Connecting your Android phone to a new Wi-Fi network is usually something you do without thinking.You find the network, enter the password, and get on with whatever you need an internet connection for.But that quick process can expose you to problems you might not notice until it's too late, especially when you're using networks you don't fully control.
The good news is that you don't need to be a security expert to make your phone safer on a new connection.Android includes several settings that can give you more control over how your device communicates with the network, what information it exposes, and how it uses the connection in the background.Some may already be enabled on your phone, while others are worth checking whenever you connect somewhere unfamiliar.
Taking a few moments to adjust them can make using Wi-Fi a little safer and more predictable.Set your phone to a secure DNS provider Extra security and privacy Close When you connect to a Wi-Fi network, your ISP and others on the network can see your internet activity.This is because standard DNS requests travel in plain text.
On a public Wi-Fi network, you're also vulnerable to spoofing, where attackers can tamper with DNS responses to send you malicious login pages.By using a secure, encrypted DNS provider, you protect yourself from these attacks and can better hide your network activity.Enabling private DNS on Android is pretty straightforward.
On my Samsung S24 FE, all I had to do was go to 'connection settings' and then hit the 'more connection settings' tab, and it was right there.You can choose between three settings: Automatic, Off, and Private DNS provider hostname.Select the last option and enter the address of the provider you want to use.
We have a list of the best DNS servers for private browsing if you're not sure which one to use.Turn on randomized MAC addresses Add to the anonymity There are several reasons to make sure MAC address randomization is on, especially if you're connected to a public Wi-Fi network.Without randomization, your phone's Media Access Control (MAC) address acts as a sort of fingerprint for your device.
This makes it easy for a third party to log your movements and your behavior.A key benefit of this is that it blocks targeted profiling, making it harder for detailed databases to be built around your activity.On a lot of Android devices, this is turned on by default, but it is still something that is worth checking.
Go back into your 'Connection' settings and tap the Wi-Fi tab.Tap the gear next to the Wi-Fi network and then select 'View more'.This should bring up the MAC address type.
As long as this is set to random, you're good to go.While you're here, you can also deselect the option to have your phone or tablet send your device name to the network.Make sure you're not automatically connecting to open networks Don't just use whatever connection is available While I often avoid connecting to public Wi-Fi networks altogether, sometimes you get caught with no mobile signal, and you just need to get something done.
Generally, even if you take all the necessary precautions, you should avoid accessing any sensitive accounts on a public Wi-Fi network at all.Regardless, when I do have to use them, I make sure to turn auto-reconnect off, especially if the network is somewhere I visit often.To do this, you'll need to go back to your network settings, specifically the Wi-Fi tab.
Then tap the gear icon next to the Wi-Fi network you're connected to.You should then see a toggle for auto-reconnect.Switch this off, and then you can be sure that your device doesn't just jump back onto the network whenever you're in the area.
Sometimes you will want to meter your connection as well Don't incur any unnecessary fees Certain places I frequent offer free Wi-Fi, but they cap the amount of data you can use in a single visit.Sometimes, my phone will eat up this allowance with background apps or updates that I could otherwise get to later, when I'm connected to my home Wi-Fi network.Turning on Wi-Fi metering helps your phone limit background data usage as much as possible, so you don't burn through your allowance or incur extra charges.
You'll find the Wi-Fi metering setting in the same place as your MAC address randomization setting.You need to tap the gear icon next to the Wi-Fi network, and then hit the 'more settings' drop-down.Some modern devices can automatically detect whether a connection is metered if the network is set up properly, but doing it manually adds a little extra peace of mind.
Wi-Fi networks can leave you vulnerable to all sorts of problems The world is becoming more and more connected by the minute.As security technology evolves, third parties launching malicious attacks are becoming increasingly creative.Keeping your device, the information stored on it, and your network usage as secure as possible is becoming a necessity.
This is especially true if you often use public networks, where all kinds of hidden threats can lurk.While the above don't make you completely immune to attacks, they are settings that can definitely make you more secure.
