Security Task: 2FA Setup for Critical Systems

Goal

Enable Two-Factor Authentication on administrative interfaces (e.g. Proxmox, Portainer, Git).

Examples

Proxmox (TOTP):

1. Login as user
2. Go to Datacenter → Permissions → Users
3. Add TOTP secret
4. Test backup code

Portainer:

1. Enable OAuth or SSO if available
2. Enforce MFA from the admin panel

Git (self-hosted):

• Use SSH keys for repo access
• Enforce 2FA on web interface if using GitHub/GitLab

Tools

• Authenticator apps (Aegis, FreeOTP, Google Authenticator)
• Admin panels of relevant platforms
