Microsoft Account App Password. Empowering your use of technology is a critical component of the account. This app password is separate from a normal password and can be set up from the security info page.
From office and windows to xbox and skype, one username and password connects you to the files, photos, people, and content you care about most. An app password is a password other than the account password that you would need when you have 2 step authentication enabled (which is a good thing) The verification request can be pushed to an authorized microsoft account app running on a trusted pc or mobile device (again, the app is only available for android devices).
However, if the user have any problems when creating a new app password, as a workaround, you can delete all of the app password this user has created and let he create a new one.
Use this app password and your email address to sign in to your email app. If you don’t use a password manager, those complex passwords can be hard to remember.if you’ve forgotten the password for your microsoft account—which might be an account at outlook.com, live.com, hotmail.com, or even skype.com—you can’t really recover that same password, but it’s easy enough to recover your account by resetting your password to something new. Email, phone, or skype name. Copy or enter the created app password in the password field to sign in, and you're all set for that app or device.
