Why is Proton warning me that my device’s clock is wrong?

You may see a warning banner if the date and time settings on your device are more than a day in the past or future compared to the server time.

Having the correct local time set is important for security features to work properly. Several important system services, as well as your internet browser, use it to determine the validity of certificates that guarantee the legitimacy of the websites you visit. Similarly, we use the date and time to verify that keys and signatures are still valid and have not expired.

To solve this issue, please adjust your local date and time settings. If your local time settings are correct, and you believe the warning is being shown incorrectly, please contact our support team.
