WPA2/WPA3-Personal accepts an 8–63 character password. We default to settings that are strong, but also easy to type on a TV remote or read off a printed card — tweak freely.
< > " ' \ occasionally trip up older router firmware or IoT devices, which is why they're off by default here (turn them on freely if your hardware supports it). A long random password or a multi-word passphrase both work — a passphrase is often the more practical choice since guests only have to type it once, correctly, on a remote.
Sized for WPA2/WPA3
Defaults to 20 characters, well within the 8–63 character range every WPA2/WPA3-Personal router accepts, with ambiguous characters (0/O, l/I) excluded so it's easy to read off a printed card.
Scannable QR Code
Add your network name and get a QR code guests can scan to join instantly — no typos, no reading a password aloud across the room. Generated entirely in your browser.
100% Private
Generation and the QR code happen entirely in your browser — your password and network name are never transmitted, stored, or logged. The optional breach check sends only a partial hash, never the password itself.
Why your WiFi password isn't just "a password"
A WiFi pre-shared key (PSK) plays by different rules than a website password. It's used during the WPA2/WPA3 4-way handshake, which is designed so the key itself never crosses the air in the clear — but that handshake can be captured and attacked offline at leisure, so the key still needs to be long and random rather than memorable. This generator defaults to a length that stays comfortably out of reach of any practical offline attack.
If your router supports WPA3, use it — its SAE key exchange (see Sources below) closes the offline dictionary-attack weakness that WPA2's handshake has always had, by requiring an attacker to interact with the access point for every single guess instead of cracking a captured handshake in isolation. Either way, put guests and smart-home devices on a separate guest network rather than sharing your main WiFi password with them — it's the single biggest practical upgrade most home networks are still missing.
