Your Microsoft account is more than email and Office files. For many people it is the inbox that can reset a bank password, the login tied to a payment method, and the recovery address for other accounts. Checking it regularly is a small habit that protects real money.
The good news is that Microsoft makes it easy to see who has accessed your account and from where. Here is exactly how to check, what to look for, and how to extend that same care to the accounts where your finances live.
How to check your Microsoft account activity
Start at account.microsoft.com and sign in with your Microsoft email and password. This is your account dashboard, where you can review security, devices, and billing in one place.
To see recent sign-ins, go to the Security section and select Review activity, or visit account.microsoft.com/security directly. The Recent activity page shows when and where your account was used over the last 30 days.
You can expand any entry to see the location, the type of device, and how the account was accessed, whether by a browser, a phone, or an app. This is the fastest way to spot a login that is not yours.
What to look for on the activity page
Scan for anything unfamiliar. An unexpected city, country, or device is the clearest warning sign that someone else has your password. Microsoft groups these under an Unusual activity section when it detects them.
If you see an Unusual activity entry, expand it and choose This was me or This wasn't me. Marking something as not you prompts Microsoft to help you secure the account right away.
If you only see a Recent activity section with no Unusual activity flag, you generally do not need to confirm anything. Still, it is worth a quick look so you know what normal activity looks like for you.
How to secure the account if something looks wrong
If you spot a sign-in you do not recognize, act quickly. Go to your security settings, change your password to something strong and unique, and sign out of all devices so any intruder is kicked off.
Then turn on two-step verification. This adds a second check, such as a code from an authenticator app, so a stolen password alone will not let anyone in. Review your recovery email and phone number while you are there to make sure they still belong to you.
The reason this matters so much: if your Microsoft inbox is connected to your bank, that inbox is a master key. Anyone who controls it can request password resets and intercept the codes that protect your money.

No credit repair feature
Because your email can unlock so much, monitoring beyond the inbox is wise. Creditship, a partner, offers free credit monitoring that alerts you to new inquiries or accounts on your credit file. If a compromised email leads to identity theft, those alerts can warn you early, before the damage spreads.
Why your email account guards your money
Think about how password resets work. You click forgot password, and a link or code lands in your email. Whoever controls that inbox can take over almost any account linked to it, including banking and credit cards.
That makes your primary email the single most important account to secure. A strong, unique password and two-step verification on your Microsoft account protect far more than your messages.
It also pays to keep your financial accounts on a separate, well-guarded email if possible. Spreading the risk means one compromised login does not hand over everything at once.
Check the rest of your account dashboard
While you are in account.microsoft.com, review two more areas. Under Devices, confirm every listed device is yours and remove any you no longer use. Under Payment options, check that no unfamiliar cards or charges have been added.
These sections are easy to overlook, but they are where a quiet intruder can do financial harm. An unexpected payment method or a strange device is a red flag worth acting on immediately.
Protect the bank accounts behind your email
Securing your Microsoft login is step one. Step two is making sure the financial accounts it could unlock are guarded too, with their own strong passwords, two-factor authentication, and real-time alerts.
Instant alerts close the gap between a fraudulent charge and your awareness of it. Current Banking, a partner, sends a notification on every transaction, so an unauthorized charge appears on your phone in seconds. That speed gives you a real chance to freeze the card and dispute the charge before more damage is done.

Make it a routine
Checking your Microsoft account once is good. Doing it on a schedule is better. Set a reminder to review recent activity every couple of months, and check it right away if you get an unexpected sign-in alert from Microsoft.
Pair that with the same review on your other key accounts. A short, repeatable routine catches problems while they are small and easy to fix.
What checking cannot do on its own
The activity page shows only what Microsoft can see. A determined attacker who already changed your settings might hide their tracks, and the page will not tell you about breaches on other companies' servers.
So treat the check as one layer, not the whole defense. Unique passwords, two-step verification, breach monitoring, and transaction alerts work together. No single tool covers every gap.
Your next step
Sign in at account.microsoft.com today and open your Recent activity page. If everything looks familiar, turn on two-step verification and confirm your recovery details so the account is harder to take over later.
Then apply the same care to your bank and credit accounts. Locking down the email that controls your money is one of the highest-value security moves you can make in a few minutes.
Frequently Asked Questions
How do I check my Microsoft account activity?
Sign in at account.microsoft.com, open the Security section, and select Review activity, or go to account.microsoft.com/security. The Recent activity page shows when, where, and how your account was accessed in the last 30 days. Expand any entry for details.
How can I tell if someone else accessed my Microsoft account?
Look for an Unusual activity section or any sign-in from an unfamiliar location or device on the Recent activity page. Expand the entry and choose This wasn't me if you do not recognize it, then change your password and sign out of all devices.
Why does my Microsoft account matter for my finances?
If your Microsoft email can reset passwords for your bank or cards, it acts as a master key. Anyone who controls that inbox can take over linked financial accounts, which is why a strong password and two-step verification are essential.
What else should I do to protect my money?
Use unique passwords, turn on two-factor authentication, monitor your credit file for new accounts, and set up transaction alerts on your bank and cards. These layers catch fraud early. Terms and conditions apply to partner services.
