However, Wi-Fi connections are less secure than hard-wired options since it is easier for cybercriminals to intercept wireless signals and breach Wi-Fi networks. Given the vulnerability of these wireless networks, all Wi-Fi connections require users to enter a password to join the network.
You can leave your Wi-Fi network open, but doing so will leave you susceptible to hacking and other digital attacks. Setting up a strong password secures your Wi-Fi by locking out freeloaders and making it harder for hackers to compromise your network.
Every device you connect to your Wi-Fi network stores the login credentials, so you don’t have to enter your Wi-Fi password again. But for some reason, your device might “forget” the login credentials and keep asking for a password whenever you try to connect to Wi-Fi.
This guide explains what you can do to troubleshoot and fix a Wi-Fi network that keeps asking for a password on your devices.
Why Is My Device Always Asking for a Wi-Fi Password?
Knowing the causes of this problem can help you fix the issue quickly and restore your Wi-Fi connection.
Here are a few reasons Wi-Fi keeps asking for passwords on previously connected devices.
1. Captive Portal
This captive portal adds a security layer to the Wi-Fi network by requesting new users to enter a username and password.
Guest Wi-Fi Captive Portals
It also monitors incoming and outgoing traffic, blocking internet access for suspicious devices.
When you log in via a captive portal page, the network creates a timed session for your device.
Once the session times out, your device will disconnect from the network, and the router will erase all saved info about your device.
Since the router has no information about your device, the Wi-Fi network will ask for a password and you must log in afresh to begin a new session.
2. Modified Login Credentials
A Wi-Fi network might keep asking for a password if there are changes to the login credentials.
The network admin may opt to change and strengthen the password to secure the network after a hacking attempt or digital attack.
If you don’t have the new, modified login credentials, you won’t connect to the network, and your Wi-Fi will keep asking for a password on your previously connected device.
The only solution is to request the admin for the new password to reconnect to the Wi-Fi network.
3. Windows Update
Wi-Fi authentication errors are common after an operating system software update.
Installing a Windows operating system update may modify your saved login settings, requiring you to re-enter your Wi-Fi password.
Before installing a Windows update, create a system restore point and back up your data to avoid any issues.
You can reverse the changes if the update is already installed using the system restore function.

4. Misconfigured Network Settings
Misconfigured or corrupt network settings can cause your Wi-Fi to keep asking for passwords on your devices.
Performing a reset on your router and connected devices can help resolve authentication and connectivity issues.
However, you must set your password afresh and enter it on your devices to establish a connection.
5. Outdated Firmware
Your smartphone, tablet, or smart TV might constantly ask for a password if it requires a firmware update.
Most manufacturers regularly push through security and firmware updates to fix stubborn software bugs affecting their devices.
Failure to install these updates might result in software hitches messing up your device settings, leading to Wi-Fi authentication issues.
The quickest way to solve this problem is to update your device’s firmware to the latest version.
