WiFi Password Generator
A WiFi password generator creates strong, router-compatible passwords for WPA2 and WPA3 wireless networks. WiFi passwords can be up to 63 characters and should use a full character set for maximum network security.
WiFi password requirements
WPA2 and WPA3 passwords (called the Pre-Shared Key or PSK) can be 8–63 printable ASCII characters. The recommended minimum for a home network is 12 characters with a mix of character types. Avoid passwords that are easy to shout across the room or find in a dictionary — your WiFi password protects every device on your network.
Special considerations for WiFi passwords
Some older router firmware and client devices may have trouble with certain special characters. If you encounter connection issues, try the "Exclude ambiguous" option or switch to an alphanumeric password. WPA3 networks (the latest standard) support the full ASCII character set reliably. The maximum allowed length of 63 characters means there's no reason to use a short WiFi password.
Frequently Asked Questions
WPA2/WPA3 allows 8–63 characters. For a home network, 12+ characters with mixed types is sufficient. For a business network, use 16–20 characters. Never use the default router password — change it to a randomly generated one.
WPA2 and WPA3 support all printable ASCII characters. However, some older client devices or router firmware may have issues with certain symbols. If you experience connection problems, try an alphanumeric password instead.
Modern iOS and Android devices support WiFi password sharing via QR code, eliminating the need to type it. You can also share through a password manager. Avoid writing it on a sticky note or leaving it visible in your home.
Change your WiFi password if you suspect it's been shared too widely, after a guest has visited, or if you've had devices on your network you no longer trust. Otherwise, a strong unique password doesn't need regular rotation.
