I want to mass update username and email address for 4000+ users, and want to make sure that their username gets updated. There's only two ways to update username:
- If User go to link prompted by salesforce on username change and approve that
- If org admin generates new password for user with username update so username will be updated instantaneously.
Please suggest way (dataloader or anything) to make this change successfully without getting approval for new username from every user.
Note: New password generation is acceptable way to do so, but there are more than 4000 records so doing individually is out of scope.
