Your e-mail account login is one of several passwords which you need to set up with Swisscom. For security reasons, it must be different from your Swisscom Login.
If you would like to change the login for your e-mail account or have forgotten it, you will first of all need to log into the Swisscom customer centre (with the Swisscom Login, the other password). There you can make the changes or view your e-mail account details.
If you would like to work with Webmail in your Internet browser, you need to log into Webmail with your Swisscom Login, not with your e-mail account login details. Then you can use your e-mail account (@bluewin.ch or @bluemail.ch) on any computer with an Internet connection.
Passwords can so quickly be deciphered by criminals using sophisticated techniques, so be sure to use secure passwords to protect your online data.
