2. Entering the Key: You enter this setup key into Google Authenticator during the setup process. This step links the app to your account by syncing it with the service provider’s authentication system.
3. Generating Codes: Once linked, Google Authenticator uses the setup key to generate time-based codes that you’ll use to verify your identity when logging in.
4. Unique Identifier: The setup key is a unique string of characters provided by the service you’re securing, which is entered into Google Authenticator.
