FIDO FIPS Security Keys

FIDO FIPS Security Keys (Device-bound passkey and FIPS 140-2/3 Validated): FIDO FIPS Security Keys are hardware authenticators that meet the NIST FIPS 140-2 cryptographic module validation requirements. They provide strong hardware-backed security and are approved for use in U.S. federal environments where AAL3 assurance is required. These keys combine phishing resistance, cryptographic protection, and compliance with federal standards.

IMPORTANT! Exostar does NOT sell the hardware key. You MUST purchase that separately.

A FIDO Security key must contain the following properties to be allowed in the Exostar product environment:
NIST Assurance Level: AAL2
FIPS 140-2/3 Validation: Must be active and listed on the NIST Cryptographic Module Validation Program
Passkey Protection: Must be hardware
Passkey Storage Location: Must be device-bound
FIDO Alliance Certification Level: Must be at least L2
Attestation: Required

Please follow the steps below to purchase a FIDO FIPS Security Key. Please visit your customer page for more information on the purchase and set-up process, as this can differ per customer depending on the proofing requirement and application access.

Step 1. Purchase FIDO Passkey License

It is important you verify with your partner which FIDO credential you require to access their applications. You can complete a purchase for the FIDO Passkey License with or without Proofing from Exostar’s web store. You must also purchase the hardware key separately as this is not currently offered from Exostar’s web store. Please see that process in Step 2. Purchase Hardware Key.

IMPORTANT! Once you successfully purchase the FIDO Passkey License, you will receive a purchase confirmation license key. This license key is used ONCE during the credential set-up process and IS NOT the same as the FIDO Passkey License, which is the credential you will use to authenticate to access your partner applications. 

To purchase your FIDO Passkey License:
1. Navigate to Exostar’s web store.
2. Select your Partner from the drop-down provided.
3. Select the radio button for FIDO Passkey License with or without Proofing (1 year, hardware key not included). Click Next.
4. Review and complete any missing information in the Primary Information and Billing Address sections. Click Next.
5. Select your Payment Method and input payment details. Click Submit to complete your purchase.
NOTE: If you select the Invoice option, Exostar must receive full payment before you receive your license key to activate your credential.

NOTE: The license key format is KEY-XXXXXXXXXXXXXXXXX.
