Wi-Fi Password Generator

Updated October 10, 2026

How this generator works

The password is made on your device by the browser’s cryptographic random generator — the same one browsers use for encryption keys. Nothing is sent to our server or stored: close the page and the password exists only where you pasted it. Each character is picked with equal probability from the chosen set, so the strength shown under the field is an exact count of the randomness, not an estimate based on how the password looks.

• Random uses upper- and lowercase letters, digits and, if you leave them on, ten symbols that routers and devices accept without trouble: ! # % + - = ? @ _ ~. Quotes, spaces, backslashes and semicolons are left out on purpose.
• Easy to type gives groups of four lowercase letters and digits, like k7mp-x3vt-9hdr-q2wn. Typing that with a TV remote or a game controller takes a fraction of the effort, and four groups still carry 80 bits of randomness.
• Avoid look-alike characters drops 0, O, o, 1, l and I, so nobody confuses them when reading the password from a sticker or a screen.

What makes a Wi-Fi password strong

Length and randomness, not clever substitutions. With WPA2, anyone within range can record the moment a device connects and then try guesses on their own computer, as fast as their hardware allows, without touching your router again. A password built from a name, a date or a dictionary word falls quickly to such guessing; 20 random characters do not. WPA3 closes this offline guessing, but many networks still run WPA2 or a WPA2/WPA3 mix for older devices, so a strong password still matters.

As a rule of thumb, aim for at least 60 bits — a 12-character random password or three easy-to-type groups — and prefer 80 bits or more. The default here, 20 random characters, gives about 120 bits.

Rules a Wi-Fi password has to follow

• 8 to 63 characters. That is the limit of WPA2 and WPA3 Personal; the generator stays within it.
• Plain characters only. Letters, digits and common symbols from a US keyboard. Letters with accents, emoji or Cyrillic may be accepted by the router but not by every device.
• Case matters. Home2026 and home2026 are different passwords.
• If your router rejects a symbol, switch symbols off and generate again — a few older routers and printers allow only letters and digits.

Setting and sharing the new password

1. Copy the password and open your router’s settings page. Our guide on how to change your Wi-Fi password shows where the field is on TP-Link, NETGEAR, ASUS, Linksys and other routers.
2. Paste it into the Wi-Fi password field (often called WPA Key, Passphrase or Pre-Shared Key) and save. All devices disconnect and have to join again with the new password.
3. Share it without typing: the Wi-Fi QR code generator turns the network name and password into a code that phones join by scanning. The link under the generator opens it with this password already filled in.

The Wi-Fi password and the router’s admin password are two different things. If the admin login is still the factory default, change the router admin password too — anyone on your Wi-Fi can try the default one.

Wi-Fi password generator: frequently asked questions

Is it safe to generate a Wi-Fi password online?

With this generator, yes: the password is created by your browser on your device and is never sent over the internet. You can even disconnect from the internet after the page loads and it keeps working.

How long should a Wi-Fi password be?

At least 12 random characters; 16–20 is better, and the limit is 63. Length adds far more strength than symbols: every extra random character multiplies the number of possible passwords.

Can I use spaces or special characters in a Wi-Fi password?

The standard allows spaces and all printable ASCII symbols, but some devices handle quotes, spaces and backslashes badly. This generator uses only symbols that work everywhere.

What is an easy-to-type Wi-Fi password?

A password of short groups of lowercase letters and digits, such as k7mp-x3vt-9hdr-q2wn. It is quick to enter with a TV remote and still strong because every character is random.

Do I need to change my Wi-Fi password regularly?

Not if it is strong and only people you trust know it. Change it when someone who should not have access knows it, when you find an unknown device on your network, or if you have shared it widely.
