Best Practices in Securing Passwords for IoT Devices

In an era dominated by digital connectivity, robust password security becomes a necessity for all users. Today's digital world requires strong password security, extending beyond online accounts to a growing range of IoT devices like smart thermostats and cameras. Basic password rules apply universally, but IoT devices bring their own unique security challenges. These devices not only widen the scope of our digital footprint but also expose our physical spaces to cyber risks.

The increasing number of attacks on IoT devices highlights the need for enhanced password security strategies for these specific assets. Whether securing your email or your smart home, effective password management is key to protecting against cyber-attacks. This guide will cover essential and IoT-specific password best practices to help you enhance your overall digital and connected security. Don’t forget to check out our comprehensive guide for password security for the basic password rules.

Password Do's for IoT Devices

1. Default Passwords

Change the DefaultIoT devices often come with default usernames and passwords that are easy for attackers to guess. Always change these as soon as you set up the device.

2. Device-Specific Passwords

Unique Credentials: Given that IoT devices are often linked to control centers or even your smartphone, use different passwords for the device and the control account.

3. Complexity Matters

Strong Passwords: Even if the device seems trivial, like a lightbulb, ensure that the password is strong. Attackers can use less secure devices as entry points into your network.

4. Two-Factor Authentication (2FA)

Enable if Possible: Some advanced IoT devices may offer 2FA. Make use of this feature when available.

5. Network Segmentation

Different Network: If possible, place your IoT devices on a separate network from your main computing devices. This adds an extra layer of security in case the IoT device is compromised.

6. Periodic Updates

Change Passwords Regularly: Just like your other accounts, the passwords for IoT devices should be updated periodically.

7. Recovery Methods

Secure and Up-to-Date: Make sure that the recovery methods are not only secure but also up-to-date. If you lose access to the device, a secure recovery process is essential.

Password Don'ts for IoT Devices

1. No Defaults

  • Don't Keep Default Credentials: This can't be emphasized enough. Attackers often have lists of default credentials for various IoT devices.

2. No Shared Passwords

  • Don't Use Common Passwords: Your IoT devices should not share passwords with each other or with any of your other accounts.

3. Avoid Public Networks

  • Don't Connect to Insecure Networks: Whenever possible, don't connect your IoT devices to public or unsecured Wi-Fi networks.

4. No Open Controls

  • Don't Leave Admin Panels Open: Always logout of admin panels and control centers for IoT devices and smart appliances when you're done configuring them.

5. Ignore Security Alerts

  • Don’t Neglect Warnings: IoT devices may not have as sophisticated alert systems as other platforms, but if you do receive a security alert, take it seriously.

6. No Easy Recovery

  • Don’t Use Easy Recovery Questions: If the device allows for recovery questions, make sure they are not easily guessable or searchable.

7. Overlook Software Updates

  • Don't Ignore Updates: IoT devices often receive firmware updates that may include security patches. Make sure to apply these updates promptly.


Overall, the surge in IoT-related cyber-attacks serves as a stark reminder of the importance of robust password security for these assets. Whether it's securing your email or fortifying your smart home, effective password management remains the linchpin of defense against cyber threats.

While many of the core principles of password security remain the same, IoT devices introduce unique challenges and risks that warrant special considerations. Always read the security guidelines provided by the manufacturer and remain vigilant to protect your connected devices.
