Quick Tip: How to avoid expiring passwords in NSX(-T)

If you initially deploy NSX(-T) you will notice after 90 days at the latest that VMware has defined a default policy for all passwords in the environment with an expiration of 90 days. This can be quite annoying, especially in Homelab environments like mine. Therefore, in this article, I would like to briefly show you how to reconfigure the policy. Please keep in mind the security impact if you use this setting in production environments.

1. Connect to NSX(-T) Manager with SSH
2. Login as „admin“
3. Run cli commands given:
   
   get user admin password-expiration
clear user [username] password-expiration
get user admin password-expiration
   
4. Do the same on all your NSX-Managers & your NSX-Edges

Lab-NSX-Manager-01> get user admin password-expiration
Password expiration not configured for this user

Lab-NSX-Manager-01> clear user admin password-expiration
Lab-NSX-Manager-01> clear user root password-expiration
Lab-NSX-Manager-01> clear user audit password-expiration

Attention: if you have VMware Cloud Foundation, there are two KB articles (KB84190 & KB83855) that indicate there are issues with updates in Cloud Foundation when the expiration of passwords is disabled. Therefore, the setting should be different in a Cloud Foundation environment. Here the password expiration is not disabled but alternatively set to 9999.

Lab-NSX-Manager-01> set user admin password-expiration 9999
Lab-NSX-Manager-01> set user root password-expiration 9999
Lab-NSX-Manager-01> set user audit password-expiration 9999

In further tutorials, I would like to show you in the future to expand my NSX-Environment to micro-segmentation with the goal of being able to provide a multi-tenant VDI environment.
So check back here from time to time or give me feedback on what you would like to see more tutorials.
