Mac Asks for a WPA2 Password? What to Check

A WPA2 password prompt asks for the Wi-Fi network’s credentials. First check whether your Mac can join the network or joins without internet.

Check the network and its password

Select the intended network from the Wi-Fi menu, then enter that network’s password. This is the connection sequence in Apple’s Mac internet setup guide.

Confirm the password with whoever manages the router before changing settings. Check the network name, capitalization and any characters that are easy to confuse. The prompt alone is not enough to diagnose a macOS bug.

Forget a saved network and rejoin

If the network is already saved, you can remove its stored settings and enter the confirmed password again.

Open System Settings, select Wi-Fi, then Advanced. Beside the saved network, open the More Options menu, choose Remove From List and confirm Forget. Rejoin from the Wi-Fi menu.

Apple’s forget-network instructions include an important consequence: devices using iCloud Keychain with the same Apple Account also forget that network. Have the password ready before proceeding. A managed device may restrict this option.

If Wi-Fi connects but the internet does not

This is a separate stage. Apple’s connected-but-offline troubleshooting starts after the Mac has joined Wi-Fi.

Restarting the Mac renews its assigned network address. Apple also provides a manual DHCP renewal option. That addresses an IP-address lease problem; it does not replace the password needed to join a secured network.

If you manage the router, check its connection and consider restarting it. For a work, hotel or shared network, ask the administrator to investigate.

Use diagnostics before broader changes

Hold Option while opening the Wi-Fi menu, then choose Open Wireless Diagnostics. Apple also recommends checking for available macOS updates and testing another network when internet access still fails.

Record the exact message and whether another network works before contacting support. That is more useful than applying several unrelated changes at once.
