# How to enable Two-Step Verification (2FA)
Two-step verification (also called 2FA or MFA) adds a second security layer to your VoiceB account. After entering your password, you'll also enter a 6-digit code from an authenticator app on your phone — so even if someone gets your password, they can't sign in without your device.
Setup takes about 2 minutes.
***
### Before you start
You'll need an **authenticator app** on your phone. If you already use one, skip ahead. If not, see Which authenticator app should I use? below and install one first.
***
### Enable Two-Step Verification
1. In the VoiceB dashboard, click your **name/profile icon** at the bottom left.
2. In the menu that opens, click **Manage account**.
3. In the Account window, select **Security** from the left sidebar.
4. Next to **Two-step verification**, click **+ Add two-step verification**.
5. A **QR code** will appear. Open your authenticator app and scan it:
* Google Authenticator: tap **+** → **Scan a QR code**
* Microsoft Authenticator: tap **+** → **Other account** → scan
If you can't scan (for example, you're on the same device), most apps let you enter a setup key manually instead — look for a "manual entry" or "enter code" option.
6. Your authenticator app will now show a **6-digit code** that refreshes every 30 seconds. Type that code into the dashboard and confirm.
7. **Save your backup codes.** During setup you'll be shown a set of one-time backup codes. Store these somewhere safe (a password manager is ideal). They're the only way back in if you ever lose access to your phone.
You're done when the **Two-step verification** row shows **Authenticator application — Default**.
From now on, every time you sign in you'll enter your password and then a fresh 6-digit code from your app.
***
### How to remove Two-Step Verification
If you need to disable 2FA or switch to a new device:
1. Go to **Manage account → Security**.
2. Next to **Authenticator application**, click the **...** (three-dot) menu.
3. Choose **Remove** and confirm.
You can then set it up again from scratch with your new device.
***
### Which authenticator app should I use?
Any standard TOTP (time-based one-time password) app works with VoiceB. These are the main options:
* **Google Authenticator** *(recommended)* — free, simple, iOS and Android. Backs up codes to your Google account so you don't lose them if you change phones.
* **Microsoft Authenticator** — free, iOS and Android. Good choice if your company already uses Microsoft 365; also supports cloud backup.
* **Authy** — free, iOS, Android and desktop. Strongest multi-device support, so codes sync across your phone, tablet and computer.
* **1Password / Bitwarden** — if your team already uses one of these password managers, it can generate the codes and store your password together in one place.
> **Note:** Avoid Duo as your authenticator app if possible. It generates codes on a slightly different timing that can cause "invalid code" errors during setup. If you use Duo, enter the code quickly after it appears.
#### Installing Google Authenticator (if you don't have one)
1. Open the **App Store** (iPhone) or **Google Play Store** (Android).
2. Search for **Google Authenticator** and install it.
3. Open the app and sign in with your **Google/Gmail account** (this enables cloud backup of your codes).
4. Return to step 5 above to scan the QR code.
***
### Troubleshooting
* **"Invalid code" when entering the 6-digit code** — codes expire every 30 seconds. Wait for a fresh one and enter it right away. Also check that your phone's clock is set to update automatically; a wrong clock is the most common cause.
* **I lost my phone / changed devices** — use one of your saved **backup codes** to sign in, then go to Security and remove and re-add two-step verification with your new device. No backup codes? Contact VoiceB support and we'll reset it after verifying your identity.
* **The QR code won't scan** — use your app's manual-entry option and type in the setup key shown on screen.
