Why Use a WiFi Password Generator?

Secure your network with passwords designed specifically for WiFi.

WPA2/WPA3 Optimized

Generated passwords meet all router requirements and work with modern security protocols.

Easy to Share

No confusing characters. Guests can easily type passwords when you read them aloud.

QR Code Support

Generate QR codes guests can scan to connect instantly without typing.

Strong Security

Even "easy" passwords provide sufficient entropy to resist attacks.

Memorable Options

Use passphrase mode for passwords you can actually remember.

Verified Strength

See crack time estimates displayed instantly so you know your network is secure.

WPA2 vs WPA3 Security

Understanding the security differences helps you protect your network.

WPA2-PSK

Most common (since 2004)
  • ⚠ Vulnerable to offline dictionary attacks via captured handshake
  • ⚠ KRACK vulnerability (patched, but older devices at risk)
  • ✓ Universal device compatibility
  • ✓ Strong with 16+ character random passwords

Recommendation: Use 16+ character random password. Weak passwords can be cracked in hours.

WPA3-SAE

Modern standard (since 2018)
  • ✓ Immune to offline dictionary attacks (SAE handshake)
  • ✓ Forward secrecy protects past sessions
  • ✓ Protected Management Frames (PMF) required
  • ⚠ Older devices may not support WPA3

Recommendation: Use WPA3 if all devices support it. Enable "WPA2/WPA3 Transitional" for compatibility.

Common WiFi Attacks & Protection

Know the threats to defend against them.

1

Handshake Capture + Offline Crack

Attacker captures WPA2 handshake, cracks password offline

WPA2 Vulnerable WPA3 Protected

Defense: Use 16+ character random passwords. Even with captured handshake, cracking takes centuries with strong passwords.

2

Evil Twin Attack

Fake access point with same name tricks users into connecting

WPA2 Vulnerable WPA3 Partial

Defense: Use unique network names. Enable "Protected Management Frames" (PMF). Verify you're on correct network before entering password.

3

Default Password Exploitation

Many users never change router default credentials

User Error

Defense: Change both WiFi password AND router admin password immediately. Use different passwords for each.

Frequently Asked Questions

Complete WiFi Security Guide

Your WiFi network is often the gateway to your entire digital life—computers, phones, smart home devices, and everything they contain. A weak WiFi password is an open invitation to attackers who can then intercept traffic, attack devices, and steal credentials.

Why WiFi Passwords Matter More Than You Think

Unlike online services with rate limiting and account lockouts, WiFi attacks happen offline. With WPA2, an attacker who captures your network handshake can test billions of passwords per second using tools like Hashcat. Common passwords crack in seconds; random 12-character passwords take centuries.

Router Security Beyond the Password

A strong WiFi password is necessary but not sufficient. Complete router security includes:

  • Change default admin password (different from WiFi password)
  • Disable WPS (WiFi Protected Setup)—it has known vulnerabilities
  • Enable WPA3 if supported, or WPA2-AES (never WPA/TKIP)
  • Keep router firmware updated
  • Disable remote management unless needed
  • Consider a guest network for visitors and IoT devices

Guest Networks: Best Practice

Most modern routers support guest networks that isolate visitors from your main network. Guests can access the internet but not your computers, printers, or NAS. Use a simpler "easy to share" password for guests, and a maximum-security password for your main network. Change the guest password periodically or whenever untrusted devices have connected.
