mygreen 2FA in my.green.ch Without a Mobile Phone?

Note: Two-factor authentication (2FA) is mandatory for the my.green.ch customer portal. It cannot be completely disabled.

 

Using 2FA in the customer portal without a mobile phone

To sign in to the my.green.ch customer portal, you need a second factor in addition to your password. A smartphone is not required to use 2FA.

Depending on the available setup, you can use one of the following methods:

  • SMS to an SMS-enabled telephone number
  • Authenticator application on a computer or mobile device
  • Passkey with PIN, fingerprint or facial recognition

 

Using SMS as a second factor

A smartphone number is not required for confirmation by SMS. In principle, any telephone number that can receive SMS messages can be used.

 

Using an authenticator application on a computer

Authenticator applications are not only available for smartphones. Corresponding applications are also available for Windows, macOS and Linux.

Once set up, the application generates one-time codes that you can enter when signing in to the customer portal.

 

Signing in with a passkey

Alternatively, you can use a passkey.

A passkey uses your device’s security features for signing in, for example:

  • PIN
  • Fingerprint
  • Facial recognition

This replaces password entry and manual 2FA confirmation in a single step.

 

No longer able to access the second factor

If you no longer have access to the second factor you previously used, two-factor authentication must be reset.

First check whether you can still sign in using a device or browser that has already been saved as trusted.

Note: If you can no longer access a trusted browser or the second factor, contact Support.

 

Why is 2FA mandatory?

Two-factor authentication provides additional protection for your user account against unauthorised access.

In particular, it reduces risks from:

  • Phishing attacks
  • Stolen passwords
  • Unauthorised sign-in attempts
