How to Improve Your Phone's Security Score: A Complete 2026 Guide

Your phone is a vault. It stores banking apps, personal photos, work emails, health data, location history, and access to nearly every online account you own. Yet most people carry this vault around with the digital equivalent of a broken padlock. If you've ever seen a "security score" in your phone's settings or a security app and wondered what it actually means — or how to raise it — this guide will walk you through everything you need to know.

In this article, we'll break down what a phone security score is, why it matters, and share 15+ practical steps to improve your phone security score across both iPhone and Android devices.

What Is a Phone Security Score?

A phone security score is a numerical rating (usually 0–100) that reflects how well your device is protected against common threats like malware, unauthorized access, data theft, and privacy leaks. Both iOS and Android now offer built-in "Safety Check" or "Security Checkup" features, and third-party apps like Bitdefender, Norton, and Google Play Protect assign similar scores.

The score typically weighs factors such as:

Operating system and app update status
Screen lock strength (PIN, password, biometrics)
Two-factor authentication (2FA) coverage
App permissions and installed apps from unknown sources
Network security settings (Wi-Fi, Bluetooth, encrypted DNS)
Backup and encryption status
Privacy controls (ad tracking, location sharing)

A low score doesn't mean you've been hacked — it means you're an easier target. Raising it makes you a harder one.

Why Your Phone Security Score Matters in 2026

Mobile threats have grown more sophisticated. According to recent industry reports, mobile phishing attacks ("smishing"), malicious apps, and SIM-swap fraud incidents have all increased significantly year-over-year. Your phone is now the primary attack surface for identity theft.

A strong security score correlates directly with:

Financial safety — banking and payment apps stay protected
Identity protection — reduced risk of account takeover
Privacy preservation — fewer apps and trackers harvesting your data
Peace of mind — you know your device is actively defended

How to Check Your Current Phone Security Score

Before improving your score, you need a baseline. Here's how to find it:

On iPhone (iOS 17+)

Open Settings → Privacy & Security
Tap Safety Check to review sharing, access, and account status
Check App Privacy Report for tracker activity

On Android (14+)

Open Settings → Security & privacy
Look for the Security status dashboard at the top
Tap each yellow or red warning to see recommended actions

Third-Party Tools

Apps like Bitdefender Mobile Security, Norton 360, and Kaspersky offer detailed scoring with remediation steps. They can be useful as a second opinion but choose reputable vendors only.

15 Steps to Improve Your Phone Security Score

Below are the highest-impact changes you can make today. Most take under two minutes each.

1. Update Your Operating System Immediately

OS updates patch known vulnerabilities. Enable automatic updates: Settings → General → Software Update (iOS) or Settings → System → System update (Android). Delayed updates are one of the top reasons security scores drop.

2. Update Every App

Outdated apps often carry unpatched bugs. Open the App Store or Google Play, go to your profile, and update everything. Turn on auto-updates for apps too.

3. Use a Strong Passcode — Not Just Biometrics

Biometrics are convenient but fall back to your passcode. A 4-digit PIN can be brute-forced. Switch to a 6+ digit numeric code or, better, an alphanumeric passphrase.

iOS: Settings → Face ID & Passcode → Change Passcode → Passcode Options
Android: Settings → Security & privacy → Screen lock

4. Enable Two-Factor Authentication Everywhere

2FA is arguably the single most impactful security upgrade. Use an authenticator app (Google Authenticator, Authy, or 1Password) rather than SMS whenever possible, since SMS is vulnerable to SIM-swap attacks.

5. Audit App Permissions

Most apps request far more access than they need. Revoke unnecessary permissions:

Location: change to "While Using" or "Ask Next Time"
Microphone & Camera: disable for apps that don't need them
Contacts and Photos: use limited access whenever offered

6. Delete Unused Apps

Every installed app is a potential vulnerability. If you haven't used it in 90 days, delete it. Both iOS and Android now offer "offload unused apps" features.

7. Turn On Automatic Cloud Backups (Encrypted)

Backups protect you from ransomware and device loss. Enable iCloud Backup with Advanced Data Protection (end-to-end encryption) on iOS, or Google One Backup on Android.

8. Use Encrypted DNS

Encrypted DNS (DNS-over-HTTPS or DNS-over-TLS) prevents your network provider from seeing which sites you visit. Both iOS and Android support it natively:

iOS: Settings → General → DNS (via a profile from Cloudflare 1.1.1.1 or NextDNS)
Android: Settings → Network & internet → Private DNS → set to 1dot1dot1dot1.cloudflare-dns.com or dns.nextdns.io

9. Disable Ad Tracking

Turn off personalized advertising IDs to reduce data harvesting:

iOS: Settings → Privacy & Security → Tracking → Disable "Allow Apps to Request to Track"
Android: Settings → Privacy → Ads → Delete advertising ID

10. Be Careful With Shortened Links

Shortened URLs are convenient but can hide malicious destinations. Use a reputable shortener that offers preview features and scans for malware. Platforms like Lunyb include link safety features that help you identify what you're clicking before you land on the page. For more on choosing a trustworthy shortener, see our 2026 buyer's guide.

