What Does Google Authenticator Actually Do?
Google Authenticator generates time-based and counter-based one-time codes for compatible accounts, scans QR setup codes, imports or exports tokens, and can optionally synchronize entries through a Google Account.
Authenticator codes improve security but do not eliminate phishing, session theft, or account-recovery risk. Cloud sync adds convenience while concentrating access behind the Google Account.

Offline OTP codes
Time-based codes work without mobile data after enrollment.
QR enrollment
Camera scanning reduces manual secret-entry errors.
Account synchronization
