How to Add Eufy to a Second Phone

If you’ve invested in a Eufy smart home security system—whether it’s doorbell cameras, indoor cams, or outdoor sensors—you’ll want to share access with family members, roommates, or trusted employees. The good news? Adding Eufy to a second phone is simple, secure, and doesn’t require buying extra equipment. Whether you’re setting up access for your spouse, a babysitter, or a property manager, this guide will walk you through every step to ensure a smooth and reliable experience.

In this comprehensive how-to guide, you’ll learn how to add Eufy to a second phone using the Eufy Security app. We’ll cover everything from downloading the app and creating accounts to sending invitations, setting user permissions, and troubleshooting common issues. By the end, you’ll be able to confidently share control of your Eufy devices with others—keeping your home secure while giving loved ones peace of mind.

Let’s get started.

Why Share Eufy Access with a Second Phone?

Before diving into the steps, it’s worth understanding why sharing Eufy access is beneficial. Eufy devices are designed for real-time monitoring, motion detection, and two-way audio, making them ideal for home security. But what good is a security system if only one person can access it?

Imagine this: You’re at work, and your child arrives home from school. With Eufy access on their phone (or a parent’s), they can check the doorbell camera, talk to someone at the door, or alert you if something seems off. Or perhaps you’re on vacation, and a neighbor is watering your plants. They can arm or disarm your system remotely, ensuring your home stays protected.

Sharing access also helps in emergencies. If you’re unreachable, a trusted family member can view live footage, receive alerts, or even contact authorities if needed. Plus, Eufy’s local storage and end-to-end encryption mean your data stays private—even when shared.

In short, adding Eufy to a second phone enhances convenience, improves responsiveness, and strengthens your home’s security network.

What You’ll Need Before Starting

Before you begin, make sure you have the following:

• A primary Eufy account: This is the account that originally set up the devices. Only the primary user can send invitations.
• The Eufy Security app installed on both phones: Available for free on the App Store (iOS) and Google Play (Android).
• Stable internet connection: Both phones should be connected to Wi-Fi or have strong cellular data.
• Email address or phone number of the second user: This is required to send the invitation.
• Eufy devices already set up: Your cameras, doorbells, or sensors should be installed and functioning on the primary account.

Having these ready will save time and prevent interruptions during the setup process.

Step 1: Open the Eufy Security App on the Primary Phone

Start by opening the Eufy Security app on the phone that’s already linked to your devices—this is your primary account.

Once the app loads, you’ll see the home screen with a list of your connected devices. Tap the menu icon (usually three horizontal lines or a profile icon) in the top-left or top-right corner.

From the menu, look for an option labeled “Family & Guests” or “User Management”. This is where you’ll manage who has access to your Eufy system.

If you don’t see this option, make sure your app is updated to the latest version. Older versions may have slightly different menus.

Tip: Keep Your App Updated

Eufy frequently releases updates to improve performance, add features, and fix bugs. To check for updates:

• On iPhone: Open the App Store > tap your profile > scroll to Eufy Security > tap “Update” if available.
• On Android: Open Google Play > tap the menu > “My apps & games” > find Eufy Security > tap “Update.”

An outdated app can cause compatibility issues when sharing access.

Step 2: Invite a New User

Once you’re in the Family & Guests section, tap the “+” or “Add User” button.

You’ll be prompted to enter the email address or phone number of the person you want to invite. Make sure this is accurate—Eufy will send the invitation to this contact.

After entering the information, tap “Send Invitation.”

The system will generate a secure link that’s sent via email or SMS. This link allows the second user to join your Eufy network.

Example: Inviting a Family Member

Let’s say you want to give your spouse access. You enter their email (e.g., sarah@example.com), tap send, and they receive a message like:

“You’ve been invited to access the Eufy Security system for [Your Name]’s home. Tap here to accept.”

They’ll need to tap the link to proceed.

Important: Only Primary Users Can Invite

Only the account that originally set up the devices can send invitations. If you’re not the primary user, you’ll need to ask the account owner to send the invite.

Step 3: The Second User Accepts the Invitation

Now, the second phone comes into play. The invited user must:

1. Open the email or SMS containing the invitation.
2. Tap the link provided.
3. This will open the Eufy Security app (or prompt them to download it if not installed).
4. If they don’t have a Eufy account, they’ll need to create one using the same email or phone number.
5. Once logged in, they’ll see a prompt to accept the invitation.
6. Tap “Accept” to gain access.

After accepting, the second user will see your Eufy devices in their app. They can now view live feeds, receive alerts, and control devices based on the permissions you’ve set.

Tip: Use the Same Email for Consistency

To avoid confusion, encourage the second user to create their Eufy account using the same email address that received the invitation. This ensures a smooth connection.

Step 4: Set User Permissions

Once the second user accepts the invitation, you (the primary user) can customize their access level. This is crucial for security and convenience.

Go back to the Family & Guests section in your app. You’ll see the new user listed. Tap on their name to edit permissions.

Eufy typically offers three permission levels:

• Viewer: Can view live feeds and recordings but cannot arm/disarm or change settings.
• User: Can view, arm/disarm the system, and receive alerts. Cannot add or remove devices.
• Admin: Full access—can manage devices, invite others, and change system settings.