11. Turn Off Bluetooth and Wi-Fi When Not in Use

Open radios are attack vectors. Use Airplane Mode in public places if you don't need connectivity, and forget public Wi-Fi networks after using them.

12. Enable "Find My" and Remote Wipe

If your phone is lost or stolen, remote lock and wipe are lifesavers. Enable Find My iPhone or Find My Device and confirm they're actually working by signing in on another device.

13. Use a Password Manager

Reused passwords are catastrophic. A password manager (iCloud Keychain, Google Password Manager, 1Password, Bitwarden) generates and stores unique credentials for every account. This alone raises most security scores substantially.

14. Enable Lockdown Mode (High-Risk Users)

iOS Lockdown Mode drastically limits attack surfaces for journalists, activists, and executives. Android has similar hardened profiles. Enable only if you face targeted threats — it disables some conveniences.

15. Review Connected Accounts and Devices

Sign out of old devices from your Apple ID, Google Account, Meta, and banking apps. Review connected third-party apps ("Sign in with Google/Apple") and revoke access for anything you no longer use.

iPhone vs Android: Security Score Comparison

Both platforms are capable of achieving excellent security scores, but they weight things differently. Here's a quick comparison:

Security Factor	iPhone (iOS 17+)	Android 14+
Default encryption	Full-device, always on	Full-device, always on
App vetting	Strict App Store review	Play Protect + sideloading risk
Update speed	Fast, uniform across devices	Varies by manufacturer
Permission granularity	Very high	Very high (14+)
Advanced protections	Lockdown Mode, Advanced Data Protection	Enhanced Safe Browsing, Advanced Protection Program
Anti-tracking	App Tracking Transparency	Privacy Sandbox (rolling out)

Common Mistakes That Lower Your Security Score

Even security-conscious users fall into these traps:

Delaying updates because they're inconvenient
Using SMS 2FA when authenticator apps are available
Granting "Always" location access to apps that only need it occasionally
Installing apps from unknown sources or unofficial app stores
Clicking on shortened links from unknown senders without previewing them
Reusing passwords across sites
Ignoring security warnings from the OS about weak passwords or breached accounts

Advanced Tips to Push Your Score Higher

Once you've handled the basics, these advanced steps will get you into the top tier:

Use a Hardware Security Key

YubiKey or Google Titan keys provide phishing-resistant 2FA and can be used for high-value accounts like email and financial services.

Enroll in Google's Advanced Protection Program

If you use a Google account, this program adds hardware-key 2FA, restricts third-party app access, and adds extra scanning for malicious downloads.

Turn On Apple's Advanced Data Protection

This extends end-to-end encryption to iCloud Backup, Photos, Notes, and more — categories Apple previously held keys for.

Segregate Personal and Work Data

Android's work profile and iOS's Focus modes let you isolate accounts and apps, reducing cross-contamination if one is compromised.

Regularly Review Login Activity

Check the security dashboards of Google, Apple, Microsoft, and major social platforms monthly. Suspicious logins should be terminated immediately.

How Often Should You Review Your Security Score?

A quarterly review is a good baseline for most users. High-risk professionals (journalists, executives, activists) should review monthly. Set a recurring calendar reminder — a security score isn't a set-it-and-forget-it metric because new apps, permissions, and threats appear constantly.

Frequently Asked Questions

What is a good phone security score?

Anything above 85/100 is considered strong, and 95+ is excellent. Below 70 means you have significant gaps that need addressing — usually missing updates, weak authentication, or excessive app permissions.

Do I need a paid security app to improve my phone's security score?

No. Both iOS and Android have robust built-in security features that, when properly configured, will get you to a high score. Paid apps can add features like breach monitoring and web-filtering, but they're not required for a strong baseline.

Can shortened URLs hurt my phone security?

Yes, if they hide malicious destinations. Malicious shorteners are frequently used in phishing campaigns. Always use trusted shortening services that scan destinations, and consider using a link preview tool before clicking unfamiliar shortened URLs.

Is jailbreaking or rooting my phone bad for my security score?

Absolutely. Jailbreaking (iOS) or rooting (Android) disables core security protections, and most security scoring tools will flag your device as compromised. It also voids most manufacturer security guarantees and blocks certain banking apps from running.

How do I know if an app is safe to install?

Stick to the official App Store or Google Play. Check the developer's reputation, read recent reviews, review the permissions requested, and look up the app on independent security databases. If an app asks for permissions unrelated to its function, avoid it.

Final Thoughts

Improving your phone's security score isn't about paranoia — it's about closing easily exploited gaps. Most of the steps above take minutes but pay off for years. Start with the essentials: update your OS, enable strong 2FA, audit permissions, and clean out unused apps. Then work through the advanced tips as you have time.

Your phone holds more of your life than any device you've ever owned. Treating its security score as a priority — not an afterthought — is one of the smartest habits you can build in 2026 and beyond.
