Frequently Asked Questions
A default Wi‑Fi password is the pre-configured wireless key that comes with your ISP-provided router. It's usually printed on a sticker on the bottom or back of the device, and is often derived from the router's MAC address, SSID, or serial number using a proprietary algorithm specific to each manufacturer.
Many ISPs use predictable algorithms to generate default Wi‑Fi passwords. For example, a Thomson router might derive its WPA key from the last 6 hexadecimal characters of its SSID, while a Huawei HG router might use its MAC address. Our tool implements these publicly-known algorithms to reconstruct the default password when you provide the SSID, MAC address, or serial number.
We support 20+ major ISP router brands including Thomson/Technicolor, FASTWEB, SKY UK, BT Home Hub, Huawei HG, Arris, Netgear, D-Link, Zyxel, TP-Link, Telsey, UPC/Compal, Movistar, Vodafone, ATT U-verse, Spectrum/Charter, Xfinity/Comcast, WLAN-XXXX (Telekom), Orange/EE BrightBox, and Cisco EPC. More are being added regularly.
Common scenarios include: the sticker on your router has faded or been removed, you've reset your router and can't find the documentation, you're helping a friend or family member regain access, or you're a technician setting up equipment. In all cases, you should change the default password after regaining access for security.
The default SSID is usually broadcast by your router — just scan for Wi‑Fi networks on your phone or computer. The MAC address is often printed on the router's sticker (look for "MAC," "WAN MAC," or "CM MAC"). You can also find it in your device's Wi‑Fi settings under network details. Some routers have the MAC on the box they came in.
The algorithms implemented here are based on publicly-available research and known patterns. However, ISPs occasionally change their algorithms or use different ones for different hardware revisions. If the generated password doesn't work, double-check your input values, verify the ISP/model, or try the automatic detection mode. Results are best-effort estimates.
Absolutely yes. Default passwords are a major security risk because they can be easily guessed or calculated. Anyone with basic knowledge can potentially access your network. Always change both your Wi‑Fi password and router admin password to strong, unique values as soon as you set up your device.
The encryption protocol (WPA/WPA2/WPA3) is separate from the password itself. Older routers typically use WPA or WPA2 with a default password derived from device identifiers. Newer routers increasingly use WPA3. The password generation algorithm is generally independent of the encryption protocol — the same calculated password would work regardless of whether the router uses WPA2 or WPA3.
