How to auto-generate passwords that are actually secure

A secure password is your first defense against unauthorized access to your personal information. While there are tools that generate strong passwords(new window), remembering these complex combinations can become a challenge.

Even if you use mnemonic devices, random passphrases, or various memory techniques to make strong passwords easier to remember(new window), managing multiple secure passwords might feel overwhelming. (Writing them down on paper is never a safe method.)

If all this seems like too much effort, this article shows you how to automatically generate strong passwords and easily store them in a secure password manager to quickly log in to your accounts later. That way, you don’t have to keep track of anything, but you can still be confident that your information is safe.

What makes a password secure

A secure password is long, complex, and unpredictable, incorporating a mix of uppercase letters, lowercase letters, numbers, and special symbols. The higher the entropy(new window), the stronger the password, making it less susceptible to attacks like brute force(new window) (where an attacker tries every possible combination) or dictionary(new window) (using common words and phrases).

Remembering a long sequence of random passwords is tough, especially when each one should be unique and changed frequently without using patterns or repetitions that might weaken security.

For instance, many organizations ask you to update your passwords every two or three months. Plus, jotting them down on a piece of paper or storing them in a document on your computer or online isn’t safe — it could easily lead to someone else getting a hold of them.

Browser-based password managers

Many web browsers have a built-in password manager. This is convenient when you’re using that browser, and you don’t have to install additional software.

However, relying solely on a browser can be risky if the browser data is compromised through malware or other security flaws. You also may not have access to your passwords on other devices or apps. Plus, browsers like Google Chrome(new window) use their password managers to lock you in to their other services that have access to your data, so you risk your privacy by exposing your password information to the service provider.

Standalone password managers

A safer solution is to use a dedicated password manager(new window) to generate, retrieve, and store complex passwords. It encrypts your password database with a master password, and that’s the only one you need to remember.

Additionally, if the password manager supports two-factor authentication (2FA)(new window), it adds an extra layer of security. Even if someone discovers your master password, they still need a second form of verification to access your accounts.

However, trust remains the most important factor when choosing a password manager, as demonstrated by the LastPass data breach(new window). Many things make a password manager trustworthy(new window), such as advanced encryption, zero-knowledge architecture, multi-factor authentication (MFA), independent security audits, open-source code, or a clear privacy policy(new window).
