How to create strong password for Wi-Fi

A very strong password can be long, symbols, words that you don't use. Do not use date of birth, name, pets etc. Apple can make a strong password for you in your passwords settings when you try to add a new password to save in the key-chain or password in iPhone settings.

To change your password you need to log in into your modem website by using the back of your modem details which includes password, ip,mac address and more.

When you use your modem instruction to log in there you can change your password and make it more stronger. Since most providers have a default password.

Just in case, you need to change 2.5 and 5 ghz password to save it.

The Wi-Fi password is set up on the router, not on your iPhone. You need to log in to the router’s control center using a web browser to change the Wi-Fi password. Usually the default Wi-Fi password that came with the router is strong enough. It should be on a label on the router.
