While the Outlook.com password will be refused and you'll get a log-in error in your email client, you can set up specific Outlook.com passwords for use in email programs that work even with two-step authentication otherwise required. You can create a new POP password for each application, and if anything spurious happens, all the passwords so set up are disabled easily and fast.
Set Up Application-Specific Passwords for Accessing Outlook.com via POP
To create a new password for allowing an email program to log in to your Outlook.com account even when you have two-step verification enabled:
- Click your name or avatar in Outlook.com's top navigation bar.
- Select Account settings from the menu that shows.
- If prompted:
- Type your Outlook.com account password over Password.
- Click Sign in.
- Open the Security info category under Overview.
- Click Create a new app password under App passwords.
Use the password that appears under Use this app password to sign in in the email program as the POP password.
Disable Application-Specific Passwords in Outlook.com
To delete application passwords associated with your Outlook.com account and prevent log-in using them:
- Open your account's Security info page.
- Follow the Remove existing app passwords link under App passwords.
- All passwords you have set up for your Outlook.com account will be disabled. You cannot delete specific passwords, and will have to change the Outlook.com POP passwords in all your email program.
- Click Remove.