Choose the level that fits the user’s role.

Example: Setting Permissions for a Babysitter

If you’re inviting a babysitter, you might set them as a Viewer so they can check the indoor camera but can’t change any settings. For a co-parent or roommate, User access makes sense—they can arm the system when leaving.

Avoid giving Admin access unless absolutely necessary, as it allows full control over your security setup.

Can You Change Permissions Later?

Yes! You can adjust permissions anytime by revisiting the Family & Guests section and editing the user’s profile.

Step 5: Test the Connection

After setting permissions, it’s important to test the connection to ensure everything works.

Ask the second user to:

• Open the Eufy Security app.
• Check if all devices appear on their home screen.
• Tap on a camera to view the live feed.
• Test motion alerts (if applicable) by walking in front of a sensor.
• If they have User or Admin access, try arming and disarming the system.

If any device is missing or unresponsive, go back to the primary account and verify that the user has the correct permissions.

Common Test Scenarios

• Doorbell camera: Have the second user check if they can see the live view and hear audio.
• Indoor camera: Test two-way talk by speaking through the app.
• Security system: Arm the system from the second phone and confirm it activates.

Testing ensures both users can rely on the system when needed.

Troubleshooting Common Issues

Even with careful setup, you might run into problems. Here are solutions to the most common issues when adding Eufy to a second phone.

Issue 1: Invitation Not Received

If the second user doesn’t get the invitation:

• Check the spam or junk folder in their email.
• Verify the email or phone number was entered correctly.
• Resend the invitation from the primary account.
• Ensure the second user’s device has internet access.

Sometimes, carrier filters block SMS invites. In that case, use email instead.

Issue 2: App Crashes or Freezes

If the Eufy app crashes on the second phone:

• Close and reopen the app.
• Restart the phone.
• Clear the app cache (Android: Settings > Apps > Eufy > Storage > Clear Cache).
• Reinstall the app if problems persist.

Outdated operating systems can also cause instability. Make sure both phones are running iOS 12+ or Android 7+.

Issue 3: Devices Not Showing Up

If the second user can’t see any devices:

• Confirm they accepted the invitation and logged in.
• Check that the primary user granted the correct permissions.
• Ensure the devices are online (check the primary app for connectivity status).
• Log out and back into the Eufy app on the second phone.

Sometimes, a simple refresh (pull down on the home screen) updates the device list.

Issue 4: Delayed Alerts or Live Feed

If live video is laggy or alerts are delayed:

• Check the Wi-Fi signal strength at the camera location.
• Ensure the second phone has a strong internet connection.
• Reduce video quality in the app settings (e.g., switch from HD to standard).
• Restart the Eufy device by unplugging it for 10 seconds.

Eufy devices rely on local processing, but streaming still depends on network speed.

Issue 5: Permission Errors

If the second user can’t arm the system or access certain features:

• Go to Family & Guests on the primary phone.
• Tap the user’s name and upgrade their permission level.
• Save changes and ask the user to restart the app.

Permissions are enforced immediately, but a restart ensures the app recognizes the update.

Best Practices for Managing Multiple Users

Once you’ve successfully added Eufy to a second phone, follow these best practices to keep your system secure and efficient.

1. Use Descriptive Names for Users

Instead of “User 2,” label users clearly—like “Sarah (Spouse)” or “Mike (Babysitter).” This makes it easier to manage permissions later.

2. Limit Admin Access

Only give Admin rights to people you fully trust. Most users only need Viewer or User access.

3. Regularly Review User List

Periodically check the Family & Guests section. Remove access for people who no longer need it—like a former roommate or temporary helper.

4. Enable Two-Factor Authentication (2FA)

On both accounts, enable 2FA for extra security. This requires a code from your phone when logging in from a new device.

5. Keep Devices Updated

Eufy releases firmware updates for cameras and hubs. Regular updates improve performance and fix security vulnerabilities.

6. Use Strong Passwords

Encourage all users to create strong, unique passwords for their Eufy accounts. Avoid reusing passwords from other sites.

Can You Add More Than One Second Phone?

Absolutely! Eufy allows multiple users to access the same system. You can invite as many people as needed—family members, roommates, property managers, or even employees if you’re using Eufy for business security.

Each user receives their own invitation and can have customized permissions. For example:

• Your spouse: Admin access
• Teenager: Viewer access
• House cleaner: User access (limited to certain devices)

There’s no official limit on the number of users, but performance may vary with very large groups. For most households, 5–10 users is more than sufficient.

Does Sharing Access Affect Privacy?

This is a common concern. Rest assured, Eufy prioritizes privacy:

• All data is encrypted end-to-end.
• Video is stored locally on the device or optional cloud (if subscribed).
• Users can only see devices they’ve been granted access to.
• The primary user can revoke access at any time.

However, remember that anyone with access can view live feeds and recordings. Only share with people you trust.

Alternative: Use a Shared Family Account

Some families prefer to use a single Eufy account across multiple phones. While possible, this approach has drawbacks:

• All users share the same login—less secure.
• No individual permission control.
• Activity logs are harder to track.
• Risk of accidental changes by any user.

For better security and control, we recommend using individual accounts with invitations instead.
