Generate a long, random Wi-Fi key using letters and numbers — strong against guessing but still practical to read aloud and type on a phone or games console. Increase the length for extra security.
Router defaults are often weak or printed on a sticker anyone can photograph. A long random key is the simplest way to lock your network down. This tool leaves symbols off by default, since many devices make them awkward to enter, and relies on length for strength instead.
It runs entirely in your browser, so the key is never sent anywhere. Set it once in your router settings and share it with a QR code if your phone supports it.
Frequently asked questions
How long should a Wi-Fi password be?
At least 16 characters. Length is what defends against guessing, and you only type it occasionally per device.
Why no symbols by default?
Symbols can be fiddly to enter on TVs, consoles, and smart devices; a longer letters-and-numbers key is just as strong and far easier to type.
Is it safe to generate my real key here?
Yes — it is created locally in your browser and never transmitted or stored.
