Where HP printer credentials come from

Your HP printer has two separate sets of login information, and they come from different places. The admin password is set during initial setup — either by you or by whoever installed the printer. The username is almost always "admin" by default, though some network setups change this. If you did not set these yourself, you will need to contact whoever manages your printer or check your printer's setup documentation.

The printer's web interface — the page you reach by typing your printer's IP address into a browser — is where you use these credentials. This is different from your computer username, which you use to log into Windows or Mac. The printer does not know or care about your computer login.

If you are trying to print from your computer and the printer is asking for a password, that is usually a different problem: your computer is trying to authenticate to the printer on your network, which requires the printer's network password, not the web interface password.

Key Takeaways

  • The default username for HP printer admin access is almost always "admin," and the password is whatever was set during initial setup or left as the factory default.
  • If you do not know the password, check the printer's physical documentation, the setup card that came with it, or contact your IT department if this is a work printer.
  • You access the printer's login page by typing its IP address (usually found in Settings or Network on the printer's screen) into a web browser.
  • Resetting the printer to factory defaults will erase all custom settings and return the password to whatever HP set it to originally, but this is a last resort.
  • The printer's admin password is separate from your computer username and password — they do not need to match.

Finding the printer's IP address

Before you can reach the login page, you need to know where the printer is on your network. Most HP printers display this on their control panel. Look for a button labeled "Settings," "Network," or a gear icon, then navigate to "Network Settings" or "TCP/IP." The IP address will look like four numbers separated by periods: 192.168.1.100, for example.

If your printer does not have a touchscreen, print a network configuration page. On many HP models, you hold down the "Information" or "Settings" button until the printer beeps, then release. Check your printer's manual for the exact button combination. This page lists the IP address along with other network details.

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 — for example, http://192.168.1.100 — and press Enter. You should see the HP printer's login page.

The default username and password

The username field almost always accepts "admin" on HP printers. This is the standard across their product line. The password is where it gets tricky: HP does not set a universal default password. Instead, the password depends on when and where the printer was manufactured and what model it is.

Common factory defaults include "admin," a blank password (just press Enter), or a numeric code printed on a sticker inside the printer or on the setup documentation. Check any paperwork that came with the printer — setup guides, quick-start cards, or warranty information often list the default password. If the printer came from a business, the IT department may have set a custom password during deployment.

If you are locked out after multiple wrong attempts, the printer may temporarily disable login. Wait 15 to 30 minutes before trying again, or power-cycle the printer by unplugging it for 30 seconds.

Checking your printer's documentation

The fastest way to find credentials is to look at what came with the printer. The setup guide, quick-start card, or even the box itself sometimes lists default login information. If you bought the printer used or inherited it from someone else, search online for "[your printer model] default password" — HP publishes this information for most models on their support site.

You can also find your printer model number on the printer itself, usually on a sticker on the back or inside the access panel. Once you have the model number, visit HP's support website and search for your model. Look for "Getting Started," "Setup Guide," or "Network Configuration" documents. These often include default credentials.

What to do if you cannot find the password

If the printer belongs to your workplace, contact your IT department or whoever manages your printers. They have records of what password was set during setup. Do not attempt to reset the printer without permission — it will erase all custom settings, network configuration, and security policies your organization put in place.

If this is your personal printer and you genuinely cannot find the password, a factory reset is your last option. The process varies by model: some printers have a "Reset" button you hold for 10 seconds, others require you to navigate to Settings > Restore Defaults on the control panel. Check your model's manual for the exact steps. After a reset, the printer returns to its original factory state, and you can set a new admin password during the setup process.

Before you reset, try one more thing: check if there is a sticker on the inside of any access panel or door. HP sometimes prints default credentials on internal stickers that are straightforward to miss.

Keeping your printer password find

Once you are logged in, change the default password to something only you know. Navigate to the "Security" or "Administration" section of the web interface and look for "Change Password" or "User Accounts." Use a password that is at least 8 characters long and includes numbers or symbols — the same way you would find any other device on your network.

Do not use the same password as your computer or email. If someone gains access to your printer, you do not want them to have access to your other accounts. Also avoid writing the password on a sticky note near the printer. If you need to store it, use a password manager like Bitwarden or 1Password that encrypts it.

Printer password versus network password

If your computer is asking for a password when you try to print, that is usually the printer's network password, not the admin password. This is a separate credential that controls who can send print jobs to the printer. On Windows, this appears as a popup asking for a username and password when you first try to print.

To set or change the network password, log into the printer's web interface with the admin credentials, then look for "Network" or "Security" settings. You may see an option for "SMB Password" or "Network Authentication." This is what your computer will ask for when you print. Make sure you use the same username and password on all computers that need to print to this device.

Frequently Asked Questions

What if the printer says "authentication failed" when I try to log in?

Check that you are typing "admin" in the username field and that Caps Lock is off. Passwords are case-sensitive. If you have tried multiple times, wait 15 to 30 minutes — the printer locks you out temporarily after failed attempts. If you are still stuck, try the factory default password for your specific model by searching online for "[model number] default password."

Can I reset the password without losing my printer settings?

No. A factory reset erases everything: the password, network settings, print job history, and any custom configurations. If this is a work printer, contact IT before resetting. If it is yours, resetting is the only way to regain access if you have lost the password.

Do I need the printer password to print from my computer?

Not always. If the printer is on your home network and you set it up yourself, you usually do not need a password to print. If your computer asks for one, it is the network password, not the admin password. These are two different things. Ask whoever manages the printer what the network password is.

Where is the IP address shown on the printer screen?

Look in Settings or Network Settings on the printer's control panel or touchscreen. It will be labeled "IP Address" or "IPv4 Address" and look like four numbers separated by periods. If your printer does not have a screen, print a network configuration page by holding the Information or Settings button until the printer beeps.

Is it safe to leave the default password on my printer?

No. Anyone on your network can access the printer's settings and potentially see documents you have printed. Change the password to something unique as soon as you log in. Use at least 8 characters and include numbers or symbols.
