1. Enable two-factor authentication (2FA)

Two-factor authentication (2FA) is a security feature that adds an extra layer of protection to your online accounts. It requires you to enter not only your password but also a unique code that is sent to your phone or email every time you log in. This typically involves receiving a code on another device or through SMS. This way, even if someone steals your password, they won’t be able to access your account without the code.

You should turn on 2FA for any account that contains sensitive or personal information, such as your email, social media, banking, or shopping accounts. By doing so, you can prevent hackers from stealing your identity, money, or data. 2FA is especially important when you are using public or shared devices, such as computers in a library or cafe, where your password could be easily compromised. 2FA can also help you recover your account if you forget your password or lose access to your device. For both iPhones and Android phones, enabling 2FA is straightforward.

For iPhone:

Navigate to Settings
Tap on your Apple ID (your name) at the top of the screen
Select Sign-In & Security (or Password & Security in iOS 16 or earlier)
Tap Turn on Two-Factor Authentication and Continue
You'll be asked to enter a phone number where you want to receive verification codes. This can be your iPhone number. After you enter it, you'll receive a code to type in.

8. Download only trusted apps

Only download apps from official app stores such as Google Play Store or the Apple App Store.

This can help you identify any potential issues with the app, such as privacy concerns.

9. Activate spam filters for text messages

10. Invest in protective screens and cases

It's important to take both digital and physical precautions to keep your smartphone safe and secure. One simple way to do this is by using protective screens and cases. These can help your device last longer and better withstand everyday wear and tear.

Protective Screens:

Apply a tempered glass screen protector to guard against scratches and cracks.
Choose a privacy screen protector to limit the viewing angle of your screen.

Protective Cases:

Invest in a durable, shock-absorbent phone case to cushion against accidental drops.
Opt for cases that cover ports and buttons to keep dust and debris from damaging your device.

Bonus tip

If you want to go the extra mile toward keeping your phone secure, think about how and where you use Wi-Fi and Bluetooth or charge your device. Cybercriminals can use open connections to gain unauthorized access to it.

For Wi-Fi and Bluetooth:

Disable Wi-Fi and Bluetooth when not in use.
Avoid auto-connecting to open Wi-Fi networks.
Consider using a Virtual Private Network (VPN).
Turn off Bluetooth in crowded places to minimize the risk of unauthorized connections.

For charging:

Use only trusted chargers and cables.
Avoid charging your smartphone at public charging stations.
Consider using a power-only USB cable or a secure charging USB adapter when charging from unknown sources.
Public charging stations and untrusted cables may pose data theft or malware risks.
Using your own charger and cable or opting for a power-only cable minimizes these risks and helps keep your device secure.
