How To Change Password In Microsoft 365: Step-By-Step Security Guide

Changing your Microsoft 365 password feels like it should be one-click simple. Between you and me, Microsoft hides it behind a few too many menus.

I’ve walked dozens of users through this in my Denver Five Points tech center. The path differs slightly if you’re an admin versus regular user, but both take under 2 minutes once you know where to look.

You’ll find the option buried in account settings, not the obvious security tab. The process forces a sign-out everywhere, which is actually a security win most don’t realize they need.

Works the same whether you’re on Windows, Mac, or mobile. Here’s the exact path.

Step-by-Step Instructions for Changing Your Microsoft 365 Password

This process keeps your account secure and takes less than five minutes to complete.

Open your preferred browser and navigate to the Microsoft 365 login page. Enter your current email address and password to sign in. If you’re already signed in, skip this step and proceed directly to the next.

Verify you’re in the correct account by checking the profile icon or name in the top-right corner. This prevents accidentally changing the wrong account’s password, which is a common oversight when managing multiple profiles.

Once signed in, click on your profile icon in the top-right corner of the screen. From the dropdown menu, select My account. This redirects you to the Microsoft account management page.

On the left-hand sidebar, locate and click Security. If you don’t see this option immediately, ensure you’re on the Account tab, not the Home or Subscriptions tab. The security section is where all password-related changes are managed.

Under the Security tab, find the Password security section. Click the Change password link. Microsoft may prompt you to verify your identity for security purposes.

Complete the verification process, which typically involves entering a code sent to your registered email or phone number. This step is non-negotiable and ensures that only you can make changes to your account.

On the password change page, enter your current password in the first field. This confirms your identity once more before allowing any changes. Next, create a new password that meets Microsoft’s requirements: at least 8 characters, including uppercase letters, lowercase letters, numbers, and symbols.

Type the new password again in the confirmation field to ensure accuracy. Double-check for typos—password fields are case-sensitive, and a single mistake will prevent the change from saving.

Click Save to finalize the change. Microsoft will display a confirmation message indicating that your password has been updated successfully. This message is your verification checkpoint.

Sign out of all sessions and sign back in using your new password to ensure the change took effect. If you encounter any errors during sign-in, repeat the process and ensure the new password meets all complexity requirements.

Tips and Common Mistakes

These practical insights will help you avoid common pitfalls during the process.

Account Verification: In Step 1, always double-check the profile icon before proceeding. I’ve seen too many people accidentally lock themselves out of the wrong account when managing multiple Microsoft profiles. This simple verification takes seconds and prevents major headaches.

Security Section Navigation: During Step 2, if you don’t immediately see the Security tab, ensure you’re on the Account tab—not Home or Subscriptions. Microsoft’s interface can be tricky, and this is the most common place where users get stuck.

Password Requirements: For Step 4, remember Microsoft’s strict requirements: at least 8 characters with uppercase, lowercase, numbers, and symbols. I recommend using a password manager to generate and store a truly secure password that meets all criteria.

Final Verification: After Step 5, don’t skip the sign-out and sign-back-in test. This is your only way to confirm the change worked before you really need it. Trust me, you don’t want to discover an error when you’re in a rush later.
