How to create a truly secure password? Here are the key rules:
- Ensure sufficient length — at least 12 characters, the more, the better,
- Use a variety of character types: lowercase and uppercase letters, numbers, and special symbols (!, @, #, \$),
- Avoid obvious sequences like 123456 or qwerty,
- Don’t use personal data — names, national ID numbers (PESEL), or birth dates,
- Avoid dictionary words — specialized tools can easily crack them.
A staggering 81% of data breaches are due to weak or reused passwords. Therefore:
- Never reuse the same password across multiple accounts,
- Create unique passwords for each account — especially for banking, work, or email.
Complex doesn’t have to mean hard to remember. A helpful method is the sentence technique: create a phrase like “My dog Azor is 5 years old and loves playing with a ball!” and turn it into a password using the first letter of each word, adding numbers and symbols — e.g., Mda5yoalpwab!
Password managers like LastPass, Bitwarden, or KeePass make managing multiple passwords easier. They secure logins with encryption and give access only to you. Additionally, they:
- generate random, strong passwords,
- automatically fill in login forms,
- analyze password security levels,
- store data in an encrypted cloud,
- offer access from multiple devices.
Safe password storage practices:
- Regularly change passwords — especially for accounts protecting important data,
- Don’t write passwords on paper or store them in unsecured files,
- Avoid saving passwords in browsers on shared devices,
- Enable two-factor authentication,
- Use password generators built into managers — they eliminate human error.
If you suspect a data breach, change your passwords as soon as possible. You can check if your data has been leaked using services like *Have I Been Pwned*.
Especially sensitive accounts (e.g., banking, email, admin accounts) require the highest level of protection:
- Biometrics — fingerprint or facial recognition,
- Physical security keys — e.g., YubiKey,
- Two-step verification — authentication app or token,
- Caution with suspicious messages,
- A good antivirus program.
