  • Your password is 100% safe & secure.

How to Create a Strong Password?

A very strong and complex password should have at least 16 characters and should have a combination of upper and lower case letters.

Here are some tips on how to create a strong password.

  1. At least 16 characters - some people suggest that a good password should be at least 8 characters, but we think a 16 character password is much more secure.
  2. Contains at least one upper case letter - a strong password should contain at least 1 upper case letter, preferably a few more.
  3. Contains at least one lowercase letter - at least one lowercase letter is needed in a secure password.
  4. Contains at least one special symbol - special characters are highly recommended in a strong and secure password. You should consider adding a few more special characters for important accounts.
  5. Contains at least one number - in addition to all of the above, don't forget to include numbers in your password which makes it harder for hackers to steal your password.

Common Passwords to Avoid

Following is a list of common passwords to avoid as these kinds of passwords can be easily hacked by experienced hackers.

  1. Keyword sequences like “asdfg”
  2. Number passwords like “11111”, “1234567”, and so on
  3. Common alphanumeric passwords like “abcd12345”, “aaa1111”, “abcd888”, and so on
  4. Names of your families, friends, or pets
  5. Names of sports or common hobbies
  6. Birthday, phone numbers, postcodes, house numbers, ID card numbers, and social security numbers

You should create a different password, security questions, and answers for multiple important accounts and websites. If a hacker gained access to one of the websites or your accounts, your other accounts would still be safe.

Password entropy

The password generator also determines the password entropy, measured in bits. The higher the entropy, the more difficult it will be for the password to be guessed. In the context of a brute force search (where every possibility is tested), a password entropy of 100 bits would require 2100 attempts for all possibilities to be exhausted. On average however, about half of these possibilities would need to be exhausted before the correct one is found in a brute force search.

How to keep passwords safe?

To prevent your passwords from being hacked by social engineering, brute force or dictionary attack method, and keep your online accounts safe, you should notice that:

  1. Do not use the same password, security question and answer for multiple important accounts.
  2. Use a password that has at least 16 characters, use at least one number, one uppercase letter, one lowercase letter and one special symbol.
  3. Do not use the names of your families, friends or pets in your passwords.
  4. Do not use postcodes, house numbers, phone numbers, birthdates, ID card numbers, social security numbers, and so on in your passwords.
  5. Do not use any dictionary word in your passwords. Examples of strong passwords: ePYHc~dS*)8$+V-', qzRtC{6rXN3N\RgL, zbfUMZPE6`FC%)sZ. Examples of weak passwords: qwert12345, Gbt3fC79ZmMEFUFJ, 1234567890, 987654321, nortonpassword.
  6. Do not use two or more similar passwords which most of their characters are same, for example, ilovefreshflowersMac, ilovefreshflowersDropBox, since if one of these passwords is stolen, then it means that all of these passwords are stolen.
  7. Do not use something that can be cloned( but you can't change ) as your passwords, such as your fingerprints.
  8. Do not let your Web browsers (FireFox, Chrome, Safari, Opera, IE, Microsoft Edge) to store your passwords, since all passwords saved in Web browsers can be revealed easily.
  9. Do not log in to important accounts on the computers of others, or when connected to a public Wi-Fi hotspot, Tor, free VPN or web proxy.
  10. Do not send sensitive information online via unencrypted( e.g. HTTP or FTP ) connections, because messages in these connections can be sniffed with very little effort. You should use encrypted connections such as HTTPS, SFTP, FTPS, SMTPS, IPSec whenever possible.

These simple tips will keep you safe.
