E-Mail ID Silver (DV) | SwissSign
A data security specialist by Swiss Post

Main section

Please note: SwissSign must implement a new standard for e-mail certificates, the S/MIME BRG. As a consequence, SwissSign will have to generate the password to protect your key in case of provider-side key generation. In addition, the message confirming possession of the e-mail address is now only valid for 24 hours. The new requirements were implemented on 24 July 2023.
