How to Change Your Modem Password: A Step-by-Step Guide

In today’s connected world, your modem is the gateway to the internet for every device in your home or office. While many users set up their internet and forget about their modem’s configuration, one crucial security task should never be ignored: changing your modem password.

Whether you’re securing your network from intruders, improving password strength, or simply resetting a forgotten login, updating your modem password is a smart and necessary step. In this comprehensive guide, we’ll show you exactly how to change both your modem’s admin password and Wi-Fi network password using easy-to-follow instructions.

Why You Should Change Your Modem Password

Most modems come with a default username and password like admin/admin or admin/password. These credentials are easy for hackers or unauthorized users to guess—especially if you haven’t changed them since installing the modem.

Here’s why changing your modem password matters:

• 🔐 Improved security: Prevents unauthorized access to your modem’s settings
• 👥 Prevents Wi-Fi freeloaders: Stops neighbors or strangers from using your internet
• 🧰 Prevents tampering: Keeps your network configuration and connected devices safe
• 🆕 Avoid default credentials: Protects against automated hacking tools that target known defaults

Changing both the admin password (used to log in to the modem settings) and the Wi-Fi password (used to connect to the internet) is essential.

Types of Modem Passwords

Before diving into the how-to steps, it’s important to understand the two key types of modem passwords:

1. Admin Password (Modem Login Password)

This password is used to log in to the modem’s configuration page—where you can manage settings like Wi-Fi, DHCP, firewall, and firmware updates.

• Default credentials are often printed on the modem label.
• Changing this password protects against unauthorized access.

2. Wi-Fi Network Password

This is the password you enter when connecting devices (phones, laptops, smart TVs) to your wireless network.

• Also called the pre-shared key (PSK).
• Should be changed from the default to keep your network private and secure.

Things You’ll Need

To change your modem password, gather the following:

• A device connected to your modem (via Ethernet or Wi-Fi)
• Your modem’s IP address (often 192.168.0.1 or 192.168.1.1)
• Default or current admin username and password
• A new password (see our tips below)

You can usually find the default login info and IP address on a sticker on the back or bottom of the modem.

Step-by-Step: How to Change Your Modem Admin Password

Follow these steps to change the login password used to access your modem’s settings:

Step 1: Connect to the Modem

Use a desktop, laptop, or mobile device connected to the modem’s network.

• Ethernet connection is preferred for stability.
• If using Wi-Fi, make sure you have a strong signal.

Step 2: Open a Web Browser

In the address bar, type your modem’s IP address. Common addresses include:

• 192.168.0.1
• 192.168.1.1
• 10.0.0.1 (for some ISPs like Xfinity)

Hit Enter to load the modem’s login page.

Step 3: Log In Using Admin Credentials

Enter your admin username and password. Common defaults:

• Username: admin
• Password: admin, password, or blank

💡 Tip: If you changed the password before and forgot it, skip ahead to Resetting Your Modem.

Step 4: Find the Password Settings

Once logged in, look for a section labeled:

• Admin
• System
• Security
• Management
• Settings → Password

Click the appropriate section to access the password change page.

Step 5: Change the Admin Password

Enter your current password, followed by your new password and confirmation.

Example fields:

• Current Password: admin
• New Password: MyStrongPassword2025!
• Confirm Password: MyStrongPassword2025!

Click Save, Apply, or Submit to confirm.

Step 6: Log In Again (If Prompted)

You may be logged out and asked to re-enter the new password to confirm the change.

How to Change Your Wi-Fi Network Password

This is the password people use to connect to your wireless network. To change it:

Step 1: Log In to the Modem Interface

Follow steps 1–3 above to access your modem’s web interface.

Step 2: Navigate to Wireless or Wi-Fi Settings

Look for a tab labeled:

• Wireless Settings
• Wi-Fi
• SSID/Network

There might be separate tabs for 2.4GHz and 5GHz bands.

Step 3: Locate the Network Password Field

Find the field labeled:

• Pre-Shared Key
• Passphrase
• Wi-Fi Password

Step 4: Enter a New Wi-Fi Password

Type your new password in the appropriate field. Example:

• New Password: HomeSecure2025!

Make sure to save or apply changes.

Step 5: Reconnect All Devices

All previously connected devices will be disconnected. Reconnect them using the new Wi-Fi password.

How to Reset Your Modem If You Forgot the Password

If you’re locked out of the modem interface and can’t remember the admin password, perform a hard reset.

Step 1: Locate the Reset Button

Find a small pinhole button labeled Reset on the back of the modem.

Step 2: Press and Hold for 10–30 Seconds

Use a paperclip or pin to press and hold the button until lights start flashing.

Step 3: Wait for the Modem to Reboot

This process can take 2–5 minutes. The modem will return to factory default settings.

You can now:

• Log in using default admin credentials
• Reconfigure settings including Wi-Fi and password

Tips for Creating Strong Passwords

A strong password helps prevent unauthorized access and hacking attempts. Use the following guidelines:

✅ Use a Mix of Characters

Combine uppercase, lowercase, numbers, and symbols.

Example: NetSecure#2048!

✅ Avoid Common Words

Skip obvious choices like admin123 or password.

✅ Make It Long

Aim for at least 12–16 characters.

✅ Change It Regularly

Change your admin and Wi-Fi passwords every 6–12 months.

✅ Use a Password Manager

Apps like Bitwarden, LastPass, or 1Password can help manage and store complex passwords securely.
