# SafeKey as Security Key

{% hint style="success" %}
Both SafeKey One and SafeKey Pro are **plug and play devices**, so there’s not much you need to do and you can start using it without having to install any additional software or drivers.
{% endhint %}

To start using your **SafeKey One or SafeKey Pro as a security key** for [stronger two-factor authentication (2FA)](/use-cases/two-factor-authentication.md) and [passwordless logins](/use-cases/passwordless-logins.md), you need to go to your preferred services and check if FIDO2/WebAuthn is supported so you can connect your SafeKey as a security key.

This option can mostly be found via your account settings of the service you're using.

If they don't support it yet, get in touch with them and ask to integrate support for security keys so you can add an additional security layer to your account.
