Many people are familiar with the situation when friends are coming over or you need to connect a new smart device but you don't remember the Wi-Fi password. Often, at this point, the "Remove" button comes to the rescue. WPS, allowing you to connect without entering long characters, but what if a numeric code is required? In this article, we'll explore where to find the standard PIN, how to change it to a more complex one, and whether this technology is even worth trusting in today's world.
Many users confuse the password for the wireless network itself and a special one. PIN code, used by the WPS protocol to authorize devices. Understanding the difference between these access keys is critical for properly configuring a home router. We'll take a detailed look at the algorithms used by manufacturers to generate these codes and explain why brute-forcing passwords is not only time-consuming but also potentially dangerous to your digital security.
There are several legal ways to find out or restore access without resorting to complex hacking tools. Below, we'll describe how to find the factory data on the sticker, how to generate a new random code via the web interface, and what precautions to take to prevent neighbors from exploiting your equipment's vulnerability.
What is WPS and why is a PIN needed?
Technology Wi-Fi Protected Setup was developed to simplify connecting devices to a wireless network without having to manually enter a complex password. The core element of this system is an 8-digit numeric code that the router verifies during a pairing attempt. This mechanism is convenient for printers, televisions, and other devices where entering characters using a remote control is difficult.
However, convenience often comes at the cost of security, as verification algorithm The PIN code has known vulnerabilities. Attackers can use brute-force programs to try combinations, as the code is checked not on all eight digits at once, but on two separate parts. Therefore, understanding how this protocol works helps better protect your network from unauthorized access.
It's important to understand that the WPS PIN and the Wi-Fi password (WPA2/WPA3 encryption key) are different things, although they are linked in the router settings. If you reset your wireless network settings, the WPS PIN may remain the same if it's statically set, or it may change if random generation is configured. Distinguishing these concepts is essential for properly diagnosing connection issues.
⚠️ Note: The WPS protocol is considered an outdated security standard. Many modern routers have this feature disabled by default or hide the PIN entry option from the interface.
Where can I find the factory WPS password on my router?
The easiest and most reliable way to find out the PIN code is to look at the sticker located on the bottom or back of the device. Manufacturers often indicate factory data there, including Network SSID, Wi-Fi password, and WPS PIN. This code is typically 8 digits long and may be labeled "PIN Code," "WPS PIN," or "Key."
If the sticker is worn off or missing, information can be found in the documentation that came with the equipment. The user manual often provides a unique code for a specific model or even a specific device. Also, some manufacturers, such as TP-Link or Asus, duplicate this information on a separate quick setup card.
If the physical storage media is lost, it's worth checking the router's web interface. By accessing the settings via a browser, you can see the current WPS status and the current PIN in the corresponding section. To access this data, you'll need to enter the administrator username and password, which are often also found on the same factory sticker.
How to generate a new PIN code through the interface
If you don't like the default code or suspect it may have been compromised, you can change it in your router settings. To do this, log in to the control panel, usually accessible at 192.168.0.1 or 192.168.1.1In the menu, find the section responsible for wireless network or security and select the subsection WPS.
In most modern interfaces, for example in routers Keenetic or MikroTik, there's a function for generating a new random PIN. Clicking the "Generate" or "New PIN" button will create a new combination of numbers, which you'll need to remember or write down. After this, all devices previously connected via WPS may require re-authorization.
Some models allow you not only to change the code but also to completely disable the PIN entry function, leaving only the push-button connection active. This is a compromise that preserves the convenience of a quick connection but prevents remote guessing by intruders. This mode is recommended if you require WPS.

