<h1>Income Tax Department Introduces E-filing Vault for Enhanced Security with Dual-Factor Authentication Options.</h1> The Income Tax Department has launched the E-filing Vault, a new security feature for taxpayers to protect their E-filing accounts from fraudulent access. Taxpayers can enhance security by choosing higher security login methods such as Aadhaar-linked OTP, Net-Banking, or Digital Signature Certificate (DSC). This dual-factor authentication prevents unauthorized access even if login credentials are shared. Additionally, taxpayers can secure password reset processes using the same methods. Upcoming options include ATM, Bank Account, and Demat Account validations. The department advises using strong passwords and enabling the E-filing Vault for added security.
