Wi-Fi Password Generator

Strong random Wi-Fi passwords for WPA2/WPA3 — easy-to-type options without look-alike characters.

Random characters, 8–63 (the WPA2/WPA3 limit).

Hyphens make the password easier to read aloud; they count toward the 63-character limit.

Passwords are generated in your browser with the Web Crypto API and are never sent to a server. Use WPA2 or WPA3 security on your router.

About this tool

Choose a length (8–63 characters, the WPA2/WPA3 limit), a character set and whether to split the password into groups of four. The “easy to type” set leaves out characters that are easy to mix up, like 0 and O or 1, l and I — handy when guests type the password on a phone or TV. Each password shows its entropy in bits. Everything is generated in your browser.

Frequently asked questions

WPA2 and WPA3 accept 8 to 63 characters. Longer is better: with WPA2 an attacker who captures the handshake can guess offline. 16 characters from the easy-to-type set (56 characters) give about 93 bits of entropy; 12 give about 70 bits.

The digits 0 and 1 and the letters O, o, l and I, which look alike in many fonts. That leaves 24 uppercase letters, 24 lowercase letters and 8 digits — 56 characters, still 5.8 bits of entropy per character.

Symbols add strength per character (75 possible characters gives 6.2 bits each), but some TVs, printers and smart devices have awkward keyboards. A few extra letters and digits give the same strength: 16 symbols-set characters ≈ 100 bits, 18 easy characters ≈ 105 bits.

Yes. WPA3-Personal uses SAE (Simultaneous Authentication of Equals), which resists the offline guessing attacks that work against WPA2-PSK. Use WPA3 if all your devices support it, or WPA2/WPA3 mixed mode, and a long random password either way.
