Secure Passwords - How to Protect Your Information from Abuse

Passwords protect your accounts and data from unauthorized access and misuse. Since there are password queries, people tend to choose passwords that we can easily remember, that are easy to type, and that may reflect our humor or lifestyle.

Sichere Passwörter - so nicht !

That is understandable in itself. However, this results in passwords such as "password", "Schalke04", or "123456". That's as safe as a key under the doormat.

Even if you say now that your account has no secrets, identity theft can still be a source of annoyance - for example, if your credit card has been charged for the purchase of a washing machine that you have not ordered or received. It is equally annoying when your mail account is abused to handle spam or even criminal matters.

Nowadays, attackers are no longer sitting in front of the keyboard, trying one password at a time manually. They use globally distributed computers to test thousands of password combinations simultaneously with sophisticated programs. The complex algorithms combine data from dictionaries, common syllables and number sequences. Of course, the "top selection" of the most popular passwords is at the top here.

Social networks and other data sources are also searched automatically to include personal data in every conceivable combination. It's easy to guess a password like "Lumpi2010" if, at some point or other, you've announced somewhere that you've had a dog named Lumpi since 2010. Of course, passwords captured on other occasions are also included in the search algorithm.


  • use upper and lower case letters, numbers, and special characters for your password.
  • Use each password for one purpose only.
  • the longer and more random a password is, the longer it will resist attacks.
  • activate the "two factor authentication" where possible (in addition to your password an additional security feature is requested.)


Be sure to avoid the following:
  • fun passwords like "secret" or "sagichnicht"
  • personal data, such as names, birthdays, sports clubs or music groups
  • Combinations on the keyboard next to each other eg "qwertz" or "5678"
  • Words that appear in the dictionary or lexicon.


  1. Take an arbitrary sentence eg: "Tonight I go to the concert with seven people."
  2. From this sentence take the first letters "HAgim7LiK."
  3. (do not use this example)



To master the multitude of login data, you can create an encrypted password database. The advantage here is that they only have to remember the password of the database. All other passwords can be really long and random and still be handy when needed. Another advantage is that with such a database, you can keep track of how old certain passwords are to renew them regularly. These types of databases are available, for example, as open source software for all common desktop and mobile operating systems.
