How can I tell if a network requires a password?
A password-protected Wi-Fi network has a lock icon 
next to its name.
In iOS:
On Mac:
What if I don’t know my Wi-Fi password?
If your cable or Internet provider set up your Wi-Fi router:
- Look for a label on the side or bottom of the router—it might list the default password.
Network Name (SSID): XXXXX
Network Key (Password): XXXXXXXXXX
- If your provider gave you a setup sheet, look it over for your network information and password.
- Contact your cable or Internet provider for help recovering or resetting your Wi-Fi password.
If you own your Wi-Fi router:
- If someone else set up your network, ask that person for help.
- If you never created a personal password, check the brand of your Wi-Fi router and go to their website to find the default password.
- To reset the password, either call the router manufacturer or check their website or user guide.
If you’re using a public Wi-Fi network at a library, hotel, business, or other shared space:
- Look for signs or information sheets that list the Wi-Fi network name and password.
- Some public Wi-Fi networks might ask you to log in after joining the network.
- Ask a staff member for help.
What if I know my password, but the network won’t accept it?
In iOS: Tap Settings > Wi-Fi > 
> Forget this network. Then try to rejoin.
On your Mac: Go to System Preferences and click Network > Advanced. Highlight your Wi-Fi network by clicking on it. Click the minus icon and then choose Remove. Try to rejoin your Wi-Fi network.
If the network still won’t accept your password, make sure:
- You’re trying to join your network and not a nearby, similarly named network.
- You’re entering the password correctly. Wi-Fi passwords are case-sensitive.
- If someone else set up your network, follow steps to confirm that you’re using the correct password.
