A soft token, also known as a software token or an OTP (one-time password) app, is a type of multifactor authentication that generates a temporary code or password on a user’s device, such as a smartphone or a tablet. The user must enter this code or password along with their username and password to access their account or service. A soft token can help improve security by adding an extra layer of verification and preventing unauthorized access even if the user’s credentials are compromised. A soft token can also be implemented at a minimal cost, as it does not require any additional hardware or infrastructure. Biometrics, access control lists, and smart card are not types of multifactor authentication that can be implemented at a minimal cost.

Cross-site scripting (XSS) and SQL injection are common security vulnerabilities that can be mitigated by using input validation. Input validation is a technique that checks the user input for any malicious or unexpected characters or commands before processing it. XSS is an attack that injects malicious scripts into web pages to steal cookies, session tokens or other sensitive information from users or web servers. SQL injection is an attack that injects malicious SQL statements into web applications to manipulate databases, execute commands or access unauthorized data. Verified References:
