​​How to avoid low password entropy and create a strong password

What is Password entropy? In one word, it is a measurement that can rate how unpredictable a password is.


Password entropy is calculated by the character set used (which can be extended by using lowercase, uppercase, numbers, and symbols) and the length. Password entropy predicts the difficulty of cracking a given one by guessing, brute force, dictionary attacks, or other common methods.


Password entropy is usually expressed in bits: the entropy of a known password is zero; Half the probability of a guess on the first attempt is 1-bit entropy. The entropy can be calculated by calculating the entropy of each character, which is the number of characters in the base of 2 multiplied by the logarithm of the number of characters in itself.

How to avoid low password entropy?

Surely you can't just consider password entropy, otherwise, it will be too long, too complex, and difficult to remember. Best practices include using things that users remember but aren't easily guessed by others. Since length is one of the most important factors affecting password entropy and overall strength, longer ones may be simpler than shorter ones, but still work.


When it comes to avoiding low password entropy, a password manager is always the best solution. For example, using Passwarden’s secure password generator feature, it is very convenient to create a complex combination, including numbers, capital letters, and symbols, and instantly save it to an encrypted data store. Of course, if you prefer to use one easy-to-guess combination for all your accounts, there’s no need for a manager; but if you do care about the safety of your web assets, we highly recommend you try Passwarden, it is by far the best password manager in the market.

What are the effective features to create a high entropy password?

Password Generator 

The secure password manager provides a powerful and simple-to-use password generator. One of the biggest advantages of this feature is it can customize lengths, as well as the ability to decide whether it’s needed to use numbers, uppercase letters, or symbols. It is at the same time very convenient to create a complex password that combines digits, upper- or lower-case letters, and symbols, and immediately save the newly created one to the encrypted storage.


Besides, you can easily use Passwarden on as many devices as you like. Our strong password manager comes with a generator that can help you create high entropy passwords is now available on iOS, Android, macOS, Windows, and many browsers such as Chrome, Firefox, Edge, and Opera. 


Security Dashboard

This is a feature that will help you prevent security breaches from weak passwords. It allows you to check how strong the passwords are, and you'll be constantly notified when they're compromised or reused. Here are some of the types of passwords that will be identified by security dashboard:

  1. Weak
    These are the ones that were created without complying with requirements, or the low password entropy ones. The combinations usually do not have special symbols, numbers, lowercase, or uppercase letters. Our strength checker will provide you with the ability to change it to a stronger one.
  2. Reused
    They are reused on multiple accounts. Remember, even when you’ve created a strong and reliable combination for one account, reusing it can compromise your data on all your accounts. The best practice is always to create a unique and strong password for each account.
  3. Expiring
    Our security checker can notify you of the expiration date of the passwords and other sensitive data. It’s quite flexible to set and you may simply set a date when you wish to receive relevant notifications about changing credentials
  4. Vulnerable
    Vulnerable passwords may be the ones that have been exposed in a data breach. You will have to change it to a new and reliable one to avoid any trouble. With our detector, you can protect your data from leakage.
