Google Authenticator

Google Authenticator is a security app that provides two-factor authentication (2FA) for your online accounts, adding an essential layer of protection beyond passwords. The app generates unique verification codes that you must enter alongside your password when signing in, even without an internet connection. Key features include the ability to sync authentication codes across devices through your Google Account, easy setup via QR codes, and support for multiple accounts management. The app allows both time-based and counter-based code generation and offers convenient account transfer between devices using QR codes. To implement Google Authenticator with Google services, users need to enable 2-Step Verification on their Google Account. This additional security measure helps prevent unauthorized access and account hijacking, making your online presence more secure.
