1. Make sure that the correct user ID is entered.

   Note The user ID resembles jsmith@contoso.com or jsmith@contoso.onmicrosoft.com. If you're not sure what your user ID is, contact your administrator.

2. Make sure that the correct password is entered.

   Note If you're copying and pasting the password, make sure that you don't include spaces before or after the password characters.

Scenario: Forgot user ID or password

See Forgot password to sign in to Microsoft 365, Intune, or Azure.

Scenario: Your organization is using password synchronization together with the Azure Active Directory Sync tool

Perform one of the following actions:

• Have the users change their computer password.
• Reset the computer password for the users. When you reset the users' password, make sure that the User must change password at next logon check box isn't selected.

After Active Directory synchronization occurs, the users' computer password in the on-premises Active Directory Domain Services (AD DS) environment is synced to Microsoft Entra ID. The users can then log on to the computer, and sign in to Microsoft 365 by using the same password.
