What is the difference between YubiKey and Security Key by Yubico?
YubiKey 5 is our most versatile security key supporting authentication to a wide range of services and applications using not only FIDO protocols but also OTP, OATH and Smart card/PIV. It also comes in additional form factors incl. Lightning and Nano, and can be used with the Yubico Authenticator app.
The Security Key by Yubico is the more affordable option that supports FIDO2/WebAuthn and FIDO U2F protocols only. Some common services that use these are Google and Microsoft accounts, Dropbox, X, Coinbase and 1Password.
Keep your online accounts safe from hackers with the YubiKey. Trustworthy and easy-to-use, it's your key to a safer digital world.
CONVENIENT & PORTABLE: Convenient to carry and use wherever you go, ensuring secure access to your accounts at all times. Simply plug in the security key via USB-C or Lightning to authenticate.
VERSATILE COMPATIBILITY: Supported by Google and Microsoft accounts, password managers and hundreds of other popular services. Supports multiple authentication protocols including FIDO2 (hardware bound passkey), OATH-TOTP, Smart card (PIV) and OpenPGP.
DURABLE & RELIABLE: Resistant to tampering, water, and crushing. No batteries or network connectivity required, offering dependable authentication without any downtime. Manufactured in Sweden, programmed in the USA.
SPARE KEY: It's recommended to have 2 YubiKeys. By registering a secondary security key you ensure access to your accounts even if you lose your primary key.
Customers say
Customers find the security key provides great protection for email accounts and is well-made. The functionality and ease of setup receive mixed feedback - while some say it works well and is easy to set up, others report it doesn't work with all phones and find it not user-friendly. Moreover, compatibility is a concern, with several customers noting it doesn't work with Apple devices. Additionally, customers consider the product too expensive.
