Change of Authorized Person: email a deactivation request with company and user identifiers, then re-register a new user. To change the Authorized Person for FLA submissions, the entity must email FLA support requesting deactivation of the current user and must provide the Company Name, User Name and the Company identifier (CIN/LLPIN/UIN); once FLA support deactivates the account, the entity may re-register a new user to designate the replacement Authorized Person.
