# 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.

<p class="callout info">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 &gt; User Settings* top menu.</p>

### Multi-factor authentication

To add a second authentication factor to your Hosterra Email account, go to your [mailcow administration interface](https://hosterra.help/books/mail-hosting/page/administration-mailcow "Administration (mailcow)"). 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.
