Description This article explains the behavior of the 'update-time' command value seen under 'config authentication setting' in the FortiGate CLI.
Scope All FortiOS.
Solution

In the FortiGate CLI under 'config authentication setting', there is a setting for 'update-time'. The value showing next to 'set update-time' indicates the last time any setting under 'config authentication setting' was modified. The value is presented in the following format: yyyy-mm-dd hh:mm:ss (year-month-day and hours:minutes:seconds):

 

FGT_3 (root) # config authentication setting

FGT_3 (setting) # show
config authentication setting
    set update-time 2026-01-02 11:01:13
end

 

Note: The 'config authentication setting' command is vdom-specific, so if VDOMs are enabled in the FortiGate, the command must be preceded by the following commands:

 

config vdom
    edit <vdom name>

 

Even if the FortiGate is rebooted, the value will still show the date and timestamp of the last time that any setting under 'config authentication setting' was modified.

 

Below is a before-and-after example of making a configuration change under 'config authentication setting':

 

Before the change:

 

FGT_3 (root) # config authentication setting

FGT_3 (setting) # show
config authentication setting
    set update-time 2026-01-02 16:20:26
end

 

After changing the value of the 'captive-portal-port' from its default value of 7830 to 7850:

 

FGT_3 (root) # config authentication setting

FGT_3 (setting) # set captive-portal-port 7850

end

 

FGT_3 (root) # config authentication setting
FGT_3 (setting) # show
config authentication setting
    set update-time 2026-01-02 16:23:39
    set captive-portal-port 7850
end

 

As seen above, the 'update-time' value was updated to the timestamp of when the 'captive-portal-port' was changed.
