At a glance
A secure password...
- is at least 12 characters (20 for administrative accounts) long. Basically: The longer, the better!
- contains preferably upper and lower case letters, numbers and special characters (?!%+…).
- does not contain personal data like the name of a family member, your own pet, etc.
- is not found in the dictionary.
- is not just a simple password with a single number or one of the usual special characters ($, !, ?, #) at the beginning or end of the word.
But how do you remember such a password?
A popular method works like this: Think of a sentence and use only the 1st letter of each word (or only the 2nd or last etc.). Then convert certain letters into numbers or special characters and capital letters.
For example: “I get up in the morning and brush my teeth three minutes long.” Only the first letters: “Iguitmabmttml”. “i” looks like “1”, “&” replaces the “and”, 3 replaces “three”, nouns get capitalized: “1gu1tM&bmT3Ml”.
Of course there are many other tricks and methods that work just as well.
How fast can your password be cracked?
The table shows how long your password can resist a brute force attack – that is, persistent trying of all possible combinations. The more characters you use the more possibilities there are to combine these characters. And the more combinations there are, the more time criminals need to crack the password. Therefore, they should set long passwords with different types of characters (upper and lower case letters, numbers, special characters).
