Tech How-To & Guides
Most smartphone security comes down to a handful of settings that take a few minutes each to check. None of this requires technical expertise — just twenty minutes and a willingness to actually open your settings menu instead of assuming the defaults have you covered.
1. Set a real lock screen method
A six-digit passcode is meaningfully more secure than a four-digit one, and biometric unlock (fingerprint or face) adds convenience without weakening security when it’s backed by a strong passcode as fallback. Avoid simple patterns or passcodes based on obvious dates.
2. Turn on automatic software updates
Most security vulnerabilities are patched quietly through routine software updates. Check your settings to confirm automatic updates are enabled for both your operating system and your most-used apps, so you’re not relying on remembering to update manually.
3. Review app permissions
Go through your installed apps and check which ones have access to your location, camera, microphone, and contacts. It’s common to find apps with permissions they no longer need or never needed in the first place. Revoke anything that doesn’t make sense for what the app actually does.
4. Enable two-factor authentication where it matters most
Your email account, your password manager, and your primary cloud storage account are the highest-value targets, since compromising any of them often gives access to everything else. Turn on two-factor authentication for these accounts specifically, using an authenticator app rather than SMS where the option is available, since SMS-based codes are more vulnerable to interception.
5. Check what’s visible on your lock screen
By default, many phones show message previews and notification content on the lock screen — visible to anyone who picks up your phone, even without unlocking it. Adjust notification settings to hide sensitive content until the phone is unlocked.
6. Know how to remotely locate and wipe your device
Both major mobile platforms offer a built-in “find my device” feature that can locate, lock, or erase your phone remotely if it’s lost or stolen. Confirm this is enabled now, while you have calm access to your settings, rather than trying to figure it out after your phone is already gone.
The 20-minute version
- Strong passcode + biometric unlock — 2 minutes
- Confirm auto-updates are on — 2 minutes
- Review app permissions — 8 minutes
- Two-factor on email, password manager, cloud storage — 6 minutes
- Lock screen notification privacy — 1 minute
- Confirm find-my-device is active — 1 minute
None of these steps make your phone unhackable — nothing does — but together they close the majority of realistic, everyday risks with almost no ongoing effort required.
