How many passwords do you have? Are they all different? A secure password helps to protect your information. These tips will help you create and manage more secure passwords.

Common types of passwords

Types	Password Details	Manage
PPP	The PPP username/password is what the modem presents to your ISP to gain access to the internet. This information is automatically programmed into your CenturyLink supported modem during the initial setup. If the automated process fails, or you are using a non-standard equipment, you may need the PPP username/password to program your equipment manually. If you have an ISP other than CenturyLink, contact them for details on connecting to the internet.	Chat with tech support
Admin.	The modem's admin username/password is used to restrict access to your modem settings. The modem GUI (located at http://192.168.0.1) gives you access to utilities, tools, and settings like wireless, port forwarding, firewall, and more.	Manage
Wireless	The wireless username/password (a.k.a. SSID or passphrase) on your modem is used to restrict access to your modem's ability to provide a wireless internet connection.	Manage
Email	An email password is used to restrict access to your email.	Manage
My CenturyLink	My CenturyLink is your online account access to view and pay your bill and make changes to your CenturyLink account and features.	Manage

Safe passwords

The Federal Communications Commission (FCC) provides these recommendations on creating secure passwords:

Don't use the same password for multiple accounts, especially for the most sensitive ones, such as bank accounts, credit cards, legal or tax records and files containing medical information. Otherwise, someone with access to one of your accounts may end up with access to many others.
Don't have your web browser remember passwords and input them for you, particularly for your most important financial, legal and medical accounts. If an unauthorized person gains access to your computer or smartphone, they could access any account that your browser automatically logs into.
Don't use passwords that can be easily guessed, such as common words and birthdays of family members. Instead, use a combination of letters, numbers, and symbols. The longer and stronger the password, the safer your information.

Operating system

Make sure your device's operating system, browser, plug-ins, and programs are up-to-date. Here are some tips:

Operating system: Typically, unless you've changed your device's settings, it will automatically prompt you when there are updates to install.
Programs and apps: Check with the manufacturer or app store to look for updates.
Browsers and plug-ins: Try using a website like whatismybrowser.com to see if your browser and plug-ins are up-to-date.

Security software

CenturyLink takes your internet safety seriously. We offer security software at no extra charge to our residential internet customers. Some customers also have Secure WiFi, providing security for the entire home network directly from the modem.

Wireless network

Wireless networks can be vulnerable to hackers or malicious software (such as worms). Wireless networks use radio waves that can go beyond the boundaries of your home or business. If you don't secure your network, people with computers nearby may be able to access information on your computers and use your internet connection to perform illegal activities. Set up a custom security key on your wireless network (WPA is recomended), to help protect it from unauthorized access.

Internet users are constantly being offered free software. Remember that behind every website or email campaign is a real individual or business attempting to generate revenue. Be cautious when considering installing “free software.”

Downloading freeware

Legitimate software can be modified to house malware and made available for download on third party sites. The safest way to obtain software is to download it directly from the manufacturer.

Downloading trial software

Sometimes companies offer "trial software" or beta versions of the software that may expire after a set time or be limited in functionality. Some of this is legitimate, but some will deliver malware or extra items that the user did not agree to. Do research on the software package online to see what others who have tried it are saying about it. There are many online sites where users report malicious software packages.

In additon to keeping your email account secure with a strong password, stay aware of common email scams such as:
