How to Check Outlook App Passwords
If you need to sign in to Outlook on an older device or mail app, app passwords may be the reason your login works differently from your normal Microsoft password.
This guide explains how to check Outlook app passwords, where to look in Microsoft account security settings, and what to do if you no longer see the option.
Outlook app passwords are tied to account security features such as two-step verification, so the exact steps can vary by account type and organization policy.
Knowing where they live can save time when an email client suddenly stops connecting.
What an Outlook app password is
An app password is a special password generated for an app or device that cannot use modern sign-in methods like multifactor authentication.
Microsoft has historically used app passwords for older email clients, IMAP and POP configurations, and some desktop or mobile apps that do not support modern authentication.
In practical terms, an app password is not the same as your Microsoft account password.
It is typically longer, randomly generated, and used only in the specific app where you enter it.
- Microsoft account password: your main sign-in credential.
- App password: a separate credential for unsupported apps or devices.
- Modern authentication: the preferred sign-in method for current Outlook and Microsoft 365 apps.
How to check Outlook app passwords in a Microsoft account
For personal Outlook.com, Hotmail, or Live accounts, app passwords are usually managed from the Microsoft account security page.
You cannot always “view” an existing app password again, because Microsoft often shows it only once when it is created.
Steps to review app password settings
- Sign in to your Microsoft account security page.
- Open the Security section.
- Look for Advanced security options or More security options.
- Find the area labeled App passwords or App passwords and two-step verification.
- Check whether app passwords are enabled for your account.
If the page shows existing app passwords, you may see labels or entries for apps that were created earlier.
In many cases, Microsoft does not allow you to reveal the full password again.
If you do not remember it, the usual fix is to create a new one and replace the old value in the app that needs it.
Can you see the actual Outlook app password again?
Usually, no.
Microsoft commonly displays app passwords only at the time they are generated.
That means “checking” an Outlook app password often means confirming that one exists, identifying the app it was created for, or replacing it with a new one if needed.
This design improves security because anyone who can access the security page should not be able to casually retrieve a saved credential.
If you are trying to confirm the correct password for a mail client, test the sign-in in the app itself or create a replacement app password.
How to find app passwords in Outlook on Microsoft 365 or work accounts
For Microsoft 365, Exchange Online, or school and work accounts, app password availability depends on your organization’s security policies.
In many environments, app passwords are disabled entirely because Microsoft Entra ID and conditional access policies favor modern authentication.
If you use a work account, check with your IT administrator or help desk.
They may need to confirm whether app passwords are allowed, whether multifactor authentication is enforced, and whether the mailbox is configured for Outlook desktop, Outlook on the web, or another supported client.
- Microsoft Entra ID may block app passwords.
- Conditional Access can require modern sign-in.
- Exchange Online mailboxes often work better with current Outlook versions.
Why you may not see the app password option
If you cannot find app passwords, the account may not support them anymore.
This is common when the account uses modern authentication only or when security settings have removed legacy login methods.
Common reasons include:
- Two-step verification is not enabled, so app passwords are not offered.
- Your organization has disabled app passwords.
- You are using the new Outlook experience, which generally supports modern sign-in instead of legacy app passwords.
- The mail app already supports OAuth sign-in and does not need an app password.
If Outlook on your computer or phone is prompting for a password, first verify whether you are using Outlook.com, classic Outlook, new Outlook for Windows, or another email client.
The fix depends on the app version and account type.
How to replace an Outlook app password
If you think an app password is lost or no longer works, the safest approach is to create a new one and update the app with the new credential.
This is usually faster than trying to recover the original value.
Typical replacement process
- Open Microsoft account security settings.
- Go to the app password area.
- Create a new app password.
- Copy it carefully when it appears.
- Paste it into the email app or device that needs it.
- Remove or disable the old entry if the account page allows it.
If the app still fails after the replacement, clear saved credentials in the device’s password manager or remove and re-add the account.
How to check whether Outlook is using an app password
You may not always know whether Outlook is using your main password or an app password.
A quick sign-in error in an older mail client is often the clue.
If the account was configured before modern sign-in changes, it may still be relying on legacy authentication.
Look for signs such as repeated password prompts, connection failures after enabling multifactor authentication, or successful login only after entering a generated password instead of your normal Microsoft account password.
- Older Outlook versions may require manual account reconfiguration.
- IMAP and POP settings are more likely to need an app password.
- SMTP authentication issues can also point to legacy credential use.
Security best practices for Outlook app passwords
Because app passwords bypass some interactive security checks, use them only when necessary.
Microsoft and many IT teams recommend switching to current Outlook versions and modern authentication whenever possible.
Good security habits
- Use app passwords only for unsupported apps or devices.
- Replace them if you suspect exposure.
- Do not reuse the same app password across multiple services.
- Upgrade to a current Outlook client when possible.
- Review recent sign-ins in your Microsoft account security dashboard.
If your account supports passkeys, authenticator apps, or phishing-resistant methods, those are generally stronger than legacy app passwords.
Common troubleshooting steps when an app password fails
When Outlook keeps rejecting an app password, the issue is often broader than the password itself.
The app may be using outdated server settings or cached credentials.
Check these items first
- Confirm the email address and password were entered exactly.
- Remove stored credentials from Windows Credential Manager or the app’s saved login settings.
- Verify IMAP, POP, and SMTP server names and ports.
- Make sure SSL/TLS settings match Microsoft’s requirements.
- Update the app to the latest version available.
For Outlook desktop, sometimes the fastest fix is to remove the account and add it again.
For mobile devices, deleting the account and re-adding it can refresh authentication and server settings at the same time.
When to contact Microsoft or your administrator
Contact support or your organization’s administrator if you cannot find the app password option, the security page is missing expected settings, or your mailbox rejects authentication even after you create a new password.
In managed environments, the problem is often policy-driven rather than user error.
Useful details to share include your account type, the app name, the device model, the Outlook version, and whether two-step verification is enabled.
Those details help identify whether you need an app password, modern authentication, or a policy change.
