TOTP not working on windows with european summer time

Today the time in many counties in central europe got set to CEST (at least in germany).
Suddenly totp generated on windoes differ from the ones generated in ios and do not work anymore (the ones generated on ios do still work).
Can anyone confirm this behavior or is it a think only occuring to me?

    Hi @Dzhaguu!

    Make sure the time changed properly on your Windows machine after the change to CEST. 2FA is very time-sensitive, so any drift in time on any of your devices could cause the authenticator codes to be rejected, and I remember seeing this happen in Windows in the past when the time changed.

    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.

    Please let me know if this worked!

  • Oh...
    I'm sorry yea the cclock of my windows machine actually did not change by itself...
    now everything works fine.
    Thank you verry much...
