Google Authenticator

Google Authenticator provides a Time-based One-time Password (TOTP) that enables users to authenticate themselves in Okta.

Admins add Google Authenticator to the list of accepted authenticators in Okta. Then, users who select it to authenticate are prompted to enter the time-based, six-digit code they see in the Google Authenticator app in Okta.

Okta enforces a rate limit on unsuccessful authentication attempts from Okta-enrolled third-party OTP authenticators. These authenticators include Google Authenticator, Symantec VIP, and YubiKey OTP. The rate limit is a total of five unsuccessful attempts from any or all of these authenticators within a rolling five-minute period. When a user exceeds the rate limit, they can’t sign in until the rate limit passes. These attempts are registered in the System Log.

The Google Authenticator app allows a time difference on the end-user device of up to two minutes earlier or later than the time in the Google Authenticator app.

This authenticator is a possession factor, fulfills the requirements for user presence, and is device-bound. See Multifactor authentication.
