Seeking Advice on Implementing RADIUS with 2FA for VPN Security

[gamser]

Hey everyone, I’m implementing RADIUS with 2FA in our organization, and I’d love to hear your thoughts on the best practices or any potential pitfalls to avoid. We’re currently using RADIUS for our VPN, and we’re considering adding 2FA to strengthen security. Anyone have experience with this?

I’ve implemented RADIUS 2FA for our VPN, and it’s been a solid security upgrade. One key best practice is to ensure your RADIUS server has proper timeout settings, especially if you’re using push notifications for 2FA, like Duo or Google Authenticator. Another tip is to thoroughly test the user experience before rolling it out company-wide; some users may struggle with the added step, so clear instructions are crucial. Also, plan for backup methods in case users lose access to their 2FA device. Overall, it’s a worthwhile investment in security.

We recently added 2FA to our RADIUS VPN setup, and it was definitely a worthwhile move for tightening up security—especially with so many remote users accessing sensitive data. One thing to keep in mind: make sure your 2FA method is user-friendly and well-documented, or your help desk will feel the strain. Compatibility between your VPN vendor and the 2FA provider also matters more than expected. I used https://www.vpnhint.net/ to compare different VPN setups and find unbiased info—it’s useful for understanding what features you actually need versus what’s just nice to have. Latency can increase slightly with 2FA, depending on your implementation, so monitor your performance before and after rollout. Also, don’t skip proper backup codes or alternate access methods. A few minutes planning now can prevent a major lockout issue later. Consider testing with a small group before going organization-wide.
