Good fit if

  • Rolling phishing-resistant MFA out to a team.
  • It does what the deadline requires at a price that makes fifty people affordable.

Look elsewhere if

  • Anyone needing OATH codes, smart card logon or OpenPGP.
  • Those are 5 Series features and this line does not have them.

Security Key C NFC by Yubico connects over USB-C. It also works over NFC, so the same key taps against a phone.

Rolling phishing-resistant MFA out to a team. It does what the deadline requires at a price that makes fifty people affordable.

Where it is the wrong choice: anyone needing OATH codes, smart card logon or OpenPGP. Those are 5 Series features and this line does not have them.

Every order ships from Sydney with a tax invoice, and we are happy to talk through a rollout before you commit to a quantity.
