The Reckon Accounts business range desktop and hosted application currently do not have the ability to allow the Admin user to reset their password in the event that it is forgotten.
In the data file login screen there is a link indicating 'forgotten password' that simply links to an in-product help document with some suggestions and instructions to contact the Technical Support Team.
It would be very useful functionality for the Admin password to be reset either via an email to a designated admin user email address or other mechanism.
