Generate strong, easy-to-share WiFi passwords for your home or office network. Optimized for WPA2/WPA3.
Use ⌘ + D to bookmark this toolYour WiFi password is the front door to your home network. Anyone who cracks it can intercept your traffic, access shared files and devices, use your internet for illegal activities, and even launch attacks against other devices on your network.
Default router passwords are particularly dangerous — attackers maintain databases of default credentials for every router model. If you haven't changed yours, your network is essentially wide open.
| Standard | Min Length | Max Length | Characters | Security |
|---|---|---|---|---|
| WPA3 | 8 | 63 | ASCII printable | Excellent |
| WPA2 | 8 | 63 | ASCII printable | Good (16+ chars) |
| WPA | 8 | 63 | ASCII printable | Weak (deprecated) |
| WEP 64 | 5 | 5 | Hex only | Broken |
| WEP 128 | 13 | 13 | Hex only | Broken |
WPA and WEP are considered insecure regardless of password strength. Upgrade to WPA2 or WPA3 if your router supports it.
The latest standard. Uses SAE (Simultaneous Authentication of Equals) which protects against offline dictionary attacks. Even if captured, handshakes can't be cracked offline.
Still widely used and secure with a strong password. Vulnerable to offline brute-force attacks on captured handshakes — which is why password length and randomness matter so much.
WPA (original) and WEP are severely broken. WEP can be cracked in minutes regardless of password strength. If your router still uses these, upgrade immediately.
WPA2/WPA3 passwords must be 8-63 ASCII printable characters. We recommend at least 16 characters. The maximum of 63 characters makes your network virtually uncrackable.

Generate speakable passwords from fake syllables. Easy to say aloud, type from memory, and share verbally.
Generate fun, memorable passwords children can actually remember. Word stories: red-panda-jumps-42.
At least 16 characters for WPA2 networks. WPA3's SAE protocol provides better protection, but a longer password never hurts. For maximum security, use 20+ characters.
For WiFi passwords you'll share with guests, "easy to read" mode avoids confusing characters (0/O, l/1). For maximum security, enable all characters — you only need to enter it once per device.
Use a WiFi QR Code Generator to create a scannable QR code. Guests can connect instantly by scanning it with their phone camera.
Change it if you suspect unauthorized access, after sharing it with temporary guests, or every 6-12 months as a precaution. Always change default router passwords immediately.
With WPA2, attackers can capture the 4-way handshake and attempt offline brute-force attacks. A 16-character random password makes this practically impossible — it would take thousands of years even with specialized hardware. WPA3 eliminates this attack entirely.
No. The WiFi password (PSK) controls who can connect to your network. The router admin password controls access to your router's settings page. Both should be strong and different from each other.
