Security keys typically have no moving parts and are durable, so you’ll probably use the same keys for many years. This means that they support more applications and websites, and it suggests that they are less likely to need replacing. Future-proof support for multiple standards: We focused on keys supporting the newest set of specifications, such as FIDO2.Security protocols: Since hardware keys are a security item, we dug into each company’s track record on previous recalls and looked at whether the company had a coordinated vulnerability-disclosure program to allow security researchers to report bugs.For key sizes over 2048 bits, GnuPG version 2.0 or higher is required. This application implements version 2.0 of the OpenPGP Smart Card specification which can be used with GnuPG. On Windows, the smart card functionality can be enhanced with the YubiKey Smart Card Minidriver. This application provides a PIV compatible smart card. Accessing this applet requires Yubico Authenticator. The YubiKey 4 series can hold up to 32 OATH credentials and supports both OATH-TOTP (time based) and OATH-HOTP (counter based). The U2F application can hold an unlimited number of U2F credentials and is FIDO certified. The OTP applet contains two programmable slots, each can hold one of the following credentials: All of the applications are available through this interface. The YubiKey 4C Nano uses a USB 2.0 interface. Note: Some software such as GPG can lock the CCID USB interface, preventing another software from accessing applications that use that mode. The YubiKey 4C Nano has five distinct applications, which are all independent of each other and can be used simultaneously. If you're looking for setup instructions for your YubiKey 4C Nano, see.

Note: This article lists the technical specifications of the YubiKey 4C Nano.
