Best Phone Security Tips in 2025
1. Set Strong Passwords and Biometrics
Even though we always carry our phones with us, there are times when we leave it unattended. Whether you are at a party or your workspace, there are plenty of instances when you might leave your phone unattended for some time. But the problem is, you never know whom you cannot trust. Even if you leave your phone unattended for a minute, someone can snoop through your phone. So, the solution is a strong password. If you are still using a simple pattern lock or, worse, none at all, you are leaving the door wide open for intruders. Always set a strong password that contains a mix of letters and digits to ensure your Android or iPhone’s security.
But a password is not the only thing that can protect you. A better and more convenient solution is a biometric lock. An extra layer of security, biometric options, like fingerprint recognition or facial scans, cannot be unlocked without your presence. Therefore, your phone will stay completely secure.

2. Control App Permissions
Whenever you install an app, it asks for permissions. In most cases, we do not read about the permissions properly. We just breeze through these requests and grant all the permissions it asks for. They ask for access to your location, camera, contacts, and even microphone. While it is perfectly normal, you must be careful about the apps you are giving permissions. Otherwise, you might end up giving any unknown app access to your private information.
Since all the apps you download from the Google Play Store and Apple App Store are completely secure, you do not have to worry about them. Just be careful while downloading apps from any unreliable platform. Those apps could be harmful. Also, go to your phone’s settings and review the permissions app by app at times. If anything seems suspicious, revoke that permission immediately.
In this case, iPhone’s security is better than Android’s security. Apple has blocked many apps due to security reasons and offers very limited access to your personal information.
3. Two-Factor Authentication (2FA)
Sometimes, a password is not enough to secure your phone — you need a two-factor authentication (2FA) for certain apps. It adds an extra step to your logins where you need your password as well as a secondary form of verification — a code sent to your phone. Even though it is a very small and simple process, it makes your phone significantly secure. Now, even if someone manages to hack into your phone, the person will not be able to access certain information because of it. Many services, including Google, Apple, and banks, now offer 2FA.
4. Update Software Regularly
Many of us have the habit of delaying updates. Even if we see the update notification in the notification bar, we just slide it back up and ignore it. People mostly ignore them thinking it will be an inconvenient process. However, neither the update process is inconvenient, nor should you delay it. Software updates do not just fix bugs, they also have security patches. These updates are essential to make your phone secure from hackers. So, always update your phone whenever you see a new version is available. The process occurs in the background and does not interfere with your tasks in most cases. However, in case of any major update, your device may restart.
5. Never Open Suspicious Links and Apps
We already discussed why giving permission to unknown apps can be dangerous for you. However, it is not just about giving permission all the time — your device can get compromised even if you open an app or link. This is one of the most common tricks used by scammers to hack your phone. The scam starts with the hacker sending you a text or an email containing a link. As soon as you click on it, malware is automatically downloaded on your device. It often hides it in the form of a common app that will easily go unnoticed. Over time, it will keep collecting data from your phone and sending it to the hacker. The only way to stay protected is to avoid opening emails or texts from any unknown and suspicious contact. Also, always stick to well-known app stores like Google Play or the Apple App Store.

6. Encryption
When we introduce the word ‘Encryption,’ everything suddenly starts to sound very techie. And, this is why people do not even try to fully understand this security measure. However, taking this security measure is actually quite easy. Most smartphones now come with built-in encryption features. If you just tap on it, it will scramble your data so that even if someone gains access to your phone, they cannot read whatever is inside. The only issue is that you will have to give the PIN or password every time you turn on your device or open any app.
In the event of a data breach, encryption ensures that your personal information remains unreadable.
7. Be Careful When Using Public Wi-Fi
Free Wi-Fi at cafes or airports always feels like a blessing. However, you should be careful because using public Wi-Fi has many risks. Since public Wi-Fi networks are often unsecured, it is quite easy for hackers to intercept the data you send and receive. So, always avoid public Wi-Fi whenever possible to keep your phone secure from hackers. But we understand that you have to use it at times. So, as a rule of thumb, never access sensitive accounts, such as online banking or personal emails, when you are connected to the Wi-Fi. Also, using a Virtual Private Network (VPN) is always recommended because it encrypts your internet connection.
8. Remote Wipe and Tracking Features
Losing your phone or having it stolen is a nightmare. But what will make it even worse is if someone can access the data and use it to scam you or other people. Thankfully, the companies understand this and give you the option to remotely track or wipe your device. On iPhones, you can find this feature in “Find My iPhone.” And on Androids, this feature is available under “Find My Device.” You just need a device, then log in with your details, and you can easily track your phone’s location and wipe it completely clean as well.

Frequently Asked Questions About Phone Security
1: How do I know if my phone has been hacked?
There are various signs that could indicate that your phone is hacked, however, none of them is conclusive proof. For instance, sudden battery drain and unusual data usage are indicators that your phone is hacked. If you notice apps crashing frequently or new apps appearing out of nowhere, these could also be signs of getting hacked. But other issues can also create those problems. So, if you notice any one of these issues, it does not mean that your phone has been hacked. However, you should be suspicious if you see all of these problems happening together.
2: What is the safest way to store sensitive information on my phone?
We often store sensitive information on our phones. But, storing it somewhere that is easily accessible, like notes or text messages, can be problematic. Instead, you should use password-protected apps. Check your phone settings — it will allow you to lock certain apps with passwords. Additionally, you can download third-party security apps that help in keeping information secure. Encrypted vaults or cloud-based apps are also great options because of their strong security measures.
3: How can I tell if an app is safe to download?
If you are unsure about a particular app, there is a simple solution — only trust apps from the official app store. If you are an Android user, download apps only from the Google Play Store, and iPhone users should just stick to the Apple App Store. In case you are downloading the app from somewhere else, check its reviews and ratings. It should have a high number of positive reviews and a strong developer reputation.
