Password reset looks simple.
Generate token → verify → update password.
That’s how most systems are built.
But what if this process is not actually secure?
So I created a challenge on VibeCode Arena to test this idea.
And the results were surprising.
🚨 The Problem
At first glance, everything works:
- A reset token is generated
- User sends it back
- If it matches → password is updated
Simple flow.
But there’s a hidden issue.
⚠️ What Can Go Wrong?
In real-world systems:
• Reset tokens can be reused multiple times
• No expiry → token stays valid forever
• Tokens are stored in plain format
• No protection against guessing attacks
And suddenly:
👉 Anyone with the token can reset the password again
👉 Accounts become vulnerable
👉 Security is compromised
🧠 What I Observed
When AI models tried this challenge:
- Some implemented basic token matching
- Many ignored expiry logic
- Some didn’t prevent reuse
- Very few treated it as a security-critical feature
The code works.
But the system is not safe.
🔥 Try My Challenge
I created this challenge to test real-world authentication and security thinking.
👉 Try it here:

Can you:
- Prevent token reuse?
- Add expiration logic?
- Secure the reset flow properly?
💡 What Makes This Interesting
This is not just a coding problem.
It’s about:
• Security
• Trust
• Data protection
• System design
And this is where most AI solutions struggle.
🎯 Final Thought
Password reset is not just about changing a password.
It’s about protecting user identity.
And one small mistake…
👉 Can open a big security hole.
Try it and tell me 👇
Did AI handle security properly… or miss something critical?
