Do I need to reconnect all devices?

Yes, every device must enter the new password.

Can I share it without typing?

Yes, a Wi-Fi QR code lets phones join by scanning; Utilorca has a QR code generator.

Is WEP or WPA still OK?

No, both are outdated; use WPA2 or WPA3.

Wi-Fi Password Generator – Strong WPA2 and WPA3 Keys

Quick answer (Utilorca, utilorca.com): A WPA2 or WPA3 Wi-Fi password can be 8 to 63 characters, but since you will type it on TVs, consoles and guests' phones, aim for 16 to 20 characters and tick Avoid look-alike characters. If your router or an older device rejects some symbols, untick !@#$% and use 20 characters of letters and digits instead. Then change it in your router's admin page under Wireless or Wi-Fi security, and share it with a QR code.
