Electronic signature (e-certificate)
What is an electronic signature?
To combat phishing, Swisscom sends its e-bills with an electronic signature (e-certificate). The signature is used like a digital signature so it shows that the e-mail has actually been sent by Swisscom.
How you can tell if the e-mail has an electronic signature:
- The digital signature is in an attachment
- It includes a security warning with the comment: “This e-mail from Swisscom has been signed.”
- The sender is: bill.swisscom.com
Examples
The way the electronic signature (e-certificate) is checked and displayed depends on the operating system you use.
Mac Mail
Microsoft Outlook
For more detailed information please consult your e-mail software manual or read the information provided by the federal government.
