Check the printer's default password first

Most HP printers ship with a default password printed on a label inside the machine or in the quick-start guide that came in the box. Open the printer's access panel or flip through the physical documentation — the label usually shows both a username (often "admin") and a password (often "admin" or a string of numbers). This default password works for the printer's web interface, which you reach by typing the printer's IP address into a browser.

If you still have the original documentation, that is the fastest place to look. If the box is long gone, the same information is usually in the printer's settings menu. Press the menu or settings button on the printer's control panel, navigate to Network Settings or Device Information, and look for the IP address. Write that address down — you will need it next.

Key Takeaways

  • The default password is usually "admin" or printed on a label inside the printer or in the quick-start guide.
  • You can find your printer's IP address in the Network Settings menu on the printer's control panel or by printing a network configuration page.
  • Type the IP address into a web browser to reach the printer's settings page, where you log in with the default username and password.
  • If you changed the password and forgot it, you may need to perform a factory reset, which erases all custom settings and returns the printer to its original state.

Find the IP address on the printer itself

To access your printer's web interface and log in, you first need its IP address. On most HP printers, you can find this without a computer. Press the menu or home button on the printer's touchscreen or control panel, then look for Network Settings, Network Configuration, or TCP/IP Settings. The IP address appears as four groups of numbers separated by periods, like 192.168.1.100.

If your printer does not have a touchscreen, look for a button labeled Information or Settings. Some HP printers print a network configuration page when you hold down a specific button — check the manual or the printer's label for which button. Once you have the IP address, open any web browser on a computer connected to the same network, type the address into the address bar, and press Enter.

Log in to the printer's web interface

When you type the IP address into your browser, you should see a login page. Enter "admin" in the username field and "admin" (or the default password from your documentation) in the password field. If those do not work, try leaving the username blank and entering only the password, or try "admin" with a blank password. HP printers vary in their defaults, so you may need to try a few combinations.

Once you log in, you reach the printer's settings page. From here you can change the password, configure wireless settings, check ink levels, and manage print jobs. The exact layout depends on your printer model, but most HP printers organize settings into tabs or a menu on the left side of the page.

Reset the printer if you cannot remember a changed password

If you changed the password yourself and have forgotten it, you will need to perform a factory reset. This erases all custom settings — including the password you set — and returns the printer to its original default state. The method varies by model, but most HP printers reset when you hold down the power button for 10 to 15 seconds while the printer is on, or by navigating to Settings > Restore Defaults on the control panel.

Some models require you to hold down a specific combination of buttons. Check your printer's model number (usually on the back or bottom) and search for "[your model number] factory reset" to find the exact steps. After the reset completes, the printer will use the default password again, and you can log in with "admin" and "admin" or the password printed on the label inside the machine.

Locate the password in HP's online support resources

If you cannot find the documentation or the label inside your printer, HP's support website has default passwords for most models. Go to support.hp.com, search for your printer model number, and look for the user manual or quick-start guide in PDF format. The default credentials are usually listed in the network setup section or in a troubleshooting chapter.

You can also search "[your HP printer model] default password" in any search engine — many support forums and tech sites have compiled these defaults by model. Write down the model number from your printer (it is usually on the front, back, or inside the access panel) before you search, because HP makes hundreds of models and the password can vary.

Understand what the password protects

The HP printer password protects access to the printer's web interface and settings menu, not the printing function itself. Anyone on your network can still send print jobs to the printer without knowing the password. The password prevents someone from changing network settings, installing firmware updates, or viewing print history and stored documents.

If your printer is on a home network, this is usually not a major security concern. If it is in an office or on a shared network, changing the default password to something unique is a good practice. Once you log in with the default password, most HP printers let you create a new password in the Security or Administration settings section of the web interface.

Frequently Asked Questions

What if the default password does not work?

Try leaving the username blank and entering only the password, or try "admin" with a blank password field. If neither works, the password may have been changed by someone else. Your next step is a factory reset, which returns the printer to its original default state and erases any custom password that was set.

Can I print without knowing the password?

Yes. The password only protects access to the printer's settings and web interface. Anyone on your network can send print jobs to the printer without entering a password. You only need the password if you want to change network settings, update firmware, or access the printer's administration menu.

Where is the model number on my HP printer?

The model number is usually printed on a label on the back, bottom, or inside the access panel of the printer. It often starts with "HP" followed by letters and numbers, like "HP LaserJet Pro M404n". You need this number to find the correct default password or manual for your specific printer.

Will a factory reset erase my documents or print history?

A factory reset erases all custom settings, including the password, network configuration, and stored documents on the printer's hard drive. It does not affect documents on your computer. After the reset, the printer returns to its original default state and you can set it up again from scratch.

Can I change the password after I log in?

Yes. Once you log in to the web interface with the default password, look for a Security, Administration, or Settings section where you can create a new password. Most HP printers let you set a custom password to replace the default one, which is recommended if the printer is on a shared or office network.
