Summer is a busy time, and sometimes we miss that notification from ITS that our password is expiring until it’s too late. As a precaution against this, be sure to set up alternative contact information so that you will be able to reset your password if needed.
Connect to the alternate authentication page in Office 365. You will be prompted to sign into your email account or to re-enter your credentials if you’re already signed in. Then, enter an authentication phone or email by choosing the “Set it up now” option. After entering the information, you’ll receive a verification code to enter to confirm your ownership of the alternate account. After completing the verification process(es), click Finish to save the settings.
In the event that you need to reset your password, go to Outlook Web App. Click Can’t access your account? on the sign-in page. Select Work or school account, then type your E-town email address into the ID box and enter the characters. Click Next. Select the method to receive a reset code. Enter the code sent to you and click Next. Lastly, enter your new password twice and click Finish. You will be given the new password. After it has been reset, log in to OWA with the new password. It will prompt you to change your password immediately.
