What type of authorization is this called? 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.īut as of today both are very secure methods and most users would prefer keeping both for convenience. 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. Yubikey 5 NFC has a 32 account limit for OTP provided I use the Yubico Authenticator App? 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.
