  • They diverge on capability: Google Authenticator covers TOTP code generation, Zscaler Internet Access covers Secure web gateway.
  • 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.

Zscaler Internet Access

  • The pricing page names two base tiers, Essentials Platform and Zscaler Platform, plus modular add ons including three Digital Experience Monitoring tiers, but publishes no dollar figures anywhere and routes buyers to a demo request for cost
