Secure log-in via two-factor authentication
Our two-factor login within mail.ch reinforces our efforts to provide you with optimal levels of security in combination with ease of use. We provide two methods of protecting the email account with a two-factor approach: The authenticator, and U2F devices.
An authenticator provides a second parameter that is required for access to your emails - the 6-digit authenticator code. This code is generated by an app that is provided for Android and iOS. The apps can be found in either the Apple AppStore (iPhone/iPad) or the Google PlayStore (Android).
U2F (Universal Second Factor)
The standardised U2F procedure requires a small device that is connected via USB or Bluetooth, and therefore ensures that only you can use the email account with this device. The U2F token can be used for other services that support this process as well as for mail.ch. U2F-capable devices can be bought from 5 CHF upwards.
