Okay, let’s say you sign up for a website — maybe to order pizza or shop online. You type in a password like ilovepizza123 and move on with your life.
But wait… where does your password go? Is it saved as-is? Is someone just looking at it?
👉 Hopefully not.
Websites aren’t supposed to store your actual password. Instead, they use a trick to scramble it — kind of like turning it into a secret code that nobody can read. This process is called hashing (but don’t worry about the fancy name).
Now, here’s where the work factor comes in — and no, it’s not your office workload. Let’s explain it with a fun example.
🍞 Think of Toast
Imagine your password is a slice of bread.
Hashing is like toasting it — once it’s toasted, you can’t turn it back into bread. It’s a one-way trip.
Now, hackers out there have big toasters that can toast millions of slices every second, trying to find one that matches yours.
So what do we do?
We slow down their toaster.
That’s what a work factor does — it makes the toasting process (hashing) take a bit longer. Just a tiny bit for you (maybe a second or less), but way more for someone trying to toast (guess) thousands of slices.
⛔ Why Slow Is Good (Sometimes)
Let’s say it takes you 1 second to log in because of this “work factor” slow-down. No big deal, right?
But if a hacker tries to guess a million passwords, and each one takes 1 second?
That’s a million seconds. That’s over 11 days! 😲
So this little delay becomes a huge headache for bad guys. It makes it really hard and time-consuming for them to guess your password.
🧂 What’s This Salt Everyone Talks About?
You might also hear about something called a salt. No, it’s not kitchen salt 😄
It’s just a random thing added to your password before it’s scrambled — kind of like putting a pinch of masala on your toast so everyone’s version tastes different.
Even if two people use the same password, their “toasted” version will come out looking different because of the salt. That makes it even harder for hackers.
🛡️ So What’s the Takeaway?
- Your password is scrambled (hashed) when you save it on a site.
- A work factor slows down the scrambling just enough to make life hard for hackers.
- A salt adds randomness so even the same password looks different.
- Together, they make your password much safer — even if the website gets hacked.
💬 Final Thoughts
You don’t need to be a tech wizard to understand this stuff.
Just know: when websites say, “We store passwords securely,” they better be using salts and work factors. Otherwise, it’s like hiding a spare key under the doormat — not very smart.
And you? Just keep using strong, unique passwords. Let the work factor do the rest.
