How to Check If Someone Is Using Your Instagram Account (Step-by-Step Security Guide)

Have you ever had that sudden thought — what if someone else is using my Instagram account?
Maybe your account feels different, your password was shared with someone earlier, or you’re just worried about your account security.

The good news is: Instagram gives you clear tools to check this — and you can secure your account without stress.

In this guide, you’ll learn how to check if your Instagram account is hacked or being used by someone else, and how to fix it immediately.

Signs Someone Might Be Using Your Instagram Account

Before we go into the steps, watch out for these red flags:

Login alerts you didn’t trigger
New devices or locations you don’t recognize
Password change emails you never requested
Sudden logout from your own account
Changes to email or phone number

If you notice any of these, follow the steps below.

Step 1: Check Instagram Login Activity

Instagram allows you to see all devices logged into your account.

How to check login activity:

Open the Instagram app
Go to your profile
Tap the three lines (☰) in the top-right corner
Open Accounts Center
Tap Password and Security
Select Where You’re Logged In

Here, Instagram shows:

Device type
Location
Login time

👉 If you see an unknown device or location, it means someone else might be using your account.

Step 2: Check Security Emails From Instagram

Instagram sends emails whenever:

A new device logs in
Someone tries to change your password
Your email or phone number is updated

What to do:

Open your email inbox
Search for emails from Instagram
Check the activity mentioned

🚨 If you see an email you didn’t trigger, change your Instagram password immediately.

Step 3: Log Out Unknown Devices (Active Sessions)

Instagram lets you log out remotely from suspicious devices.

How to log out:

Go back to Where You’re Logged In
Find the unknown device
Tap Log Out
Immediately change your password

🔗 Reset Instagram Password (Official Link):

This ensures no one can log back in using old credentials.

Step 4: Enable Two-Factor Authentication (2FA)

Two-Factor Authentication is one of the strongest protections for your Instagram account.

Even if someone gets your password, they cannot log in without a verification code.

How to enable 2FA:

Go to Accounts Center
Open Password and Security
Tap Two-Factor Authentication
Choose:
- SMS
- WhatsApp
- Authenticator app (like Google Authenticator)

✅ This adds an extra security layer to your account.

Step 5: Run Instagram Security Checkup

Instagram also provides a Security Checkup feature.

What to check:

Go to Accounts Center
Open Password and Security
Tap Security Checkup
Verify:
- Email address
- Phone number

⚠️ These are your recovery options.
If someone changes them, they can lock you out of your own account.

Always keep them updated.

How to Protect Your Instagram Account Permanently

Follow these best practices:

Never share your password
Use a strong, unique password
Enable Two-Factor Authentication
Check login activity regularly
Monitor Instagram security emails

Final Thoughts

By checking login activity, monitoring your emails, logging out unknown devices, and enabling two-factor authentication, you can be confident that your Instagram account is safe and only yours.

A few minutes of checking today can save you from losing your account tomorrow.
