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.

ProtonVPN

  • Free plan limited to one device at a time
  • Free plan restricted to 10 countries with random selection
  • Pricing amounts not clearly published; shown as variable

Answered from the vendors’ own pages

Google Authenticator: Does Google Authenticator cost anything?

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

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.

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.
