How to Fix AuthSdkError: The JWT Was Issued in the Future
Question details
The user is unable to authenticate due to a JWT timestamp error indicating the token was issued in the future.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to sign in to a Microsoft 365 or Okta-secured application where the authentication is blocked.
- Observed behavior
- The system throws an 'AuthSdkError: The JWT was issued in the future' error and denies login access.
Ensure your device is connected to an active internet network so that your operating system can successfully reach an external time server to calibrate your clock.
Enable Automatic Time Synchronization
Synchronizing your system clock with an internet time server resolves the timestamp mismatch between your device and the authentication server.
JSON Web Tokens (JWT) rely on strict timestamp validation to ensure secure authentication. If your local device clock runs even slightly behind the authentication server's clock, the server interprets the token as being generated in the future and rejects it.
On Windows, right-click the clock in your taskbar and select 'Adjust date and time'. On a Mac, open 'System Settings' and navigate to 'General' > 'Date & Time'.
Turn on the toggle switch for 'Set time automatically' (Windows) or 'Set time and date automatically' (Mac).
In Windows, click the 'Sync now' button under the 'Additional settings' section to force an immediate update with the time server.
Close your browser or the Microsoft 365 desktop application entirely, then reopen it and attempt to sign in again.
Bypass Microsoft 365 Login Issues with WPS Office
Authentication errors like 'JWT issued in the future' can lock you out of critical Microsoft 365 applications when you are on a tight deadline. WPS Office offers a reliable, lightweight alternative that allows you to create and edit documents locally without relying on continuous cloud authentication.
- 1. Download the software: Navigate to the official WPS Office website and click the free download button.
- 2. Install WPS Office: Run the installer and follow the quick setup instructions to configure the suite on your device.
- 3. Open your files: Double-click your existing Office documents to open them directly in WPS Office and resume your work.
Frequently Asked Questions
What does 'The JWT was issued in the future' actually mean?
A JSON Web Token (JWT) contains a timestamp marking exactly when it was created. If your computer's internal clock is slower or set earlier than the authentication server's clock, the server receives the token and sees a creation time that hasn't happened yet according to its own clock, causing the validation to fail.
Can a VPN cause this AuthSdkError?
Yes, occasionally. If your VPN routes your connection through a server that interferes with network time protocol (NTP) requests, your device might fail to update its clock. Disabling the VPN temporarily while syncing your clock can resolve this.
Why did my computer's clock lose synchronization in the first place?
Desynchronization can happen due to a depleted CMOS battery on your motherboard, changing time zones without automatic updates enabled, dual-booting different operating systems, or waking a computer from a long period of hibernation.
