Is it mandatory to perform 2FA login before cash withdrawal transactions?

Yes, it is mandatory for a merchant to perform a 2FA biometric authentication (txn_auth)prior to cash withdrawal transaction initiation. The authentication is valid for 3 minutes and withdrawal has to be initiated within this time. Post this period, another bio authentication will be required for successful cash withdrawal.

Also, note that only 1 cash withdrawal transaction can be performed after a successful 2FA biometric authentication
