Lock your digital door - with passwords

Passwords are the lock to your digital door. Whether they come in the form of digits, patterns, finger or face verification; like doors in the physical world, they are the best protection against thieves. Any of these locks is better than having none at all. Nevertheless, who would lock your front door with a wooden bolt? Or give your key to everyone? Why should you do it with your digital front door?

Golden rules for strong passwords:

At least 8, preferably 16-20 characters

An individual password for each account

No patterns, personal data, simple words, famous quotes or number sequences.

The strongest passwords consist of a combination of letters, numbers and symbols. The combination should not be easy to guess. Sequences of numbers or letters such as "1234", "abcd" or "qwertz" are easy to crack. 

  • Tip
    A password manager generates and saves passwords. A recommended open-source password manager is KeePassXC (for Windows / Linux / Mac) 

Two-factor or multi-factor authentification (2FA)(MFA)
This means setting up two or more digital locks that appear one after another. Even if one password is known or published, hackers still have to go through a second authentification process, which reduces their chances of success.

Passwords can get into the wrong hands through data leaks: The website Have I Been Pwned allows to check if you have an account on a website whose data has been published due to a security problem.
