Many users face a situation where they urgently need to print a document or transfer a photo to a TV, but the system asks access codeA common question is: what's the Wi-Fi Direct password if no one has changed it? The answer depends on the device manufacturer and model, as there's no single, universal standard for all gadgets.
In most cases, factory settings assume the use of standard combinations or the generation of a random set of characters when the function is first enabled. Understanding the logic behind the protocol Wi-Fi Direct will help you quickly find the data you need in the menu of your device, whether it is a modern one Android- smartphone or office HP LaserJet.
Connection security in this mode is critical, as you're essentially creating an access point that others can connect to. In this article, we'll cover all the nuances: from finding forgotten data in the printer interface to forcibly changing the router key. MikroTik And TP-Link.
Factory default passwords and how to find them
The first thing to do when searching for lost data is to consult the documentation or label on the case. Electronics manufacturers often use predictable schemes for initial setup. For example, for many models HP And Canon the standard value is 12345678 or 00000000.
However, you shouldn't rely on versatility. Modern devices, especially televisions Samsung And LG, can generate a unique PIN code dynamically each time the function is launched. This code is displayed on the TV screen while waiting for a new signal source to connect.
- 🔍 Check the sticker on the back of the device; it often contains a PIN or WPS code.
- 📄 Check your user manual, under the "Wireless Networks" or "Direct" section.
- 🖨️ On printers, print a network configuration report through the maintenance menu.
- 📱 On smartphones, the code may be sent in a notification when a connection request is made.
If simple combinations don't work, your device likely has WPA2 security enabled with a random key. In this case, resetting the network settings or printing a configuration sheet will help.
How to find the password on HP and Canon printers
Office equipment requires special attention, as it often lacks a full-screen display for data entry. To find out the Wi-Fi Direct password on a printer HP, you need to print an information sheet. This can be done through the control panel: find the wireless icon or the "Reports" menu.
On the printed sheet, look for the line Wi-Fi Direct PasswordIf there's a dash or "Disabled," it means the feature is disabled or no password has been set. To activate protection, go to the menu Network → Wi-Fi Direct → Settings and set your value.
⚠️ Please note: After resetting your network settings to factory defaults (Cold Reset), the password will return to the default one indicated on the sticker, but all your custom IP address settings will be lost.
For devices Canon the procedure is similar, but the menu may be called Device SettingsIn some models of the series Pixma And MG The code is displayed on a small monochrome display when you press the direct print button from your mobile device.

Wi-Fi Direct settings on Android and Samsung
In the ecosystem Android The situation is slightly different. A static password is rarely used to enter a group; a pop-up confirmation method (P2P Invitation) is more common. However, if you create a group, the system may prompt you to establish security.
To find or change settings, go to Settings → Connections → Wi-FiIn the upper right corner, click the three dots or the "More" button, then select Wi-Fi Direct. Available devices and the status of the current connection are displayed here.
On smartphones Samsung with shell One UI The path may vary. Sometimes you need to enable developer mode or use an app. Smart View for broadcasting where a password request occurs when attempting to mirror the screen to a TV.
Access control on TP-Link and MikroTik routers
If you're setting up a Wi-Fi Direct access point on a router, you have full control over the encryption key. In the interface TP-Link go to the section Wireless → Wireless SettingsThis is where the question is asked. Pre-Shared Key, which will be used by customers.
For advanced users MikroTik Configuration is done via WinBox or terminal. Command /interface wifi p2p-group allows you to create a group where the parameter passphrase will be the password you're looking for. Without entering it correctly, connection is impossible.
| Device | Settings menu | Standard key | Encryption type |
|---|---|---|---|
| HP Printer | Network / Reports | 12345678 | WPA2 |
| Samsung TV | General / Network | Dynamic | WPA2-PSK |
| TP-Link Router | Wireless Settings | No password* | WPA/WPA2 |
| Xiaomi Phone | Wi-Fi / Direct | Confirmation request | WPA2 |
It is important to understand the difference between a Wi-Fi router password and a key. DirectThese are different networks, even if the names (SSIDs) are similar. Changing the password on the main router will not change the key for direct connection between the devices.
Safety issues and risks of use
Using default passwords carries serious risks. Protocol Wi-Fi Direct creates a direct connection between devices, bypassing the access point. If an attacker knows the standard code (for example, 12345678), he can access your printer or files on your smartphone.
Leaving print ports open in public places is especially dangerous. Hackers can exploit protocol vulnerabilities to inject malicious code or intercept data you send to print. Always reset your printer to factory defaults immediately after purchase.
What is the danger of WPS in Direct mode?
WPS (Wi-Fi Protected Setup) is often used for quick connections, but it's vulnerable to brute-force attacks. If the WPS indicator on your router or printer is lit, it's best to disable this feature in the security settings.
What to do if your password is incorrect or forgotten
The most common problem is that the device displays "Incorrect Password" even though you're entering the correct characters. First, check your keyboard layout and letter case. Systems are sensitive to Case Sensitive (the difference between uppercase and lowercase letters).
If you don't remember the code exactly, the only reliable way is to reset the network settings. On printers, this is often done by holding the wireless button for 10-15 seconds. On routers, the Reset on the body.
⚠️ Please note: Resetting Wi-Fi Direct settings on corporate printers may require reconfiguring IP addresses and drivers on user computers.
After the reset, your device will return to its factory settings, and you can set a new, complex password that's easy to remember. We recommend using a combination of letters and numbers at least 8 characters long.
Frequently Asked Questions (FAQ)
Is it possible to connect to Wi-Fi Direct without a password?
Yes, if security mode is disabled or set to "Open" in the device settings (printer or TV). However, this is highly discouraged, as anyone within range will be able to connect to your device.
Why can't my phone see the printer in Wi-Fi Direct mode?
Make sure Direct mode is enabled on the printer, not just Wi-Fi. Also, check that your phone isn't connected to a different Wi-Fi network, which could be blocking local device discovery.
Where can I find a QR code for quick connection?
On modern models HP And Canon The QR code is printed on the information sheet along with the password. By scanning it with your smartphone camera, you can automatically connect without manually entering any characters.
Does a Wi-Fi Direct password affect internet speed?
No, the password itself doesn't affect speed. However, using WPA2 encryption may slightly increase the processor load on older devices, which could theoretically reduce the transfer speed of large files, but in everyday use, this isn't noticeable.
