The short version

  • Only Google Authenticator has a free tier, so it costs nothing to try first.
  • 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.; OneTrust complex usage-based pricing model with multiple meters (admin users, inventory size, daily visitors, data subjects) making total cost unpredictable

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.

OneTrust

  • Complex usage-based pricing model with multiple meters (admin users, inventory size, daily visitors, data subjects) making total cost unpredictable
  • No published pricing examples or per-unit costs; all pricing requires custom quotes
  • Each solution area uses different pricing metrics, requiring complex calculations for multi-solution purchases
  • Enterprise-only positioning (Fortune 500 focus) suggests premium pricing, discouraging mid-market or startup adoption
  • Platform complexity and multiple solution areas may result in significant implementation and ongoing costs not disclosed upfront
