one-time password timing/sync bug

Hi @user101621, thanks for reaching out about this!

As a first step, I would recommend double checking whether the time on your device is accurate. Two-factor authentication is very time-sensitive, with one-time passwords having a validity period of 30 seconds. Any difference in time of day on a device could cause the behaviour you're seeing. Please head to this website and ensure the time on your device matches the one shown there: https://time.is

If you find that the time on your device is incorrect, you can synchronise the clock under your Date & Time settings, and this should get your one-time passwords working again.
