No. Existing users of SFC2007 must explicitly request access to SFC2014 by providing their Unique identifier at the Commission (uid) to their MS Liaison.
This Unique identifier at the Commission (uid) is the same one that is used for the SFC2007 account and can be found accessing https://webgate.ec.europa.eu/cas and logging into EU Login and clicking on the gear at the top right corner to display the menu and select 'My Account' -> 'My EU Login Account Details' -> 'Unique identifier at the Commission (uid)'
Alternatively if a user already has an SFC2007 account they can login to SFC2007 and find their Unique identifier at the Commission (uid) on the top-left of the screen:
Once the access request sent by the MSL is processed users will then be able to access SFC2007 and SFC2014 with the same Username and Password.
