Purpose: It adds an extra layer of security by requiring a unique password for each login attempt, reducing the risk of unauthorized access. - FIDO2: Definition: FIDO2 is an open authentication standard that enables passwordless authentication using public key cryptography. Purpose: It aims to eliminate the need for passwords and enhance security by relying on biometrics or physical security keys for authentication. - FIDO U2F (Universal 2nd Factor): Definition: FIDO U2F is the predecessor to FIDO2, focusing on providing an additional layer of security through the use of physical USB or NFC tokens. Purpose: It enhances two-factor authentication by requiring both a password and a physical token for access. - OpenPGP (Pretty Good Privacy): Definition: OpenPGP is an open standard for email encryption that uses asymmetric key pairs to secure communications. Purpose: It ensures the confidentiality and authenticity of email messages by encrypting the content and providing a means to verify the sender's identity. - PIV (Personal Identity Verification): Definition: PIV is a standard for secure and reliable forms of identification, primarily used by U.S. federal agencies. Purpose: PIV cards often contain cryptographic features for secure access to physical and digital resources, serving as a form of multifactor authentication. - OATH (Initiative for Open Authentication): Definition: OATH is an organization that develops open standards for strong authentication. Purpose: OATH standards include algorithms and protocols for the generation of one-time passwords (OTP) and other forms of authentication, promoting interoperability and security in authentication mechanisms. ## Technical Specifications | Specification | Value | |---------------|-------| | Flash Memory Type | Two Factor Authentication Security Key | | Manufacturer | Yubico, Stockholm and Santa Clara, CA | | Model | 5A | | Product Dimensions | 1.8 x 4.5 x 0.33 cm; 2.83 g | | Item model number | 5A | | Flash memory type | Two Factor Authentication Security Key | | Special Features | Dust Proof | | Number of items | 1 | | Manufacturer | Yubico | | Item Weight | 2.83 g | ## Product Details - **Brand:** Generic - **Hardware Interface:** USB - **Special Feature:** Dust Proof - **Connectivity Technology:** USB - **Colour:** Black ## Images ![Yubico - YubiKey 5A - USB-A - Version 5.2.4 Two Factor Authentication Security Key - Image 1](https://m.media-amazon.com/images/I/51G4OPZOAZL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/594813048-yubico-yubikey-5a-usb-a-version-5-2-4-two](https://www.desertcart.co.uk/products/594813048-yubico-yubikey-5a-usb-a-version-5-2-4-two) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
