Use LinOTP Authenticator to secure your accounts with two-step authentication by generating verification codes to access your accounts. Two-step authentication provides an extra level of security for your accounts because every new verification code generated by LinOTP Authenticator is uniquely valid for a single sign in request only. LinOTP Authenticator is compatible with most of your accounts already as it supports standard TOTP and HOTP security algorithms. However, it works best with LinOTP, the enterprise-level 2FA solution.

Verdict
The clearest difference is ads: LinOTP Authenticator at none against VPN's shown. LinOTP Authenticator also leads on iOS requirement (13.0 vs 16.0). VPN's advantage is update cadence (every 2 months vs every 8 months). On price, in-app purchases and device support there is nothing between them.
