===================================
FIPS 140-2 Level 1 Configuration
===================================

Without any configuration, the YubiKey 5 FIPS Series meets the requirements for the FIPS 140-2 Level 1 certification as an authenticator with FIPS-approved algorithms. Security Level 1 allows an authenticator to be used on a general purpose computing system using an unevaluated operating system. This can include computers or OSs that are configured in a FIPS-certified mode of operation, but which might not have extensive access controls or auditing features. Any function on the YubiKey may be used. The only non-approved algorithms are:

* RSA 1024-bit keys
* EdDSA keys
* X25519 keys
