2. Open the Google Authenticator app.
3. Set up Google Authenticator for the accounts you want to secure. This typically involves enabling two-factor authentication (2FA) on the websites or services you use.
- On the website or service, go to your account settings or security settings.
- Look for an option related to "Two-Factor Authentication," "2FA," or "Authentication App."
- Select the option to set up 2FA using an authenticator app.
- Follow the instructions provided by the website or service to link your account with Google Authenticator. This may involve scanning a QR code or entering a secret key.
4. Once you have set up Google Authenticator for an account, the app will display a time-based one-time password (TOTP) for that account. The code changes every 30 seconds.
5. When you need to log in to the website or service, enter your username and password as usual.
6. Open the Google Authenticator app on your smartphone or tablet.
7. Find the entry for the corresponding website or service within the app. It should display the account name or a unique identifier.
8. In the Google Authenticator app, you will see a six-digit verification code for that account. This code changes every 30 seconds.
9. Enter the current verification code displayed in the Google Authenticator app into the corresponding field on the website or service's login page.
10. Complete the login process, and if the verification code is correct, you will be granted access to your account.
Repeat these steps for each website or service where you have set up Google Authenticator for two-factor authentication. Remember to keep your smartphone or tablet secure since it contains the Google Authenticator app, which is crucial for accessing your accounts with 2FA enabled.
