Two factor authentication

I have and I have setup 2factor authentication. Usually it works great. But a few time I have experienced that the one time code does not work. I get the message that it is the wrong code. I am sure it is the right one. I then have to enter a new code 4-5 times before it accepts it. After the 4-5 code it accepts it. I am absolutely sure that it is the right codes I enter each time, but it sais that each code I try is wrong until suddenly it works. As I said it is very rare it happens but I has happened about 3-5 times since I set it up a long time ago. Any ideas why?

Best regards

    Hi @andkan7917!

    The very first thing that is worth checking is if the time is the same on all of your devices. 2FA is very time-sensitive, so any drift in time on any of your devices could cause the authenticator codes to be rejected.

    A good resource that makes it easy to check this is the following website:

    After making sure the time is the same on every one of your devices, your authenticator codes should be accepted :)

  • Hello
    Thanks for quick reply. I checked and it is the same. The mysterious thing is that it happens only on a rear occasions. Usually it works perfectly.

    Is there a specific site where this is happening?

  • no it is so strange. It just suddenly happens. Maybe 1 of 20 times. And I always get to enter at the end after trying 4-5 times. So it is not a big problem for me, more just interested in why it happens in the first place. Just wondered if you had something like this happen with others:)

    @andkan7917: I haven't seen this happen other than when the time was off I am afraid. We will keep an eye out to see if we get more reports of this ;)

  • ok thanks

    @andkan7917: The service you're trying to authenticate with may simply have very strict enforcement of code expiration. Most will have a 30-60 window on either side of each code where it will still work, and many will also allow the previous and next codes to work along with the current one as well, to avoid issues with time sync on your device.
