Key Takeaways
- Run software updates immediately on any new device before signing into accounts.
- Set a strong screen lock using a PIN, password, or biometric method before storing any data.
- Enable full-disk encryption if it is not already active by default on your device.
- Review and restrict app permissions and default privacy settings during initial setup.
- Turn on automatic updates and device-find/remote-wipe features before everyday use begins.
Why the First Hour With a New Device Matters Most
The window between unboxing a device and using it for real tasks is your best opportunity to establish a strong security baseline. Once you start signing into accounts, storing messages, and installing apps, the complexity of locking things down grows quickly. Starting from a clean state means every protective measure you put in place covers everything that follows.
This is not about advanced or technical security — it is about a small set of foundational habits that meaningfully reduce risk for everyday users. For a broader view of how device security fits into your overall digital life, see our complete digital security foundation guide.
What you will need
Gather what you need, then work through the steps below in order. Each one builds on the last.
Device Settings App
Used to configure screen locks, encryption, privacy controls, and automatic update preferences.
Password Manager
Helps you create and store a strong, unique password for the device and any accounts you set up.
Wi-Fi Network
Required to download operating system updates and security patches during initial setup.
Keeping the Device Secure After Setup
The steps above create a strong starting point, but device security is not a one-time task. A few ongoing habits keep your protection current without much effort:
- Keep automatic updates on. Operating system and app updates frequently include security patches. Letting them run automatically closes vulnerabilities before they can be exploited.
- Audit app permissions periodically. Apps you installed months ago may retain permissions you no longer want them to have. Our annual online safety audit checklist walks through everything worth reviewing on a yearly basis.
- Use strong, unique passwords for every account. A password manager makes this practical without requiring you to memorise dozens of credentials.
- Add two-factor authentication to important accounts. Understanding how two-factor authentication works helps you choose the strongest method available.
Set a Calendar Reminder to Review Permissions
Privacy settings and app permissions drift over time as you install new software and grant access on the fly. Scheduling a 15-minute review every six to twelve months catches permissions you no longer need or never intended to grant. A consistent rhythm matters more than perfect settings on day one.

Public Wi-Fi During Setup Carries Extra Risk
Avoid completing device setup — especially account sign-ins and software downloads — over public Wi-Fi networks in cafés, airports, or hotels. These networks may not be secure, and initial setup involves transmitting credentials and downloading large files. Use a trusted home or mobile network whenever possible.
