I forgot the username or password for the account I use with Office.

This article is for people who set password expiration policy for a business, school, or nonprofit.

If you're a user, you don't have the permissions to set your password to never expire. Ask your work or school technical support to do the steps in this article for you.

User passwords expire on a regular basis in Office 365. As an admin, you can make user passwords expire after a certain number of days, or set passwords to never expire.

  1. Go to the Office 365 admin center.

    Go to the Office 365 admin center.

    Go to the Office 365 admin center.

  2. In the Office 365 admin center, go to Settings > Security and privacy:

    Navigate to Security and Privacy.

  3. Click Edit.

    Choose Edit.

  4. If you don't want users to have to change passwords, set Passwords never expire to On.

    Set to On.

  5. If you want user passwords to expire, in the first box type how often passwords should expire. Choose a number of days from 14 to 730.

    Enter how often passwords should expire.

  6. In the second box type when users are notified that their password will expire, and then click Save. Choose a number of days from 1 to 30.

    IMPORTANT: Let's say you set the value to 10. When a user signs in to Office 365 10 days before their password is set to expire, they will see a prompt that says their password is going to expire in 10 days. The next day when they sign in, it will say 9 days, and so on. No email is sent to them.

    When a user signs in to Office 365 and their password has expired, they will be prompted with a page like the one shown below to create a new password:

    Office 365 prompts the user to create a new password.

Prevent last password from being used again

If you want to prevent your users from recycling old passwords, you can do so in Azure AD. See Password policies and restrictions in Azure Active Directory

Synchronize user passwords from an on-premises Active Directory to Azure AD (Office 365)

To learn how this works and how to set it up, see Implement password synchronization with Azure AD Connect sync..
