Encryption credentials have expired

Every time you want to print on your Mac, do you see the annoying notice “Encryption credentials have expired”? It’s not just you! After installing a fresh macOS update, many Mac owners discover themselves trapped in this printing hell. Nothing is more annoying, in our opinion than trying to print a crucial document and encountering difficulties. The good news is that it’s frequently simpler to repair this annoying problem than you would imagine. You may bring your printer back to life by identifying the underlying issue and using some astute technological know-how.

Let’s speak about some solutions now, before you think about investing in a new printer or placing a panicked call to tech support. When the security features of your printer conflict with your most recent version of macOS, the error “Encryption credentials have expired” frequently appears. But don’t worry! You can immediately put some simple changes into action to get your printer working again. We’ll walk you through each step of the process to permanently eliminate this problem, from reinstalling your printer using alternative protocols to clearing the network settings on your printer.

Common Causes of the Encryption Credentials Have Expired Issue

You might be puzzled about why your Mac suddenly says your “Encryption credentials have expired,” essentially holding your printer hostage. Usually, this hiccup arises after you’ve updated your macOS. Believe it or not, new macOS versions can be a bit finicky when it comes to trusting old encryption credentials. So, the moment you hit that update button, you could be stepping into murky waters. Incompatibility between the newest macOS and your printer’s older drivers can often be the root cause of this vexing issue.

Another common culprit is the natural expiration of credentials within the printer software itself. Just like your favorite snack, these credentials come with a “best before” date. When an AirPrint driver is installed and set as Secure AirPrint, the clock starts ticking, and those credentials will eventually expire, triggering the dreaded “Encryption credentials have expired” alert. Keeping an eye on these expiration timelines can spare you a headache down the road. Armed with this knowledge, you’ll be better equipped to navigate the labyrinth of printer errors and get back to smooth sailing—or in this case, smooth printing.

How to Avoid Encryption Credentials Have Expired Issue

To avoid the “Encryption credentials have expired” error on your Mac, especially with your printer, it’s important to keep both your printer’s firmware and macOS up to date. Updates often fix compatibility and security issues. Try to check for updates monthly or enable automatic updates if possible. This ensures your system’s encryption credentials stay current and reduces the chance of encountering this error.

Also, regularly check your printer’s settings, including its encryption credentials. Most printers have a web server you can access with your browser using the printer’s IP address. Make it a habit to log in and check the status of your encryption settings. If these credentials are about to expire, refresh or change them. Keep an eye out for any alerts or notifications concerning expiration credentials from your printer software. This proactive approach helps prevent the frustrating “Encryption credentials have expired” message.

These preventative strategies help avoid errors such as “Encryption credentials have expired” as well. They are reliable best practices for guaranteeing a seamless and trouble-free Mac printing experience. You may invest in fewer interruptions and increased productivity by including these actions in your digital routine regularly.

How to fix the Encryption credentials have expired

1. Reinstall the Printer Using the AirPrint Protocol

Experiencing the “Encryption credentials have expired” alert when attempting to print from your Mac? One effective solution is to reconfigure your printer through the AirPrint protocol.

Detailed Steps to Reconfigure Your Printer:

  1. Navigate to your Mac’s desktop and click on the Apple Menu in the top-left corner. From the dropdown, select ‘System Preferences‘.
  2. Within System Preferences, look for and click on the ‘Printers & Scanners‘ icon.
  3. Once in the ‘Printers & Scanners‘ window, you’ll see a list of printers. Scroll through to find and highlight the printer that’s causing you issues.
  4. Next to the list, you’ll notice a ‘Minus(-) button. Click on it to remove the printer from your Mac. A prompt may appear asking you to confirm; click on ‘Delete Printer‘.
  5. Navigate to your Mac’s ‘/Library/Printers‘ folder and locate your printer’s folder. Drag it to the Trash. Empty the Trash folder afterward.
  6. Shut down your Mac and unplug your printer for a full reset.
  7. Once you’ve turned both your Mac and your printer back on, go back to ‘System Preferences‘ and click on ‘Printers & Scanners‘ again.
  8. This time, click on the ‘Plus‘ (+) button to add a new printer. However, when prompted to choose a driver, select ‘AirPrint‘ instead of ‘Secure AirPrint‘.

