Wi-Fi password generator.

A strong random Wi-Fi password for your router, easy to read out and type on a phone or smart TV. Made on your device, nothing sent or saved.

How it works

Random characters: every character comes from crypto.getRandomValues with rejection sampling. Letters and numbers are always included; look-alike characters (0 O 1 l I) are off by default because you will often read this one out or type it on a TV remote.
Dashes are part of the password: the optional blocks of 4 (like Kd7P-q3Xm-…) make it easier to read, and you must enter the dashes. The entropy figure counts only the random characters, because the dashes are in fixed places.
Length limit: a WPA/WPA2-Personal passphrase is 8 to 63 ASCII characters. The slider stops at 50 random characters so that, with dashes, the total never exceeds 63. WPA3-Personal (SAE) passwords are not bound by that limit, but a network that also allows WPA2 still needs a passphrase within it.
Private: no network request and nothing stored. This tool does not talk to your router; you paste the password into its settings yourself.

A 20-character letters-and-numbers password without look-alikes carries about 117 bits of entropy. For a longer, memorable alternative use the Diceware passphrase generator, and for other accounts the password generator.

FAQ

How long can a Wi-Fi password be?

A WPA/WPA2-Personal passphrase is 8 to 63 ASCII characters. This generator makes up to 50 random characters, and with dashes the total stays within 63.

What makes a good Wi-Fi password?

Length and randomness. A random 20-character password of letters and numbers carries about 117 bits of entropy and is still easy to type. Avoid names, addresses and the router’s default password.

Do I have to type the dashes?

Yes, if you choose grouping, the dashes are part of the password. Untick the option for a plain string, and the entropy figure will stay the same because only the random characters count.

Should Wi-Fi passwords include symbols?

They are optional. Symbols widen the character set, but letters and numbers are easier to read out and enter on a TV or console, and a longer password gains more than a larger set does. Some devices handle special characters poorly.

Does this change my router’s password?

No. This page only makes a password. You copy it and set it yourself in your router’s admin settings, then reconnect your devices.

Is the Wi-Fi password sent or stored anywhere?

No. It is generated in your browser with no network request and no storage.
