Choosing word that will be used as password can not be taken lightly. Because if it is easily to be guessed, then all personal secret was revealed. For example if you get an email but the password is easy to guess, then someone else could easily come in and see a variety of personal information inside. Not just email, but also other accounts such as Windows login account, webiste / blog, zipped files, office documents, and others. So it needs special attention on how to choose a secure password. Here are some tips for choosing password that is not easily predictable.
1. Do not use too short password
Too short number of characters on password, eg. less than 8 characters, can be easily revealed, moreover using words that are very common. When you use it on an account on internet, then it can be easily guessed using cracker programs such as Brutus. Or if used on word, excel, or other office documents, then it can also be quickly cracked by a password recovery programs. If you can only get short word, you can be combine it with number because in addition to get longer password, the combination of letters and numbers could complicate the password inroad.
2. Do not use words that is easily guessed
Usually in order to be easy to remember, then someone just uses words that is very common, such as city of birth, residence street, name of father or mother, name of the workplace office, or even own name, and so forth. As the result, someone else could easily guess it.
3. Do not use the same password for different accounts
For example if you have more than one email, it is suggested to use different passwords for each account. Do not all have the same password.
4. Do not write down username and password on a paper
Perhaps you want to easily remember when forget, then you write them on a book/paper. Believe me, that will be easily obtained by anyone else.
5. A good password always uses combinations
They can be combination of letters, numbers and symbols like ~ ! @ # $% and others. Also use combinations of uppercase and lowercase letters.
6. You can also use abbreviations.
This is for the words easy to remember. Suppose you choose your birth place and date, example: Los Angeles, September 12 1980. Then the password might be LaSpt1280.
7. Changing passwords every certain period of time(eg. every 1 month)
Some people think it is highly recommended, especially if used in an important institution such as bank and so forth.
