WiFi Password Generator
Generate strong WiFi passwords that are secure yet easy to share.
Generate a Random WiFi Password for Any Router
Your WiFi password protects your entire home or office network. A weak WiFi password can be cracked in minutes using widely available tools, giving attackers access to all devices on your network. Our WiFi password generator creates strong, random WPA2 and WPA3-compatible passwords without confusing symbols — making them easy to read and type on phones, smart TVs, and IoT devices. Works with any router brand: Netgear, TP-Link, Linksys, ASUS, and more. Generated entirely in your browser with cryptographic randomness. For maximum security, change your WiFi password periodically and use WPA3 if your router supports it.
Key facts
- WiFi passwords must be 8–63 printable ASCII characters for WPA2 and WPA3 compatibility.
- A 16-character alphanumeric password provides ~95 bits of entropy — infeasible to brute-force.
- WPA3 (SAE) eliminates offline dictionary attacks, but a strong password is still required per the Wi-Fi Alliance specification.
- Avoid symbols in WiFi passwords — they are hard to type on smart TVs, game consoles, and IoT devices.
Why WiFi passwords need special treatment
WiFi passwords are different from website passwords in two important ways. First, you need to type them manually on every device — phones, laptops, smart TVs, game consoles, printers, IoT devices. Symbols like #, @, and $ are hard to find on TV remotes and some device keyboards, which is why this generator uses only letters and numbers. Second, WiFi passwords can be attacked offline: an attacker captures the WPA handshake and brute-forces it on their own hardware without rate limiting. This makes length and randomness especially critical — NIST Special Publication 800-63B recommends at least 8 characters, but for WiFi we recommend 16 or more.
WPA2 vs WPA3: what your password protects
With WPA2 (still the most common protocol), your password is hashed using PBKDF2 with 4,096 iterations of SHA-1. A determined attacker with a GPU cluster can test millions of guesses per second against the captured handshake. An 8-character alphanumeric password can be cracked in days. A 16-character one pushes the time well beyond feasibility. WPA3 uses SAE (Simultaneous Authentication of Equals), which makes offline brute-force attacks significantly harder — as defined in the Wi-Fi Alliance WPA3 specification. If your router supports WPA3, enable it — but use a strong password regardless.
| WPA2-Personal | WPA3-Personal | |
|---|---|---|
| Standard | IEEE 802.11i (2004) | Wi-Fi Alliance (2018) |
| Key exchange | PSK (Pre-Shared Key) | SAE (Simultaneous Authentication of Equals) |
| Offline brute-force | Vulnerable — attacker can crack captured handshake offline | Resistant — each attempt requires live interaction with the router |
| Password length | 8–63 ASCII characters | 8–63 ASCII characters (1–128 in SAE spec) |
| Recommended minimum | 16+ characters | 12+ characters (protocol is stronger) |
| Forward secrecy | No — compromised password exposes past traffic | Yes — each session uses a unique key |
| Protected Management Frames | Optional | Required |
How to change your WiFi password on any router
Log into your router's admin panel — the address depends on the brand. Netgear: routerlogin.net or 192.168.1.1. TP-Link: tplinkwifi.net or 192.168.0.1. Linksys: 192.168.1.1. ASUS: router.asus.com. Navigate to the Wireless or WiFi settings section. Look for the password, passkey, or pre-shared key field under your network name (SSID). Select WPA2-Personal or WPA3-Personal as the security mode. Paste or type your new password, save the settings, and reconnect all your devices.
How to share your WiFi password securely
Never send a WiFi password over SMS, email, or chat — those copies persist in message history forever — and skip the sticky note on the fridge. For remote sharing, use an encrypted one-time link that self-destructs after being read: generate the password above, then click "Share as link". For in-person sharing, a QR code is the fastest option — guests scan it instead of typing 16 random characters on a phone keyboard.
Share WiFi from an iPhone or Mac
Apple devices share WiFi automatically between people in each other's contacts: when a guest with an iPhone, iPad, or Mac tries to join your network, your device pops up a "Share Your Wi-Fi Password" prompt — one tap and they are connected, without ever seeing the password. It requires both devices to have WiFi and Bluetooth on and the other person's Apple ID email in your contacts. For guests on Android or Windows, that prompt never appears — copy the password and send it as a one-time link instead.
Share WiFi from an Android phone
On Android 10 and newer, open Settings → Network & internet → Internet, tap the gear next to your network, then tap Share — the phone shows a QR code (and the password in plain text below it). A guest scans the code with their camera and joins instantly. One caution: that QR encodes your password in plain text, so show it in person rather than screenshotting it into a chat. For remote guests, a self-destructing one-time link is the safer route.
