Auth0 uses several cryptographic functions that depend on the system clock.
If you are running Auth0 on an IaaS (Infrastracture as a Service) provider (e.g. AWS, Microsoft Azure, etc.), time synchronization is managed automatically and you can skip these instructions.
If you are running Auth0 on your own hardware or a VM host, the PSaaS Appliance must have NTP configured correctly. In most cases, the NTP server is your Domain Controller. Contact your IT administrator for details.
The NTP server address can be changed in the configuration section of the Dashboard:
Enter either the IP address or the DNS name of the NTP server.
Auth0 uses ntpd for internal time synchronization. As described in the ntpd documentation, to change the various configuration parameters from the default settings, enter these on the same line after the NTP server address.
For example, the following settings will increase the frequency of updates:
1.south-america.pool.ntp.org burst iburst minpoll 3 maxpoll 5
If the virtual-machine hosting software, such as VMware, has an option for the host operating system (OS) to update the guest OS, this must be turned off so that the host will not interfere with the NTP time synchronization of the guest PSaaS Appliance.
For example, in VMware Tools, the "sync guest time with host" checkbox must be unchecked (off) for the Auth0 guest virtual machine.
