- Conditional Redirection: The code verification result can be processed with an If Then Else structure to perform different actions based on valid/invalid codes.
- Dynamic Code Source: The code can be verified by retrieving it from different sources (e.g. SMS, email, in-app message).
- One-Time Codes: The code can be generated by the system to be valid only once.
- Time Limit Warning: When the code expires, the user can be offered the option to request a new code.
Technical Risks and Controls
- Code Format Check: The user accidentally entering spaces or invalid characters can cause errors. Pre-entry validation should be performed.
- Timeout: The validity period of the code should be well defined in the system and communicated to the user.
- Privacy: Codes should not be stored in plain text in the system and should be processed using secure algorithms.
- Incorrect Code Attempts: After a certain number of incorrect entries, the user should be temporarily blocked.
The Is Verification Code Valid action enables users to securely verify their identities. It provides an effective verification step without compromising the user experience in scenarios requiring advanced security. It plays a critical role in password reset, two-factor authentication, and registration processes.
