**Two-Factor Authentication (2FA)** means you need **two things** to log in:

- **Something you know** → your password
- **Something you have** → a one-time code from an authenticator app on your phone

Even if someone steals or guesses your password, they still cannot log in without the code from your phone.

On **3DIMLI**, 2FA uses **time-based one-time passwords (TOTP)** - 6-digit codes that refresh every ~30 seconds inside your authenticator app.

### Why Enabling 2FA Is Important

#### **1. Protects Against Unauthorized Access**
Even if someone gets your password through a data leak, weak password, or keylogger, they **still cannot log in** without the 6-digit code.
This stops most account takeover attempts.

#### **2. Keeps Purchases, Uploads & Earnings Safe**
Your 3DIMLI account may contain:

- Purchased files and licenses
- Uploaded products, drafts, previews
- Earnings, payout details, transaction history

2FA helps prevent unauthorized changes to payout info, product files, or account data.

#### **3. Prevents Misuse Across Devices**
If you're logged in on multiple devices, 2FA ensures **only you** can add new ones.
A hacker trying to sign in from a new location will be blocked without the code.

#### **4. Adds a Second Lock Beyond Passwords**
Passwords are just one layer.
2FA acts like an **extra deadbolt**:

- Password = front door key
- 2FA code = additional lock

An attacker must bypass both to access your account.

### How 2FA Setup Works on 3DIMLI

#### **Step 1: Confirm/Add Your Password**

![3DIMLI Settings Security 2FA Step 1-1](https://media.3dimli.com/3DIMLI-Images/docs/Dashboard/3Dimli2FAStep1pt1.avif "2Factor Authenticator Step 1")

![3DIMLI Settings Security 2FA Step 1-2](https://media.3dimli.com/3DIMLI-Images/docs/Dashboard/3Dimli2FAStep1pt2.avif "2Factor Authenticator Step 1")

When you click **“Setup 2-Factor Authentication”**, a modal appears asking you to enter or set a password.

This prevents someone on an already logged-in device from enabling 2FA without your approval.

- If correct → you continue
- If wrong → an error appears

#### **Step 2: Scan the QR Code**

![3DIMLI Settings Security 2FA Step 2](https://media.3dimli.com/3DIMLI-Images/docs/Dashboard/3Dimli2FAStep3.avif "O2Factor Authenticator Step 2")

You will see:

- A **QR code**
- A **secret key** (backup option)

Scanning the QR code connects your authenticator app with 3DIMLI.
If the camera doesn’t work, enter the secret key manually.

#### **Step 3: Enter the 6-Digit Code**

Open your authenticator app:

- Select the entry for **3DIMLI**
- Enter the 6-digit TOTP code shown

If you enter an expired or incorrect code, simply try again with the next one.

#### **Step 4: Setup Complete**
Once accepted, 2FA is fully enabled.

Your future login flow becomes:

1. Enter email and password
2. Enter the 6-digit authenticator code

If the code is wrong or missing, login is blocked.

Some systems also offer features like:

- **“Remember this device”**
- **Backup/Recovery codes**

If available on 3DIMLI, store recovery codes in a secure location.

- Use a strong, unique password along with 2FA.
- Save backup/recovery codes securely (password manager or printed copy).

#### **When changing phones:**
- Transfer or re-setup your authenticator before wiping your old device.

#### **If you suspect account compromise:**
- Change your password
- Review and sign out of all active sessions
- Ensure 2FA is enabled and working
