Q: Log on screen for Internet password

Howdy Dwyday,

Thank you for visiting Apple Support Communities.

If the password changed for your network, try forgetting the network and re-adding it.

If you need help with your Wi-Fi password - Apple Support

In iOS: Tap Settings > Wi-Fi >  > Forget this network. Then try to rejoin.

There's also Reset your Network Settings, which resets all network settings.

If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network - Apple Support

Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you’ve used before.

Thank you for visiting Apple Support Communities.
