SUMMARY OF HOW TO CREATE STRONG PASSWORDS AND MANAGE THE SAFEST PASSWORDSFor personal accounts such as Gmail, Facebook, Instagram accounts, etc., the best advice for you is to use strong passwords to protect your account from being logged in and illegally used by others. permission.Choosing a password for personal accounts such as Email, bank accounts, social networks … is similar to choosing a lock to store your treasure. If the lock is outdated or too simple, you can lose your property to hackers.In the article below, the network administrator will introduce you to some ways to create strong passwords and manage account passwords securely.

What is a strong password?

A strong password is one that you cannot guess or crack using a Brute Force attack. Hackers use computers to try different combinations of letters, numbers, and symbols to find the right password. Modern computers can crack short passwords consisting of only letters and numbers in seconds.

As such, a strong password consists of a combination of upper and lower case letters, numbers, and special symbols, such as punctuation marks. They must be at least 12 characters long, even longer the better.

Overall, here are the key characteristics of a good, secure password:

 

  • Be at least 12 characters long. The longer the password – the better.
  • Use upper and lower case letters, numbers and special symbols. Passwords that include mixed characters are harder to crack.
  • Does not contain easy to remember keyboard sequences.
  • Not based on your personal information.
  • Passwords are unique for each account you have.

When you set up an online account, there will often be a prompt prompting you to include numbers or certain characters. Some can even prevent you from setting a “weak password,” which is usually an easy-to-guess combination of words or numbers.

But even if you’re not prompted to set a strong password, it’s really important to do so, whenever you set up a new online account or change the password for any existing account .

 

So how to choose a password?

Today’s experts advise us: “Choose a sentence of your own and its meaning must be personal”. This makes your password unique but easy for you to remember.

  1. Effective password generation and management program

With each website that requires creating an account to be used like Facebook, Instagram, etc., it is extremely difficult to “remember” login passwords because each account will have its own password. .

Therefore, using a password management program is the solution to help you manage the most effective “password chain”. Just create a password that is strong enough and easy to remember.

If you use a password manager, there’s only one thing you need to remember, and that’s your master password. Think of a password manager as a digital vault that keeps all your logins secure. You just need to enter the correct code to access that store of information.

So, try one of the methods in the following section of the article to create a master password, then use that to store the rest of the passwords. This also means that you can come up with really special codes that no one else would think of – because you don’t even have to remember them.

It’s important not to use the same password for multiple accounts, and password managers simplify that.

Some good password managers also generate your passwords for you, so you won’t even have to create your own!

There are many effective password managers that you can choose from. But to choose the best management program, perhaps Dashlane.

  • Download Dashlane to your device and install it here.

Dashlane can easily use applications on a single platform, the program is also integrated on Web browsers and basic features are completely free to use.

If you want to sync passwords across different devices, you’ll have to “upgrade” to a premium account. However, the advice for you is to use the free version to “test” before deciding to spend your own money to buy.

In addition, Dashlane is also integrated with thousands of security features, changing passwords, …. If you are worried about security issues, just create a password of sufficient strength and use the programs. a password manager like Dashlane for the most efficient password management.

  1. Tips for creating strong passwords

2.1. Create a password with at least 12 characters

Choose a password of sufficient length, between 12 and 14 characters is reasonable. Multi-character passwords are always more secure than passwords with fewer characters.

2.2. Combination of alphanumeric characters, symbols, uppercase letters, lowercase letters

Using a password consisting of different characters further increases the security and safety of your account. When using these types of passwords, it is difficult for hackers to “hack” your account password.

2.3. Create a rhyming password – Nursery Rhymes

The method that many people like to use, and is also able to ensure good security policies on the Internet, even those that require passwords up to 15 characters long, is the rhyming password method.

You can rely on a verse, your favorite sentence, count the number of syllables, choose the first letter of each syllable to combine into a secure password. At the end of the password, you can add special characters such as exclamation point, question mark, etc.

For example: “Today it is very sunny. Kittens go to school with nothing.”

Is a verse familiar to you. So the password you can generate is:

“6hntnccMcdhcmtg!”

It’s a strong password, 16 characters long including numbers, uppercase, lowercase letters and at least one special character.

2.4. A sentence from a song or the name of your favorite movie

A similar method is applied to a password taken from a verse in a song or movie title you like. Using a movie you like, but few people know will make the password even more secure. You can also replace it with the names or famous sayings of the characters, combined with the numbers specified for the first letter of a syllable to make the password more difficult to guess.

 

Example with a sentence of the character Al Pacino in the famous movie Scent of a Woman:

“If I were the same man that I was thirty years ago I’d take a flamethrower to this place!”

Replace the character “t” with the number 3. This quote then becomes the password:

“IIw36m3Iw3yaI3af33p!”

The concept is basic cryptography 101, but here’s how to create a password that’s hard for hackers to hack into your account, but still easy for you to remember.

2.5. Use Technical Terminology

Another interesting method is to use technical terms in different professions. Each is an expert in his or her own career field. Based on that, you can choose a technical term that you are familiar with to create a strong password.

For example, if you are a nurse, or a doctor, phrases you may have to memorize for sure to work are:

“ARDS: Acute respiratory distress syndrome: acute respiratory distress syndrome”

You can replace the character “a” with a zero to create your own password like this:

“A0rdshcspct#”

This is just a 12-character password, but it’s hard to guess.

 

2.6. Your special day

Another method for creating strong and easy to remember passwords is mainly numbers. Of course, random numbers will make you forget. You should choose numbers based on dates that are particularly important to you.

This method makes many people immediately think of using birthdays. However, this is especially flawed because those are numbers that others can know very easily, especially hackers. So you should choose a date to record an event that is special to you but no one knows but you.

For example, it was the day that you first got a bicycle. The day you kissed for the first time. The day you travel abroad…

 

So you have 3 important dates. You put those numbers on the same password and separate it with dashes, ending with a special character like a pound sign.

For example:

“10l08l86_03l14l94_09l06l98#”

This password is up to 20+ characters, so it can only be used in systems that can handle very long passwords. However, it will give you one of the most secure passwords. You can take a day off to reduce the number of characters to match the password requirements in your account.

2.7. Use keymap

Like the password method in smartphone models. You rely on the keyboard pattern to generate your own passwords.

 

With this method, you can draw recognizable images or letters on the keyboard. In the above case, the generated password is:

“3waxcvgy7890-=”

Using this method you can change to lengthen the password. A hacker could potentially run an algorithm to figure out your password, so it’s a good idea to invent more complex patterns such as one-key travel, diagonal travel to keep your password secure. friend.

2.8. Make a rough password and divide it into parts

This method makes the password secure, but it is crude and easy to implement.

You create passwords and print them out into 2 different cards. Each separate card will be part of the password that you need to remember.

For example, your password might be “2BeOrNot2BeThatIsThe?”

So you will have the tag “ThatIsThe?” to remind of “2BeOrNot2Be” and can be stored in 2 different places.

The value here is that even if someone finds your password part, they still won’t have the other half only you remember.
