1. Keep Your Operating System and Apps Updated
One of the simplest yet most effective ways to keep your smartphone secure in 2025 is by regularly updating your operating system and installed apps. These updates often include security patches that fix vulnerabilities hackers exploit. Whether you’re on Android or iOS, make sure auto-updates are enabled so your device stays as secure as possible.
Outdated software is a common entry point for cybercriminals, so consider updates a non-negotiable part of your smartphone hygiene.
2. Use Strong, Unique Passwords—And a Password Manager
Avoid using easily guessable passwords or repeating the same password across multiple platforms. Instead, create strong, unique passwords for each service you use. A great way to manage this without losing your mind is by using a trusted password manager.
These tools store and automatically fill in your passwords securely, making it easier to follow best practices without sacrificing convenience.
3. Enable Two-Factor Authentication (2FA)
Two-factor authentication adds an extra layer of security by requiring a second form of verification, usually via a text message, app notification, or biometric scan. This means that even if someone gets your password, they still can’t access your account.
Use an authentication app like Authy or Google Authenticator instead of relying solely on SMS-based verification, which is more vulnerable to SIM-swapping attacks.
4. Be Cautious with Public Wi-Fi
Free public Wi-Fi is convenient but often unsecured, making it easy for attackers to intercept your data. If you must connect to public Wi-Fi, be sure to use a VPN (Virtual Private Network) to encrypt your traffic.
Trusted VPN services like ExpressVPN or NordVPN can provide added protection when you’re browsing on the go.
5. Review App Permissions Regularly
Does that flashlight app really need access to your location and contacts? Review your app permissions regularly and revoke those that seem excessive or unnecessary.
Both Android and iOS allow you to manage permissions from your phone’s settings, giving you granular control over what each app can do. Avoid apps that demand access to sensitive data without clear justification.
6. Use Biometric Authentication
Smartphones today offer powerful biometric security options like fingerprint and facial recognition. These methods not only make unlocking your phone faster but also add a line of defense against unauthorized access.
Just make sure that, in addition to biometrics, you have a strong backup PIN or password in place.
7. Enable Remote Tracking and Wiping
If your smartphone is lost or stolen, you’ll want to be able to locate or erase it to protect your data. Most modern devices come with built-in tracking and remote wipe capabilities.
- For iPhones, make sure Find My iPhone is enabled.
- For Android devices, enable Find My Device.
With these tools enabled, you can locate your phone on a map, lock it, display a message, or even erase all data remotely if needed.
8. Stay Alert for Phishing and Scams
As social engineering attacks evolve, phishing remains one of the most dangerous threats to smartphone users. Be cautious of suspicious emails, texts, and links—even if they appear to come from trusted sources.
If an offer or message sounds too good to be true, it probably is. Never share sensitive information unless you’re absolutely sure the source is legitimate. For more tips on identifying phishing scams, check out the FCC’s guide to phishing awareness.
