When you are trying to connect to a Wi-Fi network, the device will first send a connection request, with the password to the router. Then, the router will compare the password stored with the received data.
If the data matches, then you see that the device gets connected. If it doesn't, you will get an authentication error. So, the Wi-Fi authentication problem will not let your Android device connect to the Wi-Fi network.
The Wi-Fi authentication problem is occurring on an Android device because of multiple reasons. They are:

First, reset the connection between the router and the Android device. This solution has helped many users in solving this particular error.
Open Settings and select Wi-Fi in the Network Connections option.
Wi-Fi connection names will be listed. Find the one you are trying to connect to and then long-press on it. You can see two option( Forget Network and Modify)

Sometimes the electronic devices will be working correctly when restarted. So, try to restart the router and see if you are able to connect your device to the particular Wi-Fi network.
Turn off the wireless router and wait for a few minutes and then turn on the router again. It will take some time before any device connects to the router.
After turning on the router, connect your device with the WiFi network, and check if the connection is working without issue.
One of the best solutions to fix this issue is to reset the network settings of your device..
Open Settings and go to Backup & Reset option.
Now select Network Reset settings option.
Now click Reset Settings.
Once the process completes, open the Wi-Fi and try to connect to the Wi-Fi network.
Turning on Airplane mode can be useful to fix these issues because often mobile network signals may interfere with the wireless network. When you enable the Airplane mode, the RF(Radio Frequency) signal on your phone will be turned off.
Turn off the mobile and Wi-Fi network in your device before clicking the airplane mode. You can also do this by clicking the airplane symbol in the quick settings menu.
With the Airplane mode on, now turn on Wi-Fi. If your device gets connected with the Wi-Fi network successfully then you can open settings and turn off the Airplane mode.
Modems can support a limited number of devices. Go to the Wi-Fi router settings and see the maximum number of devices that can be connected to the WiFi network. Increase the number of devices and save the settings. Now your device may get connected to the WiFi network.
Sometimes the network security type can be a reason for this particular issue. If you know the credentials of the router, you can change the network security type within minutes.
If WPA is the security protocol, change it to WPA2 and vice versa. After that reconnect to the wireless network.
Often the authentication problem occurs when the credentials of the WiFi network do not match. You might have entered the right password, but there are chances that you are connecting to some other network with the same name.
Change the network name is the best solution and to avoid any confusion. Now enter the password and check if your device is able to connect to the wifi network.
