Introduction
In today’s digital world, passwords are the first line of defense protecting online accounts, sensitive information, and private data. Yet despite constant warnings, weak passwords remain one of the leading causes of data breaches. Creating passwords that are strong is no longer optional — it’s essential for online security.
From personal email accounts to financial platforms and work systems, a single compromised password can give hackers access to multiple accounts. This article explains what makes a password strong, why password length matters more than ever, how password managers and generators help, and how additional protections like multifactor authentication strengthen security even further.
Passwords That Are Strong
A strong password is long with at least 12 characters, complex with a mix of uppercase, lowercase, numbers, and symbols, unique to each account, and unpredictable without personal information or dictionary words.
Length is a key factor for a secure password, with at least 15 characters ideal for high security. A strong password should be at least 12–15 characters long.
Longer passwords are recommended, with a minimum of 12-15 characters, because they are much harder for hackers to crack. The longer your password is, the better it is for security. A password that is 16 characters long can take a billion years to guess using brute force techniques. A strong password can take millions of years to crack, making it less likely that hackers will try to access it.
Password Manager Basics
A password manager is one of the most effective tools for protecting login credentials. Password managers help users maintain unique passwords for every account and securely store them in an encrypted password vault.
Password managers allow users to only remember one master password to unlock their vault. Using a password manager allows users to generate and store strong passwords—long, complex passwords that would otherwise be impossible to remember—securely.
Password managers use encryption and zero-knowledge architecture to keep user data secure, meaning only you can access your stored passwords.
Random Passwords and Why They Matter
Random passwords are difficult for attackers to predict. A strong password should be a random jumble of letters, numbers, and symbols, not identifiable words or dates.
Avoid predictable patterns such as sequential numbers or common substitutions in passwords. Passwords should not contain common words, personal information, or easily guessable patterns.
The longer the password, the longer it takes for hackers to crack it using brute force techniques. Weak passwords can be cracked in a matter of minutes, while strong passwords can take years or even centuries to break.
Strong Passwords Explained
Strong passwords follow several essential rules:
A strong password should include a combination of lowercase and uppercase letters, numbers, and special symbols.
Passwords should include a mix of uppercase and lowercase letters, numbers, and special characters.
Passwords should not contain personal information such as your name, address, or date of birth.
Each password should be unique and not reused across multiple accounts. Using unique passwords for different accounts reduces the likelihood that multiple accounts could be hacked if one password is exposed.
Additionally, you should never reuse passwords across different accounts to prevent vulnerabilities from credential stuffing.
Password Generator Tools
A password generator creates secure passwords automatically. Using a password generator can help create strong, random passwords that are difficult to crack.
To generate strong passwords, aim for at least 12–16 characters, minimize reusing passwords, and avoid personal details and dictionary words to enhance unpredictability.
Many password managers include a built-in password generator that produces random characters in a secure random order.
Free Password Generator Options
A free password generator can help users create secure passwords without cost. Avast does not store any passwords generated by its Random Password Generator.
Some tools focus only on generation, while others integrate generation with secure storage. Using a trusted password manager provides both generation and long-term protection.
Creating Strong Passwords
Creating strong passwords manually can be challenging. For example, you can create a strong password by combining unrelated words into a memorable passphrase, such as "BlueCarpet7!LemonTree". Modern guidelines prioritize the total length of passwords over the complexity of characters.
Use memorable passphrases by combining several unrelated words, or utilize random strings generated by a password manager.
Passwords should not contain common words, products, characters, names, or anything else that can easily be found in a dictionary when creating passwords.
Complex Passwords
Complex passwords use a mix of uppercase and lowercase letters, numbers, and special characters. Lowercase letters, uppercase letters, numbers, and symbols all increase entropy and make passwords harder to crack.
A password that is less than eight characters long is considered weak and easily hackable. Eight-character passwords are no longer sufficient in today’s threat environment.
Strong Password Generator Benefits
A strong password generator eliminates human bias. Humans tend to create predictable passwords, while generators produce truly random characters.
Using a password generator can significantly reduce vulnerability to cyber threats and eliminate reliance on common words or patterns.
Generate Strong Passwords for Every Account
Generate strong passwords for all online accounts, including email, banking, cloud services, and work systems.
Using unique passwords for each account reduces the risk of multiple accounts being compromised if one password is leaked. Avoiding the reuse of passwords is crucial to maintaining security across multiple accounts.
Multifactor Authentication
Enabling multifactor authentication (MFA) adds an extra layer of security beyond just a password. Multi-factor authentication adds an additional layer of security to online accounts.
It is recommended to enable multi-factor authentication for every account that allows it. MFA significantly reduces the risk of unauthorized access, even if passwords are compromised.
This is an area where modern solutions like Everykey quietly fit into the security stack by reducing reliance on passwords altogether through proximity-based and passwordless authentication.
Online Security and Password Hygiene
Good password hygiene improves overall online security. Using weak passwords can lead to unauthorized access to sensitive information and accounts.
Changing passwords is only recommended when a breach is suspected, as unnecessary periodic changes can lead to weaker password practices. Regularly updating passwords is important if there is a suspicion of unauthorized access or a data breach.
Dictionary Attack Risks
Weak passwords can be easily cracked by hackers using brute-force or dictionary attacks. Common passwords, such as “123456” and “password”, are among the first that hackers try during an attack.
Avoid using common words, predictable phrases, or dictionary terms. A dictionary attack exploits known words and patterns to crack passwords quickly.
What Makes a Good Password
A good password is long, random, and unique. A strong password is difficult for hackers to crack and can take millions or even billions of years to break.
Passwords should be at least 12–15 characters long for better cybersecurity. Password length matters more than complexity alone.
Using a password manager, generating random passwords, enabling MFA, and avoiding reuse together form the strongest defense.
Common Password Mistakes
Even with growing awareness about online security, many people still fall into common password traps that put their accounts and sensitive information at risk. Here are some of the most frequent mistakes to avoid:
Using weak passwords: Simple or short passwords, such as an eight character password or common words, are easy for hackers to crack. Always create complex passwords that combine uppercase and lowercase letters, numbers, and special characters.
Reusing the same password across multiple accounts: If one account is compromised, all other accounts using that password are at risk. Each account should have a unique password to maximize password security.
Not using a password manager: Relying on memory or writing passwords on sticky notes can lead to weak passwords and security breaches. A password manager helps you securely store and generate strong, unique passwords for all your accounts.
Slightly modifying passwords for different accounts: Changing just a letter or number makes passwords vulnerable to dictionary attacks and brute-force attempts. Instead, use a password manager to create truly random, complex passwords for every account.
Neglecting multifactor authentication (MFA): Failing to enable MFA leaves your accounts protected by only one layer of security. Adding MFA significantly increases your account’s defense against unauthorized access.
Using personal information or common words: Passwords based on names, birthdays, or dictionary words are easy targets for hackers. Always create complex passwords that avoid predictable patterns.
Not updating passwords after a data breach: If your data is involved in a breach, not changing your passwords can leave your accounts exposed. Update your passwords immediately if you suspect a breach.
Storing passwords insecurely: Writing passwords on sticky notes or saving them in unprotected files can compromise your password security. Always use a secure password manager to store long and complex passwords safely.
By avoiding these mistakes and following best practices, you can greatly improve your online security and protect your private data from hackers.
