Stucked in cycle of "Two-factor authentication required"

edited August 13 in iOS

I've just added Feitian U2F NFC key to my account. I tried to use it in iOS app. After I typed master password a popup with "Two-factor authentication required" has appeared. I've chosen to use the NFC security key. After success authorisation, the same popup appeared. Again I've successfully scanned my key and popup appeared again. Popup disappeared when I've chosen an authorization code. To be sure I've reinstalled the app but with the same outcome.

1Password Version: 7.6.2
Extension Version: Not Provided
OS Version: iOS 13.5.1
Sync Type:

    Looking at it appears the only devices supported on iOS are the YubiKey 5 NFC and YubiKey 5Ci.

  • Thanks for pointing this out. I wasn’t aware. :(
    Isn’t U2F an protocol that should be supported no matter which hardware you use?

    I’m really disappointed.

    We're using the Yubico SDK in order to support U2F in 1Password for iOS. The keys we can support are defined by that. Sorry. :(
