You can create stronger passwords by focusing on length and randomness, rather than just complex character combinations. This shift in approach aligns with modern security recommendations and makes your passwords easier to manage.

Why Traditional Password Advice is Outdated
For years, the common advice for creating strong passwords involved a mix of uppercase and lowercase letters, numbers, and special characters. However, this method is no longer as effective as it once was. A password’s true strength against brute-force attacks comes from its length.
For example, a 20-character password made entirely of lowercase letters can be much harder to brute-force than an 8-character password packed with symbols, numbers, and capital letters.
Many people resort to simple substitutions like replacing “a” with “@” or “s” with “$” and adding an exclamation point at the end. Password-cracking software is designed to easily detect these predictable patterns.
These complex rules can also make passwords harder to remember, leading users to write them down or reuse them across different accounts, which ironically weakens security. Furthermore, special characters may not be consistently supported across all platforms or devices, causing usability issues.
Creating Strong Passphrases
A more effective strategy for creating secure passwords is to use passphrases. These are strings of random words or short sentences, typically ranging from 20 to 30 characters, or about four to six random words.
For instance, a passphrase like “sweet mocha apple rum” offers significant security while being easier to recall than a random jumble of characters.
You can generate such passphrases using the Diceware technique. This method involves rolling dice to select words from a predefined list, such as the EFF’s 7,776-word list. This ensures a high degree of randomness, making your passphrase much harder for attackers to guess than a predictable phrase.
Using passphrases of this length, around 20 to 30 characters, provides a strong defense against many common hacking methods. This approach simplifies password creation and management for users.
The Role of Password Managers and MFA
It is practically impossible to remember dozens or hundreds of unique, strong passwords without assistance. This is where password managers, such as Bitwarden, become essential tools. These applications securely store your unique passwords and can also generate them for you, significantly reducing the risk of password reuse across different accounts.
Additionally, implementing multi-factor authentication (MFA) wherever available adds a critical layer of security. MFA requires more than just your password to log in, using methods like app-based codes, security keys, or passkeys. Even if your password is compromised in a data breach, MFA prevents unauthorized access to your account.
MFA provides an essential safeguard, ensuring that a stolen password alone is insufficient for an attacker to gain entry. This layered security approach is vital for protecting your online accounts in today’s threat landscape.
Understanding Password Restrictions
Some older systems, particularly corporate mainframes like the AS/400 and legacy databases, may have restrictions on certain symbols. This is because these characters can have special meanings within older code or data-handling systems, potentially causing conflicts or errors. These systems often have specific requirements for password composition.
For instance, password-cracking software is often designed to anticipate common character substitutions and patterns. This means that a password with predictable substitutions might not be as secure as its complex appearance suggests. Security standards have evolved to favor length and randomness over forced complexity.
For example, consider these two passwords: 5678%^&*tyuiTYUI and 8^tyU75%*IuY6T&i. Both contain identical characters and the same number of characters, demonstrating how variations might not significantly enhance security if the underlying pattern is weak.
Key Takeaways
- Focus on password length and randomness instead of just mixing character types.
- Use passphrases of 20-30 characters, made of random words, for stronger security.
- Utilize password managers to store and generate unique passwords for each account.
- Enable multi-factor authentication (MFA) wherever possible for an extra layer of protection.
- Be aware that some older systems may restrict certain special characters.
How to Create Strong Passwords
- Choose a method for generating random words, like the Diceware technique using dice and word lists.
- Select four to six random words to form a passphrase, aiming for 20-30 characters in total.
- Install and use a reputable password manager to store your generated passphrases securely.
- Enable multi-factor authentication (MFA) on all accounts that offer it.
Frequently Asked Questions
Why is it no longer recommended to use a mix of special characters, numbers, and capital letters in passwords?
Modern password security relies more on length and randomness than on complex character mixes. Predictable substitutions and patterns that users commonly employ can be easily detected by password-cracking software, making short, complex passwords less secure than longer, simpler ones.
How can I create a strong password that is easy to remember?
You can create strong, memorable passwords by using passphrases, which are strings of random words. Aim for four to six random words, totaling around 20 to 30 characters. Tools like the Diceware technique can help generate these random word combinations.
What tools can help me manage multiple strong passwords and protect my accounts?
Password managers, such as Bitwarden, are invaluable for storing and generating unique, strong passwords for all your accounts. Additionally, enabling multi-factor authentication (MFA) wherever offered provides an essential extra layer of security beyond just your password.
Why do some systems have restrictions on certain characters in passwords?
Older corporate systems, mainframes like the AS/400, and legacy databases may restrict certain symbols. This is because those characters might have special meanings in older code or data-handling systems, potentially causing conflicts or issues when processed.
