The short version

  • Each has a real cost: Google Authenticator enabling cloud sync moves the security boundary for your 2FA codes to your Google account, so a compromised Google account can expose the same codes syncing was meant to protect.; Milestone XProtect care Plus is presented as optional but is not in practice: without it, perpetual licences stop receiving version upgrades and eventually you cannot add a current camera because your frozen version does not support it.
  • They diverge on capability: Google Authenticator covers TOTP code generation, Milestone XProtect covers Open device support.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Google Authenticator

  • Enabling cloud sync moves the security boundary for your 2FA codes to your Google account, so a compromised Google account can expose the same codes syncing was meant to protect.
  • It has no built-in backup export in a portable format, so moving away from Google Authenticator to another app usually means resetting 2FA on every individual service.
  • It lacks organisational features such as folders, search or notes that some competing authenticator apps offer for people managing many accounts.
  • There is no desktop app, so codes must be read off a phone screen when logging in from a computer.
  • If sync is off and the phone is lost without a separate backup, all codes are unrecoverable and every linked account needs its 2FA reset through account recovery.

Milestone XProtect

  • Care Plus is presented as optional but is not in practice: without it, perpetual licences stop receiving version upgrades and eventually you cannot add a current camera because your frozen version does not support it.
  • Per-device licensing means multi-sensor and multi-imager cameras consume several licences each, so a headline camera count badly understates the true licence cost of a modern design.
  • It is Windows only for servers and needs a properly designed server and storage architecture, so the software price is a fraction of a project that also needs recording servers, storage and an integrator.
  • Complexity requires trained staff or a certified integrator; organisations that install it without either end up running a large deployment on default settings and never using the features they paid for.
  • Milestone retired Kite from its portfolio in favour of Arcules from January 2025, which stranded buyers who had standardised on Kite and is a reminder that the cloud side of the portfolio has changed direction more than once.

Answered from the vendors’ own pages

Google Authenticator: Does Google Authenticator cost anything?

No, it is free with no subscription or in-app purchases.

Milestone XProtect: Is XProtect really free for small sites?

Essential+ is free for up to eight cameras with no recording time limit, but it comes with no vendor support and no multi-server capability.

Google Authenticator: Is cloud sync safe?

Google documents it as protected by your Google account security. Whether that is an acceptable trade-off versus device-only storage is debated; you can turn sync off if you prefer local-only codes.

Milestone XProtect: Are licences perpetual or annual?

Device licences are perpetual. The annual cost is Care Plus, the support and software update contract, which you need to stay on current versions.

Google Authenticator: Can I export my codes to another app?

There is no official bulk export; moving to a different authenticator typically requires re-adding each account from its setup page.

Milestone XProtect: What happens if I do not renew Care Plus?

The system keeps recording, but you stop getting version upgrades, and over a few years that blocks you from adding newer cameras.

Milestone XProtect: Who owns Milestone?

Canon. The portfolio also includes BriefCam analytics and Arcules cloud video, with Arcules replacing Milestone Kite from January 2025.
