Online security is one of the major issues nowadays. Today we heard a lot of stories about hacking, stolen emails, credit card fraud, password thefts and much more around us. This type of crimes is increasing every passing day.
Security is essential for everyone, but almost everybody has a great risk from hacking. No one on the internet is safe, anything can be hacked. So, we must take caution in protecting ourselves online. The strength of password plays the major role in resisting a hack. In most cases, password hack is done by brute-force attack. In the brute-force attack, the attacker guesses and try every combination of characters that are needed to guess your password correctly.
How to Choose Strong Password?
Here are some ground rules to make your password strong:
- Password length must be of minimum 8 characters: It should never be below 8 characters. Suppose a hacker trying to hack your account, the first thing he will do is brute-force attack, he will try each and every combination of characters. So, as you add every new character in your password it will increase the time taken by brute-force attack to guess your password correctly exponentially. For example, a 6 digit password can be cracked in under an hour by brute-force, but if you add 2 more digits to the password; the time taken to crack your password will be in weeks.
- Avoid using common passwords: You will not believe this, but most common passwords are “name123”. People often put their names as password and append it 123. Believe me, it’s the worst password ever. Most hackers start with this type of passwords. If it is not a hacker, it might be one of your friend fooling around, who knows you very well. He might start with your name, your kid’s name, your pet’s name or any of your favorite athlete’s name. So, if you have the password like this change it as soon as possible. Here is the list of most common passwords used by people.
- Randomize your password: After trying common passwords like “name+123”, the hacker might switch to its next weapon-“dictionary attack”. So, what is dictionary attack? In this type of attacks, the attacker tries every word from the dictionary in an attempt to crack your password. So, it will be better if you keep your password away from real words. Although it is not fully safe but “namemy123” is always better than “myname123”.
- Reverse It: Choosing a password like “g$7^hjfs*@” is probably very secure but it won’t be easy to remember as well as to type. So, you might wanna try to reverse the words. For example, instead of using “weapon”, you can use “nopaew”. As it is an easy word to remember after reversing, it has become hard to guess for the attacker.
- Insert symbols and numbers: Most of the people don’t put any special symbols in their passwords. Are you in that category? If yes, that is because you might found it hard to remember the password with special characters filled in. Don’t worry , I have a very simple trick to add special characters in your password, take a look at this password – “345nopaew#$%”.
Let’s break down the above password, I have the base word “weapon” -reversed, and 345 at the start. Then I have special symbols “#$%” which are actually just “SHIFT + 345”, written in their respective keys. So, all you need to remember is “weapon” and “345”.
- Use capital letters: Remember, our main goal is to increase the number of characters attacker has to try before guessing correct password. So, let’s do the math – small alphabet= 26 characters, numbers= 10, special characters=20 more. So, if your add just one capital letter in your password he will have another 26 character to try. So, let’s make changes in our password with first and last letter capital – 345NopaeW#$%.
So, now we have 12 character password with upper and lower case letters, special symbols and numbers. So considering the power of exponential growth, you will not believe me but it would take decades for a supercomputer to crack your password.

On the last note, don’t use the same password for different accounts, it makes hackers job easier. But remembering all this password would be hard for anyone so I would suggest making tiny changes in passwords. You can use “345nopaew” for one account and “567nopaew” for other. So, to crack the password of another account attacker will have to go through all combinations again.
So, there it is, a guide to make your password unhackable, but still, I would advise you to change your password once in 6 months. Let me know if you have any questions in the comment section below.
