The process of authenticating oneself for access to a digital platform, typically an account, via a message delivered electronically. This message usually contains a code or link that the user must interact with to verify their identity. For instance, a platform might send a unique code to a user’s registered address, which the user then enters on the login page to complete the verification process.
This verification method enhances security by adding an extra layer of protection against unauthorized access. It mitigates the risk of account compromise, even if the password has been obtained by malicious actors. Its implementation stems from the increasing need to protect sensitive information and maintain user trust in an environment of escalating cybersecurity threats. Over time, it has become a standard security practice across various online services and platforms.
