Most data breaches do not start with sophisticated hacking. They start with a weak, reused or predictable password. Attackers exploit human habits far more often than they break encryption, which means fixing your password habits is one of the highest-impact security upgrades you can make.
1. Reusing the same password everywhere
If you reuse one password and a single website leaks it, attackers immediately try it on your email, banking and social accounts. Always use a unique password per site — a password generator makes this effortless.
2. Using personal information
Names, birthdays, pet names and phone numbers can be found on social media and are the first things attackers guess. A secure password must contain no personal or predictable information.
3. Choosing short passwords
Modern hardware can test billions of combinations per second. Anything under 12 characters is crackable in hours. Aim for at least 16 characters for important accounts.
4. Skipping two-factor authentication
Even a perfect password benefits from a second layer. Enable 2FA wherever it is offered — an authenticator app is far safer than SMS codes.
5. Sharing passwords through chat
Messaging apps and emails are often logged, backed up or synced. If you must share access, use a password manager with a secure sharing feature instead.
6. Storing passwords in plain text
Notes apps and spreadsheets are a treasure chest for anyone who gets access to your device. Use a reputable password manager with strong master password instead.
7. Using dictionary words
Single dictionary words, even with a number appended, fall quickly to dictionary attacks. Random combinations of uppercase, lowercase, numbers and symbols are far stronger.
8. Ignoring security warnings
When a service notifies you about a data breach or a suspicious login, it is not a sales email — it is an alert. Change the affected password immediately.
9. Never updating passwords
Long-lived passwords eventually leak through breaches. For critical accounts, rotate your passwords at least once a year or whenever a breach is reported.
10. Relying on memory alone
If you try to memorise every password, you will inevitably reuse or weaken them. Let a generator create the password and a manager remember it — you only need to remember the master password.

The easiest fix is to generate a long, random password for every account and store it in a password manager. Our free tool does exactly that, with an entropy meter so you can see the strength of every password in bits before you use it.
