Pre-set for you: 20 characters from upper- and lowercase letters and numbers, with symbols off and look-alike characters (I, l, 1, O, 0, o) removed. That is about 116 bits of entropy. Change anything you like, or use the full Password Generator.
Why a Wi-Fi password needs different settings
An account password lives in a password manager and is pasted, so symbols cost you nothing. A Wi-Fi password is different: people type it on TV remotes, printer screens and friends’ phones, often while reading it off a card. Symbols are hidden behind extra keyboard screens, and characters like l, 1 and I get confused. Length gives the same security without that pain, so this page uses 20 easy characters instead of 12 hard ones.
How strong is it?
| Password style | Example pattern | Approximate strength |
|---|---|---|
| Router default (often 8 digits) | 48203917 | about 27 bits: weak |
| 12 letters and numbers | aB3dE5fG7hJ9 | about 70 bits: strong |
| 20 letters and numbers, no look-alikes (this page) | tR4mPq8Wz2KxN7bHs5Yc | about 116 bits: very strong |
WPA2 and WPA3 passwords can be 8 to 63 characters long, so 20 fits every router. Never use one of the example patterns above; generate your own.
How to change your Wi-Fi password
- Generate a password above and press Copy.
- Open your router’s app or admin page (the address is usually on the router label) and go to the Wi-Fi or wireless security settings.
- Choose WPA2 or WPA3 security, paste the new password and save. Your devices will disconnect.
- Reconnect each device with the new password, or make it easy with a Wi-Fi QR code that guests can scan.
Frequently asked questions
Is the password generated securely?
Yes. It uses your browser’s cryptographic random number generator (crypto.getRandomValues), and the password is never stored or sent over the internet.
Should I add symbols for extra security?
You can, but adding four more letters gives a bigger boost than switching on symbols, and keeps the password easy to type.
How often should I change my Wi-Fi password?
Change it when someone who should no longer have access knows it, such as a former tenant or employee, or if you suspect unknown devices on your network.
