Step 1 — Hashing is a “fingerprint” (Avalanche Effect)

Type the two inputs below. You’ll see how a single character change produces a completely different fingerprint.

SHA-256 (browser computed)
A: —
B: —
First 3 chars (A): • First 3 chars (B):
2

Step 2 — Salting changes the game (same password ≠ same hash)

Enter a salt and see how it changes the outcome. This is why stolen databases shouldn’t be cheap to crack offline.

SHA-256( salt + ":" + password )

Step 3 — MFA is a second proof (not “extra password”)

Answer this: if an attacker steals your password, what does MFA block? Your answer becomes part of your interview artifact.
