Free Wi-Fi Password Generator
Create a strong, WPA2/WPA3-safe Wi-Fi password that is long enough to resist brute-force attacks yet easy to type on phones. Optionally generate a Wi-Fi QR code you can scan to join the network.
A Wi-Fi key is just a long password — the Password Generator gives you the same strength with more control, and a QR Code saves typing it into phones.
How to use the Wi-Fi Password
- 1 Set the password length — 16 to 20 characters is a good target for a home network.
- 2 Choose whether to avoid look-alike characters, which makes the password easier to type from a phone or a note.
- 3 Generate and copy the password, then share it by QR code if you have guests.
- 4 Update your router and note the password somewhere safe.
How to Use
Choose a length or a memorable passphrase style, then generate. Copy the password and, if you like, fill in the network name to get a scannable join QR code.
- Ambiguous characters excluded to avoid typing mistakes
- Length from 12 to 64 characters
- Passphrase mode for memorable Wi-Fi keys
- Guarantees at least one of each character type
- Optional Wi-Fi join QR code
Making a strong Wi-Fi key
WPA2/WPA3 requires at least 8 characters, but longer is safer against offline cracking — 16 or more random characters is ideal. Avoid dictionary words, personal dates and anything printed on the router label.
Frequently asked questions
What makes a password safe for Wi-Fi?
Length and unpredictability. WPA2 uses the password directly to derive the key, so a long random string is the practical defence — brute-forcing a 16-character mixed password is not feasible with current hardware. Avoiding words and patterns matters far more than adding symbols to a short one.
Why is there a length limit?
WPA2 accepts 8 to 63 printable ASCII characters. Below 8 the router refuses it; above 63 you would be entering a raw 64-hex-digit pre-shared key instead, which is a different mode. Staying in the middle of that range is both valid and strong.
How does QR sharing work?
The QR code encodes the standard Wi-Fi join string — network name, security type and password — so a phone camera can join the network without anyone typing it. Only share it with people you would give the password to anyway, since the code contains it in plain text.
