Why password is important?

Why do we lock the door when all the family members go on an outing? We do it for the security of the house. Think a bit about the lock. Anybody can not open the lock by using any key because different locks have keys. A lock can not be opened with a different key. Thus, we ensure safety of our home and other valuable things with locks and keys. Now, we see a kind of lock with digits.

The lock is opened by matching the digits. The digits work as the key. But, in an age of digital technology, we have to think over the security of many other things. Perhaps you have understood what we are talking about. You have rightly guessed. We are talking about the security of our data and information. In an age of ICT, we have to use locks for the security of our important data, information and the security of software. The name of this lock is password.

Perhaps you have already learnt to create a password and use it. ICT is being used everywhere now. Our country is not an exception. As its use has been extended, the question of security becomes important. All of our personal information such as bank accounts, income tax, job, etc. have come under the digital system. Besides, our ICT devices such as computer, laptop, tablet or

smartphones are being operated with software. When we use the Internet, we can communicate with the computer or ICT devices of the remote parts of the world. Similarly, anyone can communicate and share information with us from anywhere. In this way, our personal information can be transformed to others or our ICT device may become susceptible to hacking or computer security vulnerabilities. We can ensure security to prevent this situation. There is no

alternative to secure our information and protect the software of our device. If it is protected with a password, nobody can steal our information or damage our device. But, we should remember one thing that if anybody can steal our password, he can steal our information too. Even, he can destroy it. It is like opening the lock by using a duplicate key. Therefore, we should be skilled in

creating password. We should not create any password that can easily be guessed by others or we ourselves may forget.

As most of the users create passwords like 123456 or 654321 or abcdef, it it becomes easy to steal this type of password. Considering the significance of data or information, it is important to create a unique password.

The security along with secrecy of Password ensures the security of data and information saved in a server, computer or ICT device.

If your password is not unique:

1. Virus may attack easily;

2. The hackers may take the opportunity of hacking the computer; so your

money deposited to your account may be transferred elsewhere and your

important information may be stolen by others;

3. Information saved in the ICT device may be destroyed for your weak

Password;

How can you create a unique password? It's a creative work. Your creativity can ensure the security and secrecy of your data and software. If some processes are followed, we can easily do the job.

We should be careful of the following factors while creating a unique password:

Your name, names of your family members or any personal information should not directly be used though it helps us to remember the password;

Combination of digits, signs and capital and small letters will strengthen the password. It becomes difficult for others to guess anything about it;

Password should be long;

You should not write the password or part of it either in the computer or diary in order or remember it;

Use a symbol of your own choice to remember the password; It can be your favourite poem, short story, writer, scientific invention, or any historical event.

If creativity is added to this, the password may be unique. Our password could be as follows:

MoriTeChaHina_AmiSunDarVhubanE (Rabindranath Tagore)

AmAr_AchE_wateR (Humayun Ahmed)

2BornoT2B_tHatisThe? (To be or not to be,

that is the question- From Shakespeare)

4Score&7yrsAGO (Four score and seven years ago- From the Gettysburg Address)

Changing password is an important task because a regular change of the password ensures the confidentiality of the information stored on the device and safety and security of the ICT device itself. However, passwords should be something that can be remembered.
