Tip: How to choose a secure password!

General rules for secure passwords!

Choose secure passwords.

How can you choose a secure password that you can remember? While this may seem complicated, there are a few very simple tips on how to succeed. Important: The examples should only show which concept I execute here and describe. there will not be just a concept suitable for choosing a secure password. The combination of several methods will result in a secure and memorable password!

  • User a mix of alphabet and numbers
  • Always use a mix of lowercase and uppercase letters
  • Use symbols that allow your system to enter (! "§ $% & / etc ..)
  • Spaces are not possible to enter with passwords!
  • Use phrases that you can remember and change them by spelling mistakes.
    Example: I like the sun! = "ICh2MaK3sohne!"
  • User special characters to express something
    Example: "iCh2MaG"> Sun! or "Ich2 (MAG)> son!"
  • Use abbreviations or special characters to deface your phrase
    Example: ich2 (MAG)> ***

Choose safe passwords!

Another technique would be to think of longer phrases and abbreviate these and save with special characters:

For example:

"The best series I've ever seen."

"DBSDIJGH"Only the initial letters

"DbSdIjGh"Initial letter alternates large / small script

"Db2Sd4Ij6Gh8"Additionally with numbers deposited" 2,4,6,8 "

"! Db2 "Sd4§Ij6 $ Gh8%"And added special characters to every third place:"! "§ $%"

Of course, this scheme can be repeated for any application or web page you choose and you can remember one sentence per application without changing your own system!

Now that you have selected the first part of your password. (He should also have at least 8 characters!) Can you also add an individual part for the application or website.

  • ebay: eB:Db2 "Sd4§Ij6 $ Gh8%
  • Amazon: Db2 "Sd4§Ij6 $ Gh8%: M a
  • Facebook: face:Db2 "Sd4§Ij6 $ Gh8%Book

So you can generate as many passwords with a scheme and you only have to remember how you change them. The best of all according to a scheme that is only known to you and that at first glance never lets you know how you think it is.

What you should never do:

  • Do not use your name, in any form, neither first name, last name, spit name or otherwise!
  • Never use dates such as birthdays, social security numbers, bank account numbers or any other way. every date is also known to somebody else!
  • Never use a part of your username in the password!
  • Best of all, do not use any names at all, not even Susi, Peter or Seppi!
  • Make passwords with at least 8 characters! Never shorter!
  • Do not use locations in the passwords: Salzburg, Munich, Hamburg etc.
  • No street names
  • No otherwise meaningful words!
  • Do not use encryption forms like:
    A = 1; B = 2; C = 3; D = 4 ... because every such simple encryption is comprehensible to others.

Why? How does security change?

If you choose a word or a number that you can understand, then the mathematical probability of being able to understand it decreases by an enormous factor!


8 characters used in a password
calculationPossible combinations
Words from the vocabulary:
(Let's say there are ~ 600,000 words)
Only pay^ 10 8100,000,000
Letters only in lowercase^ 26 8208,827,064,576
Letters upper / lower case combination^ 52 853,459,728,531,456
upper / lower case + numbers^ 62 8218,340,105,584,896
Complete combination of all printable characters(10+26+26+19)^8645,753,531,245,761

The longer a password is, the more secure it becomes:

In the process, the exponential security increases extremely with each character added:

  • 8 characters> 645,753,531,245,761 (645 trillion) combinations
  • 9 characters> 45,848,500,718,449,031 (45 Quadrillion) combinations
  • 10 characters> 3,255,243,551,009,881,201 (3 Quintillion) combinations

I refer to the following predictions of security on the following characters, which can be found on a normal keyboard:
