How to Add an Outlook.com Account in Outlook Desktop With App Password

Adding an Outlook.com account to the Outlook desktop client requires a specific authentication method when you have two-factor verification enabled on your Microsoft account. Without an app password, Outlook desktop cannot complete the sign-in process and shows a password error. This article explains how to generate an app password for your Outlook.com account and then configure it in the Outlook desktop application.

What Is an App Password and Why Outlook Desktop Needs One

An app password is a 16-character code generated by Microsoft for devices or applications that do not support modern two-factor authentication. When you enable two-step verification on your Microsoft account, the standard password alone is rejected by Outlook desktop because the app cannot process the second authentication factor such as a text message or authenticator prompt. The app password bypasses the two-step challenge while still keeping your account protected.

Outlook desktop versions from 2016 through Microsoft 365 all require this workaround when two-factor verification is active. The app password is tied to a single application and device. You cannot reuse the same app password on another computer or for another service like OneDrive. Each Outlook desktop installation needs its own unique app password.

Prerequisites Before You Start

Before generating an app password, confirm the following conditions are met:

• You have a valid Outlook.com email address with two-step verification already enabled. If two-step verification is off, you can add the account using your regular password and skip the app password steps.
• You can sign in to your Microsoft account at account.microsoft.com in a web browser.
• You have the Outlook desktop application installed and ready to configure. Outlook 2016, Outlook 2019, or Outlook for Microsoft 365 all work the same way.
• You know your Outlook.com email address and can access the associated phone or authenticator app for the two-step verification prompt.

Steps to Generate an App Password for Outlook Desktop

Follow these steps in a web browser to create an app password specifically for Outlook desktop. Do not close the browser until you have copied the app password.

1. Sign in to your Microsoft account
   Open a web browser and go to account.microsoft.com. Sign in with your Outlook.com email address and password. Complete the two-step verification prompt using your registered phone or authenticator app.
2. Open Security settings
   Click the Security tab at the top of the page. If you do not see the Security tab, click the menu icon (three horizontal lines) and select Security from the navigation panel.
3. Go to Advanced security options
   On the Security page, click the Advanced security options link. You may need to verify your identity again with a second prompt. Enter the code sent to your phone or approve the notification on your authenticator app.
4. Locate App passwords
   Scroll down to the section titled App passwords. Click the Create a new app password button or the Manage app passwords link. If you do not see this option, two-step verification may not be enabled. Go to the Two-step verification section and turn it on first, then return to this step.
5. Generate the password
   Click Create to generate a new app password. The page displays a 16-character password in a text box. Copy this password immediately. Store it in a secure location such as a password manager. You will not be able to view this password again after you leave the page.
6. Label the app password (optional)
   If prompted, enter a descriptive name such as “Outlook Desktop – Work PC” to identify which device uses this password. This helps you manage or revoke passwords later.

Steps to Add the Outlook.com Account in Outlook Desktop

With the app password copied, switch to the Outlook desktop application and add your account.

1. Open Outlook and go to Account settings
   Launch Outlook desktop. Click File in the top-left corner. On the Info page, click Add Account. If you already have an account configured and want to add a second one, click Account Settings > Account Settings > New.
2. Enter your email address
   In the Auto Account Setup dialog, type your full Outlook.com email address. Do not select the option to configure server settings manually. Outlook will attempt to detect the server automatically.
3. Paste the app password
   When prompted for a password, paste the 16-character app password you copied earlier. Do not use your regular Microsoft account password. The app password field accepts the code exactly as generated, including any hyphens if present.
4. Complete the setup
   Click Connect. Outlook validates the app password against the Microsoft servers. The process takes 10 to 30 seconds. If the password is correct, Outlook finishes the configuration and displays the account in the left navigation pane. Click Done to close the dialog.
5. Verify synchronization
   Wait for Outlook to download your email, calendar, and contacts. This first sync can take several minutes depending on the size of your mailbox. Check that the Inbox, Sent Items, and Deleted Items folders appear with your messages. Send a test email to yourself to confirm that sending and receiving work correctly.

Common Issues When Adding an Outlook.com Account With App Password

Outlook says the password is incorrect even after generating a new app password

This error occurs when you paste the app password into the wrong field or include extra spaces. Generate a fresh app password from the Microsoft account security page. Copy only the 16 characters. Paste directly into the password field without adding spaces or line breaks. If the problem persists, revoke all existing app passwords from the Advanced security options page and create a new one.

The App passwords section is missing from Advanced security options

Two-step verification must be turned on for the App passwords section to appear. Go to the Two-step verification page in your Microsoft account security settings and enable it. After activation, return to Advanced security options and the App passwords link will be visible. Generate the app password only after two-step verification is active.

Outlook keeps prompting for credentials after adding the account

This indicates that Outlook is trying to authenticate using your regular password instead of the app password. Remove the account from Outlook completely. Close Outlook and reopen it. Add the account again using the steps above, making sure to paste the app password when prompted. Also clear the Windows Credential Manager entries for Outlook and Microsoft Office to remove cached credentials that may interfere.

App password stops working after a few days

App passwords do not expire automatically, but they can be revoked if you change your Microsoft account password or reset your security settings. If the password stops working, generate a new app password from the Microsoft account page and update it in Outlook by going to File > Account Settings > Account Settings, selecting your Outlook.com account, and clicking Change. Paste the new app password in the password field.

Item	Outlook.com with App Password	Outlook.com with Regular Password
Two-step verification required	Yes	No
Password used in Outlook	16-character app password	Standard Microsoft account password
Security level	Higher with two-step verification	Lower without two-step verification
Works with Outlook 2016 and newer	Yes	Yes
Can reuse same password on multiple devices	No, each device needs its own app password	Yes, same password works everywhere
Revocation management	Revoke from Microsoft account security page	Change password to invalidate

You can now add any Outlook.com account to Outlook desktop even with two-step verification enabled. The app password method gives you the security of two-factor authentication while keeping your email client fully functional. For additional protection, review the list of active app passwords in your Microsoft account security page every few months and remove any you no longer use. If you switch to a new computer, generate a fresh app password instead of copying the old one.