By following these comprehensive steps, you’ll have successfully reconfigured your printer using the AirPrint protocol, which should eliminate the encryption credentials issue you were facing.

2. Set Up the Printer Again Using the LPD Protocol Method

If you’re facing persistent issues where your Mac indicates that your printer’s “Encryption Credentials Have Expired,” a potential resolution might be to set up your printer once more, but this time by employing the LPD (Line Printer Daemon) protocol. This approach is particularly useful for those who have older printer models or have previously used the AirPrint protocol and are not getting the desired results.

Step-by-Step Guide:

  1. Locate and click on the ‘Applications‘ folder, then find and select ‘Utilities.’
  2. Open the ‘Printer Setup Utility‘ to begin the process of adding a new printer.
  3. Click on the ‘+‘ symbol usually located near the bottom of the window. This will allow you to add a new printer to your Mac system.
  4. Navigate to the ‘IP’ tab within the printer setup. Here, you’ll find a drop-down menu under ‘Protocol.’ Select ‘Line Printer Daemon (LPD)‘ from the list.
  5. In the designated field, enter your printer’s unique IP address. This address is generally found within the settings or documentation that came with your printer.
  6. Give your printer a name that you can easily recognize. After naming it, click the ‘Add‘ button to finalize the setup.

By setting up your printer using the LPD protocol, you might effectively bypass the “Encryption Credentials Have Expired” error, making your device functional once again. This can be a more compatible solution, especially if you have an older printer model or if the AirPrint protocol hasn’t worked for you.

3. Revitalize Your Printer’s Network Settings

If the issue of “Encryption Credentials Have Expired” continues to plague your printing experience, you may want to consider reconfiguring your printer’s network settings.

  1. Unplug your Wi-Fi router from the power source and allow it to remain off for the time being.
  2. Turn off your printer and switch it back on. This refreshes its internal systems and prepares it for the subsequent steps.
  3. Navigate to the control panel on your printer’s display screen.
  4. Look for the “Setup” option within the control panel and select it.
  5. Within the setup menu, locate the “Network Setup” option and click on it.
  6. Here, you’ll find an option that says “Restore Network Settings” or something similar. Choose this option to reset all network-related configurations to their default settings.
  7. Turn off your printer after the network settings have been restored to defaults.

4. Generate Your Own Self-Signed Certificate

If you’re still facing the issue where your Mac states that your printer’s “Encryption Credentials Have Expired,” you might want to consider creating a fresh self-signed certificate. This can be done through your printer’s Embedded Web Server (EWS), which provides an interface to control various printer settings, including security features like certificates.

Steps for Generating a New Self-Signed Certificate:

  1. Usually, this can be found on your printer’s control panel, or you can print a network configuration page directly from the printer to find the IP address.
  2. Once you have your printer’s IP address, input it into the address bar of a web browser and hit Enter. This will take you to the Embedded Web Server (EWS) page for your printer.
  3. On the EWS page, find and click on the ‘Network‘ tab to access the network settings.
  4. Here you will see an option for ‘Advanced Settings‘. Click on it. If your printer model doesn’t display ‘Advanced Settings,’ you can proceed directly to the next step.
  5. In the ‘Advanced Settings‘ section, locate and click on ‘Certificates,’ followed by clicking the ‘Configure‘ button.
  6. You’ll see an option that says ‘Create a New Self-Signed Certificate.’ Click on this option to commence the certificate creation process.
  7. Click on ‘Finish‘ and wait for the printer to generate your new certificate. This may take a few minutes, and you might need to reboot your printer to complete the process.

After these steps, check to see if the issue with the “Encryption Credentials Have Expired” warning has been resolved. If this method worked for you, it would be a more secure way to manage your printer settings. It also negates the need to rely on potentially outdated or expired credentials that may have been causing the error message in the first place.
