Nitrokey FIDO2 FAQ

Q: Which Operating Systems are supported?

Windows, Linux, and Mac OS X. Also some support (FIDO2) for Android.

Q: What can I use the Nitrokey for?

See the frontpage for an overview of supported use cases.

Q: What happens if I lose my FIDO device?

When securing accounts using FIDO (two-factor authentication and passwordless login), you should configure another factor in your account as a backup. Depending on the service this backup factor can be a phone number, an app or even a second Nitrokey FIDO2. If you lose a Nitrokey FIDO2, you can still log in with the second Nitrokey FIDO2 (or with another second factor).

Q: How large is the storage capacity?

The Nitrokey FIDO2 doesn’t contain storage capability for ordinary data (it can only store cryptographic keys and certificates).
