"We are unable to verify your credentials"

I'm happy to hear that you were able to narrow down on a cause for the issue. Usually 0.2 seconds isn't enough to cause this sort of issue however I recommend that you check the time on all of your devices. To check the date and time settings, visit this website on each of your devices and make sure the time matches: https://time.is

If the time is off on any of your devices then you'll need to adjust it. Once this is done you can re-enable two-factor authentication for your 1Password account: Turn on two-factor authentication for your 1Password account

Let me know if you have any questions. 😊
