Locking down Development server without using IP-based Zone lock?

What is the name of the domain?

developmentservercom

What is the issue you’re encountering

difficult to keep updating the Zone Lockdown IP addresses for developers

What steps have you taken to resolve the issue?

trying to find a better way than restricting IPs which update all the time as Devs roam or use VPN

What are the steps to reproduce the issue?

I need another system to lock down our development server that is not the IP restriction zone lockdown - it is too cumbersome to always change the IPs of my developers. Is there another way to do this that is not IP-based?
