Fair random selection
Rejection sampling removes modulo bias before values are mapped to characters or words.
Your Wi-Fi password should protect your network, not reveal your identity.
Phone numbers, street names, pet names, and default router serial numbers are easy clues for neighbors or wardrivers. A random 20–24 character Wi-Fi key eliminates predictable patterns.
Practical advice: Use 20–24 random characters for WPA2/WPA3 Personal networks, and share access with visitors via QR code or guest networking.
Choose WPA3 or WPA2-AES security
Select WPA3-Personal (SAE) when modern devices support it, or WPA2/WPA3 transition mode for older appliances. Never use obsolete WEP or WPA-TKIP protocols.
Change the router administrator password too
The Wi-Fi network key (SSID password) and router administration login protect different layers. Always set separate, unique passwords for both.
Use a dedicated Guest Network
A separate guest Wi-Fi network isolates smart home IoT devices and visitor phones from your primary computers, NAS drives, and network printers.
FAQ
Before you use the result.
How long should a Wi-Fi password be?
A random 20 to 24-character password is the sweet spot between insurmountable brute-force resistance (~120+ bits) and practical device entry. WPA2 supports up to 63 characters.
Should a Wi-Fi password contain special symbols?
A few safe punctuation marks (!@#$%&*+-_=.?) are fine, but avoiding ambiguous symbols makes typing on TV remotes and gaming consoles much faster without losing security.
How do I share my Wi-Fi password easily?
You can generate a Wi-Fi QR code that guests can scan with their phone camera to connect instantly without typing a single character.
