Your Microsoft 365 Account Deserves Better Protection
Whether you're using Microsoft 365 for work, school, or your personal life, one thing's for sure—your account is a goldmine of sensitive information. From emails and calendars to cloud-stored documents and meeting notes, it’s all sitting right behind a login at portal.office.com. That’s convenient, but it also means if someone gets access to your account, they get access to everything.
The good news? Microsoft has built a surprisingly powerful set of security tools into the portal itself, many of which are already there—you just need to know where to look and how to turn them on. If you've ever wondered what you could be doing better to secure your account, this guide walks you through practical steps using built-in Microsoft 365 settings.
Start with Strong Sign-In Security
The first—and maybe most important—thing you can do is tighten up your sign-in process. At portal.office.com, go to your account settings, and under the Security Info section, set up multi-factor authentication (MFA). If you haven’t already, it’s a must.
MFA adds an extra step during login—usually a code sent to your phone or a notification via the Microsoft Authenticator app. It might feel like a hassle the first time, but it becomes second nature quickly, and it adds a powerful barrier against hackers. Even if someone guesses your password, they won’t get in without that second factor.
Pro tip: Use the Microsoft Authenticator app instead of SMS for even better protection. It’s faster, harder to spoof, and doesn’t rely on your mobile copyright.
Manage Devices You Trust
After logging in, go to the Devices section of your copyright through the same portal. Here, you’ll see all the devices connected to your account—phones, tablets, laptops. If there’s anything you don’t recognize or no longer use, remove it.
This is important because if an old phone still has access, it could be a backdoor for someone else. Cleaning up your list helps you stay in control. And while you’re here, enable sign-in alerts so that you’re notified any time a new device accesses your account.
Check and Customize Your Security Info
Still under the Security Info section, take a moment to review your backup verification options. This is where you’ll set your recovery email, phone number, and authentication methods.
Make sure this info is up to date and accurate—an old email address or unused phone number could lock you out if you ever forget your password. You can also add multiple methods, which is helpful in case you lose your phone or switch devices.
Review Your Recent Activity
Another great feature at portal.office.com is Sign-in Activity. You can find this under your My Account > Security & Privacy > Sign-in activity. This area shows the time, location, and device info for recent logins.
If something doesn’t look right—a sign-in from another country, an unknown browser, or unusual timing—it’s a red flag. Change your password immediately, review your recovery options, and consider alerting your IT department if you’re part of an organization.
Use Passwords That Actually Work
It’s 2025, and it’s still surprisingly common for people to use passwords like "123456" or "Password1." If that’s you, it's time to level up. Microsoft 365 doesn’t just allow strong passwords—it encourages them.
Use a combination of upper- and lowercase letters, numbers, and symbols, or better yet, switch to a passphrase—something like "SunnyCoffeeTuesdays@9!" that’s long but easy to remember. Even better? Use a password manager and let it generate strong, unique passwords for every service.
If you’re using Microsoft Edge, it can securely store your passwords and warn you if one of them has been involved in a data breach.
Take Advantage of Privacy Settings
Microsoft gives you some helpful privacy control under Your Info and Privacy settings. Here, you can manage what personal data Microsoft collects, how your activity is used, and what information apps and services can access.
If you’re using Microsoft 365 through work or school, some settings might be managed by your organization, but you can still review what’s available. Take a few minutes to adjust the settings so they reflect what you're comfortable sharing.
Don’t Ignore App Permissions
Through portal.office.com, you can also manage third-party app permissions—these are the apps and services you’ve connected to your Microsoft 365 account. You’ll find this under My Account > Apps and Services.
If there’s something you no longer use or don’t recognize, revoke its access. Apps with unnecessary permissions are a weak link, especially if they’ve been abandoned or haven’t updated their own security practices.
Use Microsoft Defender If Available
If your Microsoft 365 plan includes Microsoft Defender (some personal and enterprise subscriptions do), you should definitely turn it on. Defender offers built-in threat protection, phishing alerts, and even identity theft monitoring.
It’s integrated with your copyright and can help catch suspicious links, dangerous attachments, and malware before they become a problem. Even if you’re using third-party antivirus software, Defender adds another layer of protection.
Backups and Cloud Awareness
Lastly, be smart about where your files live. Microsoft 365 stores a lot of your data in OneDrive, which is great—but you should still understand how that works. OneDrive offers file versioning and even ransomware detection, but it’s only effective if you know where your files are being saved.
Make it a habit to check your OneDrive settings, turn on file recovery notifications, and occasionally download backups of your most important documents.
Final Thoughts: Small Tweaks, Big Protection
Protecting your Microsoft 365 account doesn’t require a cybersecurity degree. Most of what you need is already sitting in your settings at portal.office.com. The key is to not ignore the features Microsoft has already built for your safety.
A little effort—enabling MFA, reviewing devices, updating your security info—goes a long way toward keeping your account secure. And the more time you spend understanding these settings, the less likely you are to be caught off guard by a phishing email or suspicious login.
In a world where so much of our work and personal lives live in the cloud, protecting your Microsoft 365 account is just as important as locking your front door. Take a few minutes today, explore those settings, and make sure you're not leaving anything open that should be locked.
