OTP authentication is usually required for the transaction, which ensures that only the authorized account holder has access to the money.

• The Recovery of Accounts. If an account holder loses their password or is blocked from their accounts, OTP could be utilized to aid in the process of restoring their account. By sending an one-time password to the registered email address or mobile number banks are able to verify the identity of the user and aid in the password reset process in a secure manner.

• Two-Factor authentication (2FA): OTP is frequently used as part two-factor authentication (2FA) method, in which users need to provide an item they are familiar with (e.g. the password) and a physical item (e.g. phone, mobile phone) to gain access to their accounts. This multi-layered method improves security and minimizes the threat of unauthorised access.

• Secure messaging: banks can make use of OTP for secure messaging or other notifications to customers, for example notifications about activity on their accounts transactions, transaction confirmations, or promotions. By confirming the identity of the receiver by using OTP banks can be sure that confidential information is transmitted in a secure and reliable manner.

• Online Account Opening: When opening a brand new financial account with a bank or applying for specific services in the financial sector online, OTP may be required to confirm the identity of the person applying and stop identity theft as well as fraudulent applications.
