Securing your account

You can increase the security of access to your Hosterra Email account by choosing to activate multi-factor authentication or switch to a passwordless authentication mode.

If you log in as a mailbox user, the security options are on the home page. If you log in as a domain administrator, you can access these options via the System > User Settings top menu.

Multi-factor authentication

To add a second authentication factor to your Hosterra Email account, go to your mailcow administration interface. Choose your preferred method (Yubico, WebAuth or software OTP) and follow the configuration wizard.

FIDO2

To log in without passwords (using keys), click on the Register FIDO2 device button and follow the configuration wizard.
