Wi-Fi Password Generator
Generate random, strong passwords suitable for Wi-Fi networks. Choose whether to avoid ambiguous characters like 0/O and 1/l/I that can be confusing when shared verbally or in print. Generate one password or many at once.

Private by design. Your Wi-Fi password is generated locally and never saved, uploaded, or shared — only your settings can be, and only when you choose.

What it does
The Wi-Fi Password Generator creates random, cryptographically secure passwords designed for wireless networks. Choose the desired length and decide whether to exclude ambiguous characters that can be confusing when written or spoken aloud.
Common use cases
- Setting up new Wi-Fi networks with strong, random passwords.
- Changing default router passwords for security.
- Creating and rotating guest network credentials.
- Periodic password rotation for network maintenance.
Settings
- Length — the number of characters in the password (8–63 characters, fitting standard Wi-Fi requirements).
- How many — generate one password or batch multiple passwords at once.
- Avoid ambiguous characters — when enabled, removes characters like 0, O, 1, l, and I that look similar and can be misread when written or spoken.
Privacy note
Everything runs locally in your browser using the Web Crypto API. Generated passwords are never uploaded, logged, or sent to a server. They are never saved automatically and never included in share links — only your generation settings can be saved or shared.
Security notes
This generator uses the browser’s cryptographic RNG and is never seeded. Each generation produces completely random output that cannot be reproduced — secure generators do not accept seed values.
FAQ
Why is the maximum 63 characters? That’s the WPA2/WPA3 passphrase limit — Wi-Fi standards allow 8 to 63 printable characters, and this tool stays inside it so every generated password is guaranteed to be accepted by your router.
How long should a Wi-Fi password actually be? 16+ random characters puts offline cracking far out of reach; 20–24 is a comfortable sweet spot between security and the pain of typing it into a smart TV with a remote control. The real risk is usually a guessable password, not a short random one.
Why exclude ambiguous characters? Wi-Fi passwords get read aloud and typed on TVs, e-readers, and other awful keyboards. Dropping 0/O and 1/l/I costs a sliver of entropy (add a character or two to compensate) and saves the third mistyped attempt.
Password or passphrase for Wi-Fi? Both work. Random characters (this tool) are strongest per character; word-based passphrases (the Passphrase Generator) are easier to read to a guest across the room. At 20+ characters either is far beyond practical cracking.
