When users update their Microsoft account password, they will not be able to use that new password to authenticate at Boot Guard. They will have to continue using their old Microsoft account password to authenticate at Boot Guard, or until the user goes through "Solution 2" below to reset their passphrase.
When the customer authenticates at Boot Guard with their old Microsoft account password, they will see the following error at the Windows welcome screen;
“Incorrect password or username”
When you click “OK” the "PGP SSO" user account is displayed.
If a user is using a Microsoft account (e.g. sign in credentials that look like in Windows, changes to the password do not automatically synchronize with Symantec Drive Encryption passphrase SSO.
To enable automatic synchronize of password changes and the Symantec Drive Encryption SSO passphrase, authenticate at Windows using a local user account instead of Microsoft account. Password changes will automatically synchronize when the local user account password is changed using Ctrl+Alt+Delete.
