Password Reset Token Check — Are Your Reset Links Guessable?

DevMeth checks the 48 known AI-code failure patternsnot a penetration test or a security guarantee.

What the issue is

Password-reset tokens generated from a predictable source (like Math.random or Date.now) or that never expire let an attacker forge reset links and take over accounts.

Why AI tools generate it

AI tools mock auth with a quick reset flow, and a 'random' token built from the clock or Math.random is the fastest thing to write.

How DevMeth detects it

A code scan checks how reset tokens are generated and whether they expire, flagging predictable sources and missing expiries.

The fix, in three steps

Generate reset tokens from a secure random source (crypto.randomBytes/randomUUID) and enforce an expiry. Three steps.

FAQ

Why is Math.random unsafe for a reset token?

Math.random isn't cryptographically secure or seeded unpredictably, so tokens built from it (or the clock) can be predicted or guessed.

What makes a token expiry important?

An expiring token limits the window an attacker has to use a stolen or guessed link; a never-expiring token is usable indefinitely.

What's the fix?

Use crypto.randomBytes/randomUUID (a secure random source) and enforce a short, explicit expiry on every reset token.
