Zoom Two-Factor Authentication Setup Guide

Updated 14 November 2026 · Standard formula, shown below

This guide walks you through enabling two-factor authentication (2FA) for your Zoom account, adding an essential layer of security beyond your password. You’ll set up a verification method (like an authenticator app or SMS) that you’ll use each time you sign in, significantly reducing the risk of unauthorized access. Before starting, make sure you have access to your Zoom account and a mobile device or desktop authenticator app.

What You’ll Need

A Zoom account with admin privileges (if you’re an admin, you may need to enforce 2FA for your organization).
A smartphone or tablet with an authenticator app (e.g., Google Authenticator, Microsoft Authenticator, Authy) installed, or a phone number that can receive SMS text messages.
Access to the email associated with your Zoom account for verification.

Step-by-Step

Sign in to the Zoom web portal. Open your web browser, go to zoom.us/signin, and log in with your Zoom credentials.
Navigate to the security settings. Once logged in, click on “Profile” in the left sidebar (or your profile picture in the top-right corner and select “Profile”). Then, click on the “Security” tab near the top of the profile page.
Find the Two-Factor Authentication section. Scroll down until you see “Two-Factor Authentication”. It will show a status of “Off” or “On”. Click the “Edit” button (or “Turn On”) to start the setup.
Choose your verification method. Zoom will prompt you to select how you want to receive your verification code. Your options are:
– Authenticator App: Use an app like Google Authenticator or Authy. This is generally more secure.
– SMS Text Message: Zoom sends a code to your mobile phone via text.
Select the method you prefer and click “Next”.
Set up your authenticator app (if chosen). If you selected the app method, a QR code will appear on your screen. Open your authenticator app, tap the “+” icon to add a new account, and scan the QR code. If you can’t scan it, you can manually enter the secret key shown below the QR code. After scanning, the app will display a 6-digit code. Enter that code in the Zoom field and click “Next”.
Set up SMS (if chosen). If you selected SMS, enter your mobile phone number (including country code) and click “Next”. Zoom will send a verification code to that number. Enter the code you receive and click “Next”.
Save your backup codes. Zoom will display a list of backup codes. These are one-time codes you can use if you lose your phone or can’t receive SMS. Write these down and store them in a safe place. Click “Next” after you’ve saved them.
Confirm and enable. You’ll see a summary of your setup. Click “Enable” or “Save” to turn on two-factor authentication. Zoom may ask you to re-enter your password to confirm the change.
Test it. Sign out of your Zoom account and sign back in. You should be prompted for your password and then a verification code from your chosen method. Enter the code to verify everything works.

Common Mistakes

Skipping backup codes: Many users skip saving the backup codes, only to be locked out later when they lose their phone. Always save them.
Using SMS when it’s not reliable: If you’re in an area with poor cell reception, SMS codes may not arrive. Consider using an authenticator app instead.
Not updating the app: If you switch phones or uninstall your authenticator app without disabling 2FA first, you’ll lose access. Always disable 2FA or transfer the account in the app before switching devices.
Entering the wrong code: Authenticator codes refresh every 30 seconds. If you wait too long, the code will expire. Enter it promptly.

Tips

Use an authenticator app over SMS: SMS codes can be intercepted via SIM-swapping attacks. An authenticator app is more secure because the codes are generated locally on your device.
Store backup codes in a password manager: If you use a password manager, store your backup codes there for easy access when needed.
Keep your phone secure: Since your 2FA codes will be on your phone, make sure your phone itself has a strong PIN or biometric lock.
For admins: If you’re a Zoom admin, you can enforce 2FA for all users in your organization. Go to Admin > Account Management > Security and set the “Two-Factor Authentication” requirement to “On” for all users.

Troubleshooting

I don’t receive the SMS code. Check that your phone number is entered correctly with the country code. Also, ensure your phone has signal. If you still don’t receive it, try resending the code or use an authenticator app instead.
My authenticator app isn’t showing a code. Make sure you scanned the QR code correctly. If you entered the secret key manually, double-check for typos. Also, ensure your phone’s time is set to automatic – if the time is off, the codes won’t match.
I’m locked out of my account. Use one of your backup codes. If you don’t have them, contact Zoom support. They will need to verify your identity through other means before they can disable 2FA for you.
2FA isn’t prompting me to enter a code. If you’re using the Zoom desktop client, it may remember your device for a certain period. Check your security settings to see if “Trust this device” is enabled. You can also sign out and sign back in to force the prompt.

Frequently Asked Questions

Can I use multiple 2FA methods?

Zoom allows you to have multiple authentication apps or phone numbers set up. You can add more methods in the same Security settings page.

Will 2FA affect my Zoom meetings or recordings?

No, 2FA only affects the sign-in process. Your meetings, recordings, and other features remain unchanged.

Do I need to enter a code every time I sign in?

Yes, unless you check “Trust this device” during sign-in. Zoom will then remember your device for 30 days, and you won’t be prompted for a code on that device during that period.

What if I lose my phone?

Use one of your backup codes to sign in. After that, immediately go to your security settings and remove the lost phone’s method, then add a new one.

Can I disable 2FA later?

Yes, you can turn it off at any time by going back to the Security tab in your profile and clicking “Edit” next to Two-Factor Authentication, then selecting “Turn Off”. You’ll need to verify your identity with a code.

Is 2FA mandatory for all Zoom accounts?

It’s not mandatory for individual accounts by default, but Zoom admins can enforce it for their organization’s users. We highly recommend enabling it for your own account regardless.
