Only Microsoft uses this feature right now (needed for offline 1FA/passwordless/usernameless login to Windows 10). There is no limit for regular 2FA U2F or FIDO2 accounts, but there is a limit of 25 FIDO2 resident key accounts. The Yubikey 5 NFC provides the same type of authorization as the Security Key NFC but does it have an account number limitation? What type of authorization is this called? But as of today both are very secure methods and most users would prefer keeping both for convenience. U2F is extremely hard to phish and is secured by hardware while TOTP is getting easier to phish (as hackers get smarter), with the chance of the software authenticator app's data also getting compromised. This app is created for use with the YubiKey NFC and NEO to copy One-time-passcodes (OTPs) or static passwords from a YubiKey into the iOS clipboard. SK does not support this.įor Gmail and Google, its better not to use OTP so the Security Key NFC would be good enough? YK5 can hold 32 TOTP accounts, accessed via Yubico Authenticator. provided I use the Yubico Authenticator App? Yubikey 5 NFC has a 32 account limit for OTP Yubikey 5 NFC can be used to generate one time passwords (OTP) for accounts that permit It such as Amazon, PayPal, etc. But some apps (e.g., email clients) might not support U2F, and will fall back to TOTP, SMS or an insecure "app password". Using the Security Key NFC, I no longer need to use the Google Authenticator app?įor most devices, yes. Security Key NFC can be used to log into Gmail and Google. The Security Key is a stripped down, cheaper version of it, essentially. YubiKey 5 NFC ($45) supports all the functions of the Security Key NFC ($27) and a bit more.
