Free Password Breach Checker India — Is Your Password Leaked?

Yes, completely safe. PhishGuard uses the k-Anonymity model developed by Have I Been Pwned (HIBP). Your password is hashed locally using SHA-1, and only the first 5 characters of that hash are sent to the API. The actual password never leaves your device. The API returns a list of matching hash suffixes and the check happens entirely in your browser.

Have I Been Pwned (HIBP) is a free service created by security researcher Troy Hunt that aggregates data from hundreds of known data breaches. It contains over 12 billion compromised credential records. PhishGuard queries the HIBP Pwned Passwords API to check if your password appeared in any known breach — without ever sending your actual password to any server.

Major Indian data breaches include JusPay (2020, 100M+ card records), BigBasket (2020, 20M user records), MobiKwik (2021, 100M claimed), Domino's India (2021, 180M order records), Air India (2021, 4.5M passengers), boAt (2024, 7.5M customers), and ixigo (2024, 7M users). If you had accounts on these platforms, your email and password may be in circulation on dark web markets.

Act within the hour: (1) Change the breached password immediately on every site where you used it. (2) Enable two-factor authentication (2FA) on your banking, email, and UPI apps. (3) Check your recent bank and UPI transaction history for unauthorised activity. (4) If the breach involved financial data, call your bank's helpline and consider a temporary transaction block.

A strong password for Indian financial accounts should be at least 16 characters long, contain a mix of uppercase letters, lowercase letters, numbers, and symbols, and should never include your name, mobile number, date of birth, or Aadhaar number. Use a passphrase like 'Coffee-River-Mountain-47!' — long, memorable, and extremely difficult to crack with dictionary or brute-force attacks.

Yes — password complexity does not protect against phishing. A perfectly complex password typed into a fake SBI or HDFC login page goes directly to the attacker in plain text, regardless of how strong the password is. This is why checking links before clicking and verifying SSL certificates matters more than password complexity alone.

Credential stuffing is an automated attack where hackers use leaked username-password pairs from one breach to try logging into other services. If your BigBasket password was leaked and you used the same password for your Paytm or net banking account, attackers can access your financial account automatically using bots. This is the primary reason never to reuse passwords across sites.

Reputable password managers like Bitwarden (free, open-source), 1Password, and KeePass are significantly safer than reusing passwords or storing them in a notes app. They generate unique strong passwords for every account and remember them for you. Bitwarden in particular is widely used in India and has never had a significant security breach.

Two-factor authentication requires a second proof of identity beyond your password — typically an OTP sent to your mobile, a TOTP from an app like Google Authenticator, or a biometric. 2FA is the single most effective protection after a password compromise. Indian banks mandate OTP-based 2FA for transactions, but enabling app-based 2FA (TOTP) on your email and UPI accounts adds an additional layer.

PhishGuard's breach checker also accepts email addresses, not just passwords. Enter your email address to see if it appeared in any known breach. If your email was found, change the password associated with that email account immediately and enable 2FA on that email — since email is the recovery key for most other accounts including net banking.

A rainbow table is a precomputed database of password hashes that attackers use to reverse-engineer passwords from stolen hashed credential databases. Modern password hashing algorithms like bcrypt, Argon2, and scrypt add a 'salt' that makes rainbow tables ineffective. However, short or common passwords remain crackable even with salting. This is why length and uniqueness matter more than complexity.

Only if there is a specific reason — such as suspecting someone knows it, having used it on an insecure network, or if the site you use it on was compromised without public disclosure. The old advice of 'change every 90 days' has been retired by NIST security guidelines. The better practice is: use a unique password per site, enable 2FA, and check for breaches rather than rotate arbitrarily.
