesses per second, making short or simple passwords very easy to break.

Passwords like 123456, password, qwerty, or abc123 can often be cracked within seconds. The time required depends mainly on length and complexity: a short password with only letters can be cracked very quickly, while a long password mixing uppercase, lowercase, numbers, and symbols can take years or centuries.

To protect yourself, use passwords at least 12–16 characters long with a mix of letters, numbers, and special characters, and enable two-factor authentication (2FA) wherever possible.

Dictionary Attack

A dictionary attack tries a large list of commonly used passwords and words instead of every possible combination — these lists often come from dictionaries, leaked password databases, and collections of frequently used passwords.

Passwords such as welcome123, football, qwerty, iloveyou, and password123 are commonly found in these lists. Attackers may also try slight variations, like adding numbers or symbols to common words.

Avoid common words or simple phrases. Combine unrelated words with symbols, or use a password generator or password manager, to create something genuinely difficult to guess.

Phishing Attack

Rather than guessing a password with software, attackers manipulate people into giving it away. A fake email or message, made to look like it's from a trusted organization, asks the user to "verify their account" or reset their password via a link — leading to a fake page that captures whatever is entered.

Phishing is effective because it targets human behavior, not technical weaknesses — even experienced users can fall for a well-designed message.

Always check the website address before entering login details, avoid clicking suspicious links, and enable 2FA so a stolen password alone isn't enough.

Credential Stuffing

Credential stuffing reuses usernames and passwords stolen from one data breach to try logging into other, unrelated sites — it works because so many people reuse the same password across multiple accounts.

If a shopping site and a social media account share the same login, a breach at one exposes the other. Automated tools can test thousands of these combinations within seconds.

Use a different password for every account — a password manager makes this practical — and check periodically whether your credentials have appeared in a known breach.

What is an email data breach?

An email data breach occurs when hackers gain unauthorized access to a database containing user information such as email addresses, passwords, and personal details — often when a website is hacked or a company fails to secure its systems properly. Once stolen, this data is frequently sold or shared on underground forums.

Why you should check your email

Checking your email against breach databases helps you identify whether your information has been exposed in past security incidents. If it has, attackers may attempt to access your accounts using stolen credentials or techniques like credential stuffing.

What to do if your email is compromised

Act immediately: change your passwords, especially for important accounts like banking, email, and social media, and always use strong, unique passwords for each. Enabling two-factor authentication (2FA) significantly reduces the risk of unauthorized access even if a password leaks.

How to protect your email from hackers

Avoid using the same password across multiple websites and be cautious of phishing emails that try to trick you into revealing login details. Regularly updating your passwords and using a password manager greatly improves your overall security.

Use long passwords

Length is one of the most important factors in password security — at least 12 to 16 characters is significantly harder to crack than shorter ones, since automated tools can test millions of combinations per second.

Combine different character types

A strong password mixes uppercase letters, lowercase letters, numbers, and special symbols — making it much harder for attackers to guess than a simple word.

Avoid common words and patterns

Passwords like "password123", "qwerty", or "welcome" are extremely easy to crack because dictionary attacks rely specifically on lists of frequently used passwords.

Do not reuse passwords

Using the same password across multiple sites means one breach compromises them all. Always use a unique password for each account to limit the impact of any single breach.

Use passphrases instead of words

A passphrase — a combination of random words like "BlueTiger$Mountain92" — is easier to remember but still very secure, and much harder for brute force attacks to crack than a short, complex password.

Enable two-factor authentication (2FA)

Even a strong password can be compromised. 2FA adds a second verification step, ensuring that a stolen password alone still isn't enough to access your account.
