Understanding FASTag account login: username, password, OTP and portal access

Your FASTag account, such as the Bajaj Finance FASTag, is accessed via a secure online portal or mobile app. To log in, you typically require a username and password. Some platforms also allow login using your registered mobile number and an OTP (One-Time Password). These credentials help you:

  • Monitor your FASTag balance and transaction history.
  • Link multiple FASTags under one account.
  • Update personal details or vehicle information.
  • Recharge your FASTag conveniently.

Why it matters: Keeping your login credentials secure is crucial to prevent unauthorised access and potential misuse of your account. If you suspect any issues with your login details, it is essential to act promptly.

Step-by-step guide for first-time login and for credential reset/change

If you are logging into your FASTag account for the first time or need to reset your credentials, follow these steps:

For first-time login:

  1. Visit the official Bajaj Finance FASTag portal or download the mobile app.
  2. Enter your registered mobile number and vehicle details as prompted.
  3. Verify your identity using the OTP sent to your registered mobile number.
  4. Set a secure username and password for future logins.

For resetting or changing credentials:

  1. Go to the login page on the portal or app.
  2. Click on the "Forgot Password" or "Reset Credentials" option.
  3. Enter your registered mobile number and verify the OTP.
  4. Set a new password or update your username as required.

Pro Tip: Use a strong password that combines letters, numbers, and special characters to enhance security.