Table of standard PIN codes by manufacturer
Many users are looking for universal combinations that work on routers of specific brands. While unique codes are generated individually, there are factory algorithms and default values that are used by default until initial setup or reset. Below is a table with the values and generation features for popular manufacturers.
| Manufacturer | PIN code type | Where to find | Peculiarities |
|---|---|---|---|
| TP-Link | Random (8 digits) | Sticker on the bottom | Changes when reset |
| Asus | Last 8 digits of MAC | Sticker / Interface | Often static |
| D-Link | Factory (8 digits) | Sticker / Documentation | Can be changed manually |
| Zyxel | Random | Sticker on the body | High entropy |
It's worth noting that relying on standard or predictable PIN codes significantly reduces security. If your router model generates a code based on the MAC address or serial number using a known algorithm, your network is vulnerable to automatic key recovery. In such cases, The only reliable protection is to completely abandon the use of WPS in favor of entering a WPA2/WPA3 password.
Why you shouldn't try to guess your password
Attempting to brute-force a WPS PIN is not only a difficult technical task but also illegal if it's on someone else's network. Modern routers have built-in security mechanisms, such as locking after several unsuccessful attempts, making manual brute-force attacks virtually impossible. The time spent on such experiments is rarely worth the reward.
Additionally, using specialized WPS hacking software such as Reaver or Bully, requires a special wireless adapter and in-depth knowledge of network security. Even with the equipment, success isn't guaranteed, as manufacturers constantly release firmware updates to patch known protocol vulnerabilities.
Instead of searching for ways to hack or brute-force your network, it's much more effective to secure your own network. Use strong passwords, regularly update your router firmware, and disable unused features. If you've forgotten your network password, it's easier to reset it using the reset button. Reset and reconfigure the device rather than try to restore access through vulnerabilities.
⚠️ Warning: Using password-guessing tools on networks not owned by you may violate computer security laws. Only use tools within your own network.
Alternative ways to connect without a password
If you don't like the WPS feature or it doesn't work, there are other convenient ways to connect devices. Many modern routers and smartphones support the technology. QR codesSimply generate a code with your network information in your phone or router settings, scan it with the camera of another device, and the connection will occur automatically.
Another option is to use technology WPS Push Button (PBC). In this case, you don't need to know any numbers or codes. Simply press the physical button on the router and simultaneously activate the WPS search on the connecting device (for example, in the Wi-Fi menu on Android or Windows). The router and client will exchange keys automatically within 2 minutes.
For devices without a screen, such as smart light bulbs or plugs, manufacturers often use Bluetooth pairing mode or direct access point (AP mode). The device creates its own temporary network, you connect to it with your phone, transfer data from the main Wi-Fi network, and the gadget joins the general network. This is safer and more secure than using a vulnerable PIN code.
What to do if the WPS button does not work?
If the button doesn't respond, the function may be disabled in the router's software. Go to the settings and check if the WPS module is enabled. The button may also be combined with the Wi-Fi or Reset button. Try pressing it briefly (1 second) or holding it longer (3-5 seconds) to see how the indicators react.
FAQ: Frequently Asked Questions
Is it possible to find out the WPS PIN code if I forgot it and the sticker was erased?
Yes, if you have administrator access to the router's web interface. Go to the wireless network or WPS section; the current PIN code will be displayed. If the interface doesn't display the code and only allows you to change it, try a factory reset. This will reset the code to the factory default on the sticker (if it's legible) or to the default for this model.
Is it safe to keep WPS enabled all the time?
No, this is not recommended. The WPS protocol has fundamental vulnerabilities in its PIN verification design. Even if you set a strong code, the verification mechanism itself allows brute-force attacks on the network. It's best to enable this feature only when connecting a new device, and then disable it in the router settings.
What is the difference between a WPS PIN and a Wi-Fi password?
The Wi-Fi password (WPA2 key) is used to encrypt all traffic and protect data. The WPS PIN is simply the key for the initial handshake, allowing the device to automatically obtain the network password. These are two different authentication mechanisms, although they lead to the same result—internet access.
Is it possible to change the WPS PIN on any router?
Not all devices. Budget models or older firmware versions may have a hard-coded PIN that can't be changed through the interface. In such cases, the only way to change the code is to completely reflash the device or replace it with a more modern model with flexible security settings.
⚠️ Note: Router interfaces and settings locations may vary depending on the model and firmware version. If you don't see the options described, please refer to the official documentation from your device manufacturer.
