Why Wi-Fi passwords need length
A home network password faces a different attack from a website password. Anyone within range can capture the handshake when a device joins a WPA2 network, take it away, and guess offline as fast as their hardware allows. Login limits do not apply. That makes length the only defence, and it is why this page defaults to 20 characters.
WPA2 and WPA3 personal networks accept passphrases from 8 to 63 characters. WPA3 replaces the handshake that allows offline guessing with one that does not, but most homes still run WPA2 or a mixed mode for older devices, so choose the password as if offline guessing were possible.
Why no look-alikes and no symbols
Wi-Fi passwords get typed on TV remotes and games consoles and read out loud. Leaving out symbols and the characters people confuse (I, l, 1, O, 0, o) makes that painless, and the extra length more than makes up the difference: 20 characters from the remaining 55 still carry about 116 bits.
Prefer something guests can say? A four or five word passphrase works well on a guest network.
Questions
How long should a Wi-Fi password be?
At least 16 characters, ideally 20 or more. Because a captured WPA2 handshake can be attacked offline, short Wi-Fi passwords are among the most commonly cracked.
Should I change the default router password?
Yes, both the Wi-Fi password and the router admin password. Default passwords are sometimes derived from the device serial number or MAC address and are listed online for some models.
Can I use spaces in a Wi-Fi password?
The WPA standard allows printable ASCII characters including spaces, but some devices handle them badly. Hyphens are safer.
