• Enter the taxpayer identification number (TIN) of the provider.

Note: Every time you log in, or if you forget your password, you will be asked for a verification code to confirm it’s really you. The first time you log in, you choose how you receive verification codes. Options include a phone text or call, or authenticator app.

Multi-factor authentication, a security measure, helps prevent cybercriminals from accessing your account, even if they have your password. Here’s how it works: If you log in from an unrecognized computer or mobile phone, forget your password, or make changes to your account, or if we suspect something out of ordinary, we’ll send you a unique verification code to confirm it’s really you. You then enter that unique code, along with your username and password, to access your account.

An authenticator app is a third-party app you install on your mobile device or computer. All authenticator apps work like this: Once you open the app and choose the account you’re trying to log into, the app will generate a unique, one-time-use code to enable log in.

Authenticator apps are secure, with regularly refreshed codes unique to your device. Plus, if someone tries to gain access to your account, it’s more difficult for them to intercept your code since it’s generated by software installed on your device.

Our site has been optimized to work with the Google Authenticator app, but many other apps will work. If you wish to use Google Authenticator, here’s how to install it:

1. Open the App Store or Play Store and search for Google Authenticator (look for a multi-colored asterisk).
2. Install the Google Authenticator app.

If you wish to install another authenticator app, you may search for “install authenticator app” in your browser or in the app store you prefer.

Authenticator apps can be tied to your device, adding one more fraud deterrent. If you connect your 51�ԹϺ��� log in to an authenticator app, the codes are generated securely and only on your device. To connect your 51�ԹϺ��� log in to your authenticator, follow these steps:

3. Click the “Next” or “Continue” button on the 51�ԹϺ��� website.
