Tax e-filing lockout risk after five failed login attempts

What reduces the risk. The simplest safeguard is using the net banking login option. If the taxpayer's bank supports it, they can bypass the e-filing password entirely. The bank's own authentication replaces the portal's password check, removing the lockout risk.

Another option is using a Digital Signature Certificate or Aadhaar OTP as a secondary factor. But those require prior setup. If the account is already locked, none of these alternatives work until the lock expires or the account is manually unlocked.

What makes it worse. Enabling the e-filing Vault's higher security adds a second-factor authentication step. That extra layer can block access if the user loses access to the configured method, such as the mobile number linked to Aadhaar. The portal allows login through other pre-configured methods like bank account EVC or DSC, but only if those were set up before the Vault was enabled.

A compromised account presents a more serious risk. The guidelines advise reporting the incident to cybercrime authorities or local police immediately. Changing the password at the earliest possible moment is recommended, even if the account is still accessible.

The bottom line. The five-attempt lockout is a mechanical risk, not a security breach. But for a taxpayer with a filing deadline approaching, it can cause real disruption. The simplest fix is to use net banking login or keep the password manager handy.
