Hi @Adel0311,

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

I understand your printer is asking for a password to connect.

Could you also share the image of the screen where the password is prompted for better understanding?

In the mean time you may follow the steps below if you are trying to connect the printer to wireless network.

Restore the printer to the default network settings, and then use HP Smart to connect the printer to your Wi-Fi network.

Use the Cancel and Wireless buttons to restore Wi-Fi setup mode.

Press the Cancel button to ready the printer.

Press and hold the Wireless button and Cancel button simultaneously until the Power button blinks.

Note:

Your control panel might look different than the following example, but the steps are the same.

Wait 60 seconds until the Wireless light blinks blue.

Within two hours, return to the app or software to find and add your printer and complete the setup.

Step 2:

Uninstall and re-install the HP Smart app on your computer/mobile device.

Place the printer and the computer or mobile device near the Wi-Fi router.

Turn on Wi-Fi on your computer or mobile device and connect to your network. If the computer is connected to the network with an Ethernet cable, temporarily disconnect the cable and use the Wi-Fi connection during the setup.

Enable Bluetooth on the computer or mobile device so that HP Smart can detect the printer during the setup.

After installing HP Smart for iOS and Android, enable the mobile device location service and allow the app to use your location to detect the printer and offer solutions during setup.

Download the HP Smart app from 123.hp.com (Android, Apple iOS, iPadOS).

In HP Smart, click Add Printer or the plus sign to search for the printer, and then follow the instructions to complete the setup.

Let me know if this helps.

If this solution hit the spot, please come back and click "Accepted Solution" to help others find the answer. And if you'd like to say thanks, select "Yes" on the bottom left of the public post, as that would make our day! 

Take care, and have an amazing day!
