What is Password Strength?

Password strength is an important security measure used to protect online accounts and sensitive data. It refers to the ability of a password to resist guessing or brute-force attacks, and is often measured in terms of length, complexity and randomness.

What is Password Strength?

This article will explain what password strength is and provide practical examples that beginners can use to create strong passwords with ease. Additionally, helpful tips for creating secure passwords will be provided in order to further enhance account security.

Definition of Password Strength

Understanding the strength of a password is an important factor in keeping personal information secure. Password strength refers to the complexity of a chosen password, which helps to protect against malicious attacks and unauthorized access.

A strong password has at least eight characters and includes lowercase and uppercase letters, numbers, and symbols. For example, ‘P@sSw0rD’ is considered much stronger than ‘password123’. Additionally, passwords should not contain any personal information such as a birthdate or address.

Strong passwords are also unique for each account; using the same password across multiple accounts reduces security significantly. Finally, it is recommended that users change their passwords periodically to reduce the risk of unauthorized access.

Practical Examples of Password Strength

Strengthening passwords is a critical step for anyone wishing to protect their online accounts. Password strength is defined as the ability of a password to resist being guessed or cracked by malicious actors or computer programs.

Practical examples of password strength include using long passwords, special characters, and avoiding common words such as “password” or “qwerty” that could be easily guessed. It is also important to use different passwords for each account so that if one account is compromised, the other accounts will remain secure. Additionally, changing passwords regularly can help increase security further.

Using two-factor authentication (2FA) and biometric authentication are also methods to strengthen online accounts and can provide an added layer of protection against cyberattacks and unauthorized access.

Tips for Creating Strong Passwords

Creating strong passwords is a key step to protect online accounts from malicious actors and cyberattacks.

Creating secure passwords requires using a combination of upper-case and lower-case letters, numbers, and symbols. Passwords should also be at least eight characters long in order to make it more difficult for hackers to guess them.

It is also important to avoid using the same passwords for multiple accounts, as this increases vulnerability if one account is compromised.

Additionally, users should avoid common words that can be easily guessed or found in the dictionary, as well as personal information such as birthdays or family names.

Finally, users should consider using a password manager like LastPass or 1Password to securely store their passwords and generate new ones with greater complexity than humans would typically create on their own.


Password strength is an important factor for keeping accounts secure. It is essential to create passwords that are difficult for others to guess, and also remember them without having to write them down. Passwords should be long and complex, containing a combination of numbers, letters (upper and lower case) as well as special characters.

Additionally, it is important to use different passwords for each account or service. By following these guidelines when creating a password, users can help ensure their account security against malicious actors. Regularly updating passwords further reinforces the security of online accounts and helps keep personal information safe from unauthorized access.

Password strength is a measure of the effectiveness of a password against guessing or brute-force attacks. It estimates how many trials an attacker who does not have direct access to the password would need, on average, to guess it correctly. The strength of a password is a function of length, complexity, and unpredictability (source: Wikipedia).
