Here’s Why You Should Never Use AI to Generate Your Passwords

AI-Generated Passwords: A False Sense of Security That Hackers Are Exploiting

In today’s digital landscape, where data breaches make headlines weekly and identity theft runs rampant, cybersecurity experts have been sounding the alarm about a surprisingly common practice: using AI chatbots to generate passwords. What seems like a convenient shortcut could be leaving millions of users dangerously exposed.

The Hidden Danger in Your “Secure” AI Password

You’ve probably done it. Maybe you asked ChatGPT to create a password for your new streaming service, or perhaps you had Claude generate credentials for that online store you don’t fully trust. The output looked impressive—a jumble of characters, numbers, and symbols that would take centuries to crack, right?

Wrong.

Recent research from cybersecurity firm Malwarebytes Labs has uncovered a disturbing truth about AI-generated passwords. When researchers tested popular language models including ChatGPT, Claude, and Gemini, they discovered these AI systems consistently produced passwords that were “highly predictable” and “not truly random.”

The Numbers Don’t Lie: Claude’s Shocking Failure Rate

Perhaps most alarming was Claude’s performance. Out of 50 password generation attempts, Claude only managed to produce 23 unique passwords. Even worse, it repeated the exact same password 10 times across different prompts. That means if you and nine other people asked Claude for a password using similar wording, you’d all end up with identical credentials.

But Claude wasn’t alone in its failures. Testing across multiple AI systems—including GPT-5.2, Gemini 3 Flash, Gemini 3 Pro, and even the oddly named Nano Banana Pro—revealed consistent patterns of weakness. Some models, like Gemini 3 Pro, even included warnings that their generated passwords shouldn’t be used for “sensitive accounts.”

Why AI Chatbots Can’t Generate True Randomness

The fundamental problem lies in how large language models operate. These systems are trained to predict what comes next in a sequence based on patterns in their training data. When generating a password, the AI isn’t creating true randomness—it’s calculating the most statistically probable character combinations.

Think of it like a sophisticated autocomplete function. If the AI has seen certain password patterns during training (and it almost certainly has, given how many passwords appear in data breaches), it will naturally gravitate toward similar structures. The result? Passwords that look complex but follow predictable patterns.

The Entropy Problem: When “Secure” Isn’t Secure

Cybersecurity researchers measure password strength using a concept called “entropy”—essentially, how unpredictable a password is. The gold standard for secure passwords is around 98-120 bits of entropy. AI-generated passwords consistently fell far short, measuring only 27-20 bits in testing.

This massive gap between appearance and reality is precisely what makes AI-generated passwords so dangerous. They pass basic strength tests because they contain the right mix of characters, but their underlying predictability makes them vulnerable to sophisticated attacks.

Hackers Are Already Exploiting This Weakness

Here’s where it gets scary: cybercriminals are catching on. Security experts warn that bad actors can run the same prompts used by legitimate users, collect the AI-generated passwords, and build databases of commonly produced credentials.

Imagine this scenario: thousands of users ask ChatGPT to generate a password using the prompt “Create a strong 16-character password with letters, numbers, and symbols.” If ChatGPT consistently produces similar results for that prompt, hackers now have a ready-made list of passwords to try during automated attacks.

The Traditional Solution: Password Managers Still Reign Supreme

While AI fails at password generation, traditional password managers excel. These tools use cryptographic random number generators to create truly unpredictable character sequences. They don’t rely on training data or pattern recognition—just pure mathematical randomness.

Popular options like 1Password, LastPass, Dashlane, and Bitwarden all include built-in password generators that produce genuinely secure credentials. Better yet, they store these passwords securely and can autofill them across your devices.

The DIY Approach: Creating Secure Passwords Without Tools

Even without specialized software, you can create secure passwords manually. The key is combining unrelated words in unexpected ways. For example, take three uncommon words like “shall,” “murk,” and “tumble,” then mix them up with character substitutions: “sH@_llMurktUmbl_e.”

The beauty of this approach is that while it’s memorable for you, it’s completely random to anyone else. Just remember: never use examples you find online, as they’re no longer unique.

The Future of Authentication: Passkeys Are Here

For those seeking the ultimate in security and convenience, passkeys represent the next evolution in authentication. Instead of passwords, passkeys use cryptographic keys tied to your specific device. Logging in requires your device’s built-in authentication—whether that’s Face ID, fingerprint scanning, or a PIN.

The beauty of passkeys is that there’s nothing to remember and nothing to steal. Even if a hacker obtains your username, they can’t access your account without your physical device and biometric authentication.

Major platforms including Google, Apple, Microsoft, and Amazon now support passkeys, though adoption is still growing. For now, the best strategy combines traditional strong passwords (generated by password managers, not AI) with passkey adoption wherever available.

The Bottom Line: Convenience Comes at a Cost

As AI technology becomes increasingly integrated into our daily lives, it’s tempting to outsource everything to chatbots. But when it comes to password security, that convenience could cost you everything.

The next time you’re tempted to ask ChatGPT for a password, remember: what looks secure might be your weakest link. Stick to password managers for generation, enable two-factor authentication everywhere possible, and keep an eye out for passkey support as it rolls out across your favorite services.

Your digital security is too important to leave to chance—or to AI.
