An app password is a code that gives an app or device permission to access your Office 365 account. You only need to set up an app password once on any device, unless your Office 365 account is deleted from the device. 

Please note:

If you are using the native Mail app on your Android device, you will have to enter an app password for your phone. If you use the Microsoft Outlook Web App (OWA) on your phone, you will not have to generate an app password for your Android device.

Creating an app password

1. Sign into Office 365 at

2. Click on the little gear settings icon and choose Office 365 settings (picture A). Note that if you are already in your Lesley email or another Office 365, you will find the Office 365 settings under Your App settings section (picture B).



3. Choose Security & privacy from the menu on the left, then click on Additional security verification. Note that you'll only see this option if your account has been set up for multi-factor authentication.

4. Choose Update my phone numbers used for account security.

5. Choose App Passwords at the top of the page.

6. Press the create button to generate an app password.

7. You will be prompted to name your app password. Name it something that describes the device on which you will be using the app password, such as Samsung phone. Press next.

8. Choose copy password to clipboard and press close.

Please note: If you have generated an app password for a different device than the one on which you generated the app password, you should save the password into a Notepad, Word, etc. document, or just jot it down. Then you can manually enter the app password to the device for which the password was intended. Under no circumstances should you email yourself the password!

9. Go to the device (or app) that you want to connect to your Office 365 account. When prompted to enter a password, paste the app password in the box.
