Master your digital footprint: the right habits when starting your career

Introduction

First internship, work-study program, first job… The beginning of professional life often comes with new accounts, new tools and new digital habits. Professional email address, work software, HR platforms, social networks, online storage space: within a few weeks, the opportunities to share or let personal information circulate multiply.

In this context, protecting your data doesn't mean becoming a cybersecurity expert. A few simple habits can already limit risks and help you better control your digital footprint, that is, all the information you leave on the Internet through your activities.

Take stock of what's already visible online

Before even starting a new job, it can be useful to see what appears when you search for your own name on the Internet.

The results can reveal an old account on a social network, a profile created during your studies, a photo published years ago, or a forgotten comment on a forum. Not everything needs to be deleted, but this search helps you become aware of what is publicly accessible.

For personal accounts, also check the privacy settings and information visible to people who are not among your contacts.

The goal is not to build a perfectly polished online presence. It's mainly about knowing what information is accessible and deciding which information you actually want to make public.

Use different passwords for each account

When accounts multiply, it can be tempting to reuse the same password everywhere. However, this is a habit to avoid.

If a service's login credentials are compromised, a reused password could potentially allow access to other accounts. This rule is particularly important for email addresses, which are often used to recover access to many other services.

A password manager can make things easier. It allows you to create and keep unique passwords without having to memorize them all.

Also remember to enable two-factor authentication when this option is available. It adds a verification step when logging in and provides additional protection in case your password is compromised.

Separate personal and professional life as much as possible

Starting a career often involves juggling multiple digital environments. A good habit is to maintain a clear separation between personal and professional uses.

For example, avoid storing work documents on your personal cloud storage or using your professional email address to create accounts unrelated to your work.

This separation is also useful for electronic devices. If your company provides you with a work computer or phone, use them in accordance with the rules established by your employer. Similarly, documents containing confidential information should not be transferred to personal applications simply because they are more convenient.

These precautions protect both your own data and the data you have access to in the course of your work.

Be careful with public Wi-Fi networks

Working from a café, library or train station can be convenient, especially when you're a student, intern or working remotely. But public networks should not be used without caution for sensitive operations.

When possible, prefer using your phone's hotspot or a trusted network. For professional uses, a VPN can also help protect communications by encrypting the connection between your device and the VPN server.

However, this does not mean that a free VPN makes you anonymous or protects against all threats. It does not replace a strong password, updates, or vigilance against suspicious messages.

Don't underestimate small information leaks

Your digital footprint is not limited to publications you choose to share voluntarily. A simple photo taken at the office can sometimes reveal much more information than expected.

A visible screen in the background, a work badge, a meeting board, or a document on a desk can contain confidential data. Before posting a photo or screenshot, take a few seconds to check what appears around the main subject.

The same habit applies to CVs, portfolios and professional profiles. Avoid displaying personal information that isn't necessary, such as a complete postal address or certain details about your private life.

Learn to recognize phishing attempts

Phishing is a technique used to trick someone into communicating information or taking action: clicking a link, sharing a password, opening an attachment, or making a payment, for example.

New employees at a company may be particularly targeted by messages that appear to come from a colleague, a manager, or an internal department.

A few warning signs should catch your attention: an unusual urgent request, a link to a strange address, an unexpected attachment, or a request to share confidential information.

When in doubt, it's better to verify the request through another channel before acting. If a message appears to come from your manager, for example, you can confirm directly with them rather than replying to the original message.

Keep your devices updated

Updates are sometimes seen as merely an inconvenience, especially when they arrive at the wrong time. Yet they regularly fix security vulnerabilities.

Your computer, smartphone, browser and professional applications must therefore be kept up to date. Enable automatic updates when possible and avoid indefinitely postponing necessary restarts.

Also remember to lock your screen when you step away from your workstation, even for a few minutes. This gesture may seem trivial, but it prevents someone from easily accessing information left open.

Adopt good digital hygiene from the start of your career

Mastering your digital footprint ultimately doesn't require changing your habits. It's mainly about developing a few good habits: checking what's public, using unique passwords, enabling two-factor authentication, separating personal and professional uses, staying alert to unexpected messages, and protecting your devices.

These habits are particularly useful at the beginning of professional life, when you're discovering new tools and sometimes handling information you never had access to before.

Taking a few minutes to secure your accounts and think before sharing information can prevent many problems later on. And above all, these habits quickly become automatic: a good way to start your career with solid digital habits.

Mastering your digital footprint doesn't require becoming a cybersecurity expert.
