Wi-Fi Password Generator
Create a strong, random password for your Wi-Fi network. A good Wi-Fi password is the single most important barrier between your network and unauthorised access.

What Makes a Strong Wi-Fi Password?
A good Wi-Fi password needs to be long enough that brute-force attacks take impractically long, and random enough that dictionary attacks fail. WPA2 and WPA3 support passwords up to 63 characters. Here is what actually matters:
- At least 12 characters, 16 or more is significantly better
- Mix of uppercase, lowercase, numbers, and symbols
- No recognisable words, names, or patterns
- Not related to your address, phone number, or birthdate
- Different from every other password you use
- Stored in a password manager, not written on a sticky note
WPA3 makes brute-force attacks significantly harder than WPA2. If your router supports WPA3, enable it in the wireless security settings - even a somewhat shorter password is much more resistant to offline cracking attempts.
How to Change Your Wi-Fi Password
Use the generator above to create a Wi-Fi password with 16+ characters mixing letters, numbers, and symbols.
Open your router admin panel at 192.168.1.1 or 192.168.0.1 and navigate to the Wireless or Wi-Fi settings section.
Paste the generated password in the Wi-Fi Password or WPA Key field. Ensure WPA2 or WPA3 encryption is selected.
Save the settings. The router will disconnect all Wi-Fi devices. Reconnect each device with the new password.
What Actually Makes a Wi-Fi Password Strong
Wi-Fi cracking isn't someone guessing at your login screen; an attacker captures the WPA2 handshake out of the air and then throws a GPU at it offline, billions of guesses per second, no lockouts, no trace. Against that, length beats cleverness every single time. "Tr0ub4dor!" style substitutions add almost nothing, cracking tools try those mutations automatically, while every added character multiplies the work. A 16+ character passphrase of random words ("plum-orbit-thunder-cactus") is both stronger and typeable on a TV remote, which matters more than people admit.
Things that genuinely don't help: hiding the SSID (devices then broadcast it everywhere they go), MAC filtering (covered honestly here), and changing the password on a schedule (you'll trend toward weaker, more memorable choices). Things that do: WPA3 or at least WPA2-AES, WPS off, and a genuinely long passphrase set once and shared via QR code instead of shouted across the room.
After You Generate One
Changing the Wi-Fi password logs out every device in the house, so batch the pain: do it once, properly, and reconnect things in order of complaint volume. Phones and laptops take seconds. The annoying stragglers are printers, smart plugs and anything configured through a companion app years ago, some of those need their setup flow re-run from scratch, and it's precisely why people postpone this chore for years. Budget twenty minutes, not two.
Store the new password where future-you will look: a password manager entry named after the network, plus the QR-share feature both iOS and Android build in (Settings → Wi-Fi → share) for guests. And while you're logged into the router anyway, the full walkthrough covers the couple of settings worth checking in the same visit.
