With an Android smartphone, you always have a mobile hotspot that you can pair with your personal computer or share with friends and family.
Not only is this handy when there is no Wi-Fi to be found, your own connection is more secure than a public hotspot for transactions like mobile banking.
However, when you are out and about using your mobile hotspot, security is important. You do not want to make it easy for someone to access your personal data from your phone or use up your data to download videos, after all.
Most Android phones can share mobile data by Wi-Fi, Bluetooth, or USB and setting up a hotspot connection on Android is easy.
Alcatel suggests some ways to secure the mobile hotspot on your Android device:
Use a secure passphrase
As much as it is tempting to use something simple and easy to remember as the passphrase needed to sign in to your mobile hotspot, you should use a complex passphrase that other people will not be able to guess. To be fully secure, consider a combination of upper and lower case letters, mixed with numbers and punctuation marks. Change this password regularly and do not share it with strangers.
Watch your screen
You will be able to see on your device when your mobile hotspot is active and how many devices are currently connected. If there are more devices using your hotspot than there should be, switch it off and change the password immediately.
Only switch the hotspot on when you need it
Rather than leaving the mobile hotspot running all the time, toggle it on when you need it and switch it off when you do not. That way, you reduce the risk of someone accessing your phone via Wi-Fi when you are not using it.
Keep your operating system up to date
You can find your device’s Android version number, security update level, and Google Play system level in your Settings app. Be sure to keep your device up to date with the latest operating system releases, since these often patch security vulnerabilities that hackers might otherwise exploit.
Note that your experience with setting up your mobile hotspot may differ, depending on the Android smartphone you use.
