#### Why two-factor authentication matters

Two-factor authentication (2FA) is an important security feature on Facebook that helps protect your account from unauthorized access. When 2FA is enabled, Meta sends a verification code whenever:

* You log in from a new device or browser
* You attempt sensitive security changes
* Meta detects unusual login activity

This article covers the three most common 2FA tasks: finding out which number your codes go to, switching to an authenticator app for more reliable delivery, and turning 2FA off if you ever need to.

#### Getting to your two-factor authentication settings

All three tasks below start from the same place, so here's the shared path first.

**Step 1: Log in to Facebook**\
Open your browser (Google Chrome recommended) and visit `https://facebook.com`. Log in using the Facebook account that manages your Meta Business assets.

**Step 2: Open Facebook settings**\
Click your **profile icon** in the top-right corner, select **Settings & Privacy**, then click **Settings**.

**Step 3: Open Meta Accounts Center**\
On the left-hand navigation panel, locate **Meta Accounts Center**, and click the blue link **See more in Accounts Center**. This opens the Meta Accounts Center, where all security and login settings are managed.

**Step 4: Go to password and security**\
In Accounts Center, use the left-side menu and click on **Password and Security**, then **Two-Factor Authentication**. Choose the correct Facebook profile if multiple profiles are listed.

From here, jump to whichever task you need below.

#### How to check the phone number linked to your 2FA

**Check the masked delivery number**\
On the Two-Factor Authentication screen, Facebook shows where your login codes are being delivered.

{% hint style="info" %}
For security reasons, Facebook doesn't show the complete number on this screen — for example, "Code sent to: +91 \*\*\*\*\*\*32". Only the last few digits are visible.
{% endhint %}

**View the full phone number**\
Return to the **Password and Security** section in Accounts Center, locate and click on **Personal Details**, then select **Contact Info**. Meta will display the phone number saved in your account in full (unmasked), along with your email address — so you can clearly identify which number is connected to your two-factor authentication setup.

#### How to switch from SMS/WhatsApp to Google Authenticator

If your Facebook verification codes sometimes don't arrive by SMS or WhatsApp, switching to an authentication app like **Google Authenticator** is a more reliable option — it doesn't depend on network or SMS delivery and keeps working even without mobile signal.

<figure><img src="https://2303112206-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F53n17VnOICC1LtDqlENV%2Fuploads%2FmQLnIFyJNVBpsYky5bKb%2FUntitled%20design%20(83).gif?alt=media&#x26;token=ce75954a-4a7d-44e3-9e77-a5be3ca11b22" alt=""><figcaption></figcaption></figure>

**Add the authentication app as a backup method**\
From the Two-Factor Authentication screen, under **Add a backup method**, click on **Authentication App**. Facebook will ask you to verify your identity before proceeding.

**Verify using your existing method**\
A verification code will be sent to your registered phone number (SMS). Enter the code on your laptop screen and click **Continue**. You can now proceed with setting up the authentication app.

#### Setting up Google Authenticator on your phone

**Install Google Authenticator**\
On your mobile phone, go to Play Store (Android) or App Store (iPhone). Download and install **Google Authenticator**, then open the app.

**Start setup in Google Authenticator**\
Tap **Get Started**, then choose either **Continue with Google account** or **Use without an account** — either option works. Select **Scan a QR Code** and your camera will open.

**Scan the QR code**\
On your laptop screen, Facebook will display a QR code. Scan that QR code using your mobile camera, then click **Next** on your laptop.

**Enter the 6-digit code**\
Google Authenticator will now show a 6-digit code. Enter this code on your laptop screen and click **Next**. You'll see a confirmation message that Two-Factor Authentication is turned on using the authentication app. Click **Done** to complete the process.

<figure><img src="https://2303112206-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F53n17VnOICC1LtDqlENV%2Fuploads%2FxzFy8WpKglhKEfh1YJ4z%2FUntitled%20design%20(82).gif?alt=media&#x26;token=04c98b65-1af3-4ed0-9955-a9466f3771f7" alt=""><figcaption></figcaption></figure>

{% hint style="info" %}
Once Google Authenticator is successfully set up, you may choose to keep SMS as a backup, or remove SMS/WhatsApp completely (optional). Using an authentication app is generally more secure and avoids OTP delay issues permanently.
{% endhint %}

#### How to disable 2FA on Facebook

Two-factor authentication adds an extra layer of security to your account — along with your password, you must enter a verification code sent to your email, SMS, or WhatsApp. If you need to disable 2FA for any reason, here's how.

<figure><img src="https://2303112206-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F53n17VnOICC1LtDqlENV%2Fuploads%2FMfgaIgYvRCp5XDk3fyus%2FUntitled%20design%20(81).gif?alt=media&#x26;token=b09ddc70-2e0b-4ed6-a32c-d5618ac9469b" alt=""><figcaption></figcaption></figure>

**View your current 2FA method**\
On the Two-Factor Authentication screen, you'll see your current authentication method (SMS, WhatsApp, or authentication app), and a toggle button on the right side, currently turned ON.

**Turn off 2FA**\
Move the toggle button to the opposite direction (turn it OFF). A pop-up will appear asking for confirmation — click **Turn Off**.

**Final verification**\
A verification code will be sent via SMS to your registered phone number. Enter the verification code and click **Continue**. Once completed, two-factor authentication will be disabled.

{% hint style="danger" %}
Disabling 2FA reduces your account security. After turning it off, your account will only require a password for login, and anyone with your password can access your account. It's strongly recommended to re-enable 2FA as soon as you're done with whatever task required it off.
{% endhint %}

#### Key takeaways

* 2FA sends a code to your linked phone number (or authenticator app) whenever there's a new login, a sensitive change, or unusual activity.
* Facebook masks your number on the Two-Factor Authentication screen — check Personal Details > Contact Info in Accounts Center to see the full, unmasked number.
* Switching to Google Authenticator removes your dependency on SMS/WhatsApp delivery and keeps working even without signal.
* You can keep SMS as a backup or remove it entirely once Google Authenticator is active.
* Disabling 2FA means your account only needs a password to log in, so re-enable it once you're done with the task that required it off.

#### Frequently asked questions

**Why is my phone number masked on the 2FA screen?**\
Facebook only shows the last couple of digits on the Two-Factor Authentication page for security reasons. To see the full number, check Personal Details > Contact Info in Accounts Center.

**Do I need to remove SMS/WhatsApp 2FA after adding Google Authenticator?**\
No, it's optional. You can keep SMS as a backup method or remove it completely once Google Authenticator is working.

**What happens if I lose my phone with Google Authenticator installed?**\
You could get locked out of your account, so it's a good idea to keep a backup 2FA method like SMS until you're confident in your setup.

**Is it safe to keep 2FA disabled long-term?**\
No, it's not recommended. Disabling 2FA means your account can be accessed with just a password, which is a security risk.

**What's a more secure alternative to disabling 2FA entirely?**\
Instead of disabling it, consider switching to Google Authenticator for more reliable, network-independent verification.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://learn.doubletick.io/meta-business-setup/two-factor-authentication/managing-2fa-on-facebook.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