Share WiFi from Windows
On current Windows 11, Settings can share WiFi directly: go to Settings → Network & internet → Wi-Fi → your network's properties and choose "View Wi-Fi security key" — Windows reveals the password and displays a QR code a guest can scan to join. On Windows 10 or older builds without the QR option, retrieve the saved key with netsh wlan show profile name="YourNetwork" key=clear in a terminal (read the "Key Content" line). For remote sharing from any Windows version, send the key as a one-time link rather than pasting it into email or chat.
Guests and rentals: use a guest network
If you host visitors regularly — or run an Airbnb — put them on a separate guest network. It isolates their devices from your computers, printers, and smart home; it can carry a simpler password than your main network; and you can rotate that password between stays without reconnecting your own devices. Send each guest the current password as a one-time link in the check-in message — the link destroys itself after being opened, and rotating the password after checkout cuts off any copies that linger.
Frequently asked questions
- Why no symbols in WiFi passwords?
- Most WiFi passwords are typed on devices with limited keyboards — smart TVs, game consoles, IoT devices. Symbols like @#$% are hard to locate on these keyboards and slow down the process. A 16-character alphanumeric password still provides about 95 bits of entropy, which is more than sufficient for WiFi security.
- How long should a WiFi password be?
- At least 12 characters, ideally 16 or more. WiFi passwords can be attacked offline (the attacker doesn't need to stay connected to your network), so they need more length than typical website passwords. Our default of 16 characters provides a strong security margin.
- What is a WiFi passkey and how do I create one?
- A WiFi passkey (also called a pre-shared key or PSK) is the password used to authenticate devices on your wireless network. For WPA2-Personal and WPA3-Personal, the passkey can be 8 to 63 characters. To create a strong one, use this generator to get a random 16-character password, then enter it in your router's wireless security settings under the passkey or pre-shared key field.
- Does this work with WPA2 and WPA3 routers?
- Yes. WPA2 and WPA3 both accept passwords between 8 and 63 ASCII characters. This generator creates 16-character alphanumeric passwords by default, which are compatible with all WPA2 and WPA3 routers from any brand — Netgear, TP-Link, Linksys, ASUS, and others.
- How often should I change my WiFi password?
- Change it when a device is lost or stolen, when someone who knows the password no longer needs access, or if you suspect unauthorized access. For home networks with WPA3, routine changes aren't strictly necessary. For WPA2 networks in shared environments (offices, rentals), consider changing it every 3-6 months.
- Can someone hack my WiFi with a strong password?
- With a 16-character random password and WPA2/WPA3, brute-forcing the password is computationally infeasible. Attackers would need to exploit router firmware vulnerabilities or use social engineering instead. Keep your router firmware updated and disable WPS (WiFi Protected Setup) for best security.
- What is the strongest type of WiFi password?
- The strongest WiFi password is a randomly generated string of at least 16 alphanumeric characters used with WPA3-Personal encryption. WPA3 uses SAE (Simultaneous Authentication of Equals) which prevents offline brute-force attacks entirely. If your router only supports WPA2, use 20+ characters to compensate for the weaker key exchange protocol.
- Is a 12-character WiFi password secure enough?
- A 12-character random alphanumeric password provides about 71 bits of entropy — enough for most home networks with WPA2 or WPA3. However, if your network is a high-value target or you use WPA2 (which is vulnerable to offline attacks), we recommend 16 characters or more for a stronger security margin.
- Can my neighbor hack my WiFi password?
- If you use a weak or common password (like "password123" or your address), yes — tools like Hashcat and Aircrack-ng can crack short WiFi passwords in hours. With a random 16-character password, brute-forcing would take longer than the age of the universe. The risk shifts to router vulnerabilities and WPS exploits, so disable WPS and keep your firmware updated.
- What is the difference between a WiFi password and a WiFi key?
- They are the same thing. "WiFi password," "WiFi key," "network key," "wireless key," and "pre-shared key (PSK)" all refer to the passphrase you enter to connect a device to your wireless network. The technical term used in the WPA2/WPA3 standards is "pre-shared key" but most router interfaces label it as "password" or "passphrase."
- What characters are allowed in a WiFi password?
- WPA2 and WPA3 accept any printable ASCII character (codes 32–126) including letters, numbers, symbols, and spaces. The password must be between 8 and 63 characters. However, we recommend avoiding symbols because they are difficult to type on smart TVs, game consoles, and IoT device keyboards. A 16-character alphanumeric password is both compatible and highly secure.
