WiFi passwords (WPA2/WPA3) must be 8-63 characters. Most home routers ship with weak default passwords that are scraped by Wi-Fi scanners. Generate a strong replacement that resists offline cracking, then update your router admin panel. Bonus: pair with our QR Code Generator's WiFi mode to share the password to guests instantly.
When to use this
Use when: setting up a new router, replacing the printed-on-the-box default password, separating guest WiFi from main network, refreshing your office WiFi after staff turnover.
Frequently Asked Questions
What length should a WiFi password be?
16+ characters for home WiFi, 20+ for office. WPA2/WPA3 supports up to 63 chars. Long passwords resist offline cracking attempts that record handshakes and brute-force later.
Should I use a passphrase or random password for WiFi?
Both work. Random is stronger per character; passphrases are easier to dictate. For guests, share via WiFi QR code instead of typing - our QR generator has a dedicated WiFi mode.
