Your money and personal data deserve strong protection. Punch is built with that in mind from the very first login.

How 2-Factor Authentication Works on Punch

Every time you log in, Punch checks two things:

  • Something only you know -- your 4-digit PIN

  • Something only you have -- your fingerprint (or an OTP sent to your registered mobile number)

Both factors must match before you can access your account. Even if someone knows your PIN, they cannot log in without your fingerprint or your phone.

Google Login Adds Another Layer

During registration, your account is linked to your Google login. This means your PIN and biometric data are tied to a verified Google identity, making unauthorized access even harder.

What This Means for You

  • No one can log in with just your PIN or just your fingerprint -- both are required.

  • Your biometric data stays on your device and is never shared with Punch servers.

  • Sessions expire daily, so even a stolen device with a cached session cannot be misused for long.
