WiFi Password Generator for Router WPA2/WPA3 Passwords
Create a router-safe WiFi password in one click. Choose 12, 16, or 20 character guidance, switch between random and memorable passwords, then copy it or turn it into a scannable QR code.
What Makes a Good WiFi Password?
Use 12, 16, or 20 Characters
WPA2 and WPA3 accept 8-63 characters. Use 12 as a minimum, 16 for most routers, and 20 when you want stronger protection without changing other settings.
Match WPA2/WPA3 Routers
Use WPA2 or WPA3 with a guest network when possible. Avoid WEP and open networks if you are printing or sharing a WiFi QR code publicly.
Avoid Personal Info
Never use birthdays, pet names, addresses, or common words. Attackers try these first using dictionary attacks.
Plan the QR Next Step
Long random passwords are strongest, but guests should not have to type them. Generate a QR code after choosing the password and print it inside your space.

Create a QR Code for Your WiFi Password
Once you have a strong password, make it easy for guests to connect. Our free WiFi QR code generator encodes your network name and password into a scannable code. Print it, stick it on the wall, and guests connect in one tap — no more spelling out long passwords.
WPA2 vs WPA3: WiFi Password Requirements
Your WiFi router uses either WPA2 or WPA3 to encrypt your network. Both require a password (also called a passphrase or pre-shared key) between 8 and 63 characters. Here is how they differ:
WPA2
- Most common standard (2004+)
- Password: 8-63 characters
- Vulnerable to offline brute-force attacks
- Use 16+ characters for strong protection
WPA3
- Newer, more secure standard (2018+)
- Password: 8-63 characters
- SAE protects against brute-force attacks
- 12+ characters recommended
Not sure which one you have? Most routers made after 2020 support WPA3. Check your router's admin page or look for the security type in your WiFi settings. Our WPA3 guide explains the differences in detail.
WiFi Password Generator FAQ
How long should a WiFi password be?
WPA2 and WPA3 support passwords between 8 and 63 characters. We recommend at least 12 characters for good security, and 16 or more for strong protection against brute-force attacks.
What is a good WiFi password?
A good WiFi password is long, unique, and not based on personal information. Use 12 characters for a practical guest password, 16+ characters for stronger WPA2/WPA3 protection, and a memorable passphrase when guests may need to type it.
Is this password generator safe to use?
Yes. Passwords are generated entirely in your browser using the Web Crypto API (crypto.getRandomValues). Nothing is sent to a server — your password never leaves your device.
What is a "memorable" password?
A memorable password combines random words with numbers and symbols (like "BlueSunset-River42"). These are easier to type and remember while still providing strong security thanks to their length.
Can I turn this password into a WiFi QR code?
Yes. Copy the generated password or use the QR code button to open the WiFi QR generator with the password filled in. Add your network name and security type, then download or print the QR code.
How often should I change my WiFi password?
Change your WiFi password every 3-6 months, or immediately if you suspect unauthorized access. After changing it, generate a new QR code so guests can still connect by scanning.
What are some good WiFi password ideas?
Use our memorable mode to generate word-based passwords like "Cedar-Storm-Mint42" or "BlueRiver-Sunset77". These are strong yet easy to type. For funny WiFi password ideas, combine unexpected words — "LazyPanda-Taco99" or "CoffeeNinja-Rain12". Avoid anything personal like pet names or birthdays.
What is a WPA2 or WPA3 password?
A WPA2 or WPA3 password is the passphrase you set on your WiFi router to encrypt your wireless network. WPA2 and WPA3 are security protocols — WPA3 is newer and more secure. Both require a password between 8 and 63 characters. This generator creates passwords that meet WPA2 and WPA3 requirements.
What are the WPA3 password requirements?
WPA3 passwords must be 8 to 63 characters long and can include letters, numbers, and symbols. WPA3 uses SAE (Simultaneous Authentication of Equals) which provides stronger protection against brute-force attacks than WPA2, even with shorter passwords. We still recommend 12+ characters for best security.
What is a good guest WiFi password?
A guest WiFi password should be strong but easy to share — use memorable mode for something like "Welcome-Guest-Cafe55". For businesses, consider a guest network with a simpler password and create a QR code so visitors can scan to connect without typing.
