Rufnummernüberprüfung

Rufnummernüberprüfung, also known as phone number verification, is a process used to confirm that a provided phone number is valid and belongs to the individual attempting to use it. This is commonly implemented by businesses and online services to enhance security and prevent fraudulent activity. The verification typically involves sending a unique code, usually a one-time password (OTP), via SMS to the registered phone number. The user then enters this code into the application or website to prove ownership. This method helps in several ways, such as preventing the creation of fake accounts, ensuring legitimate users are accessing services, and facilitating account recovery processes. Many platforms, including social media sites, banking applications, and e-commerce platforms, utilize Rufnummernüberprüfung as a standard security measure. The effectiveness of this process relies on the recipient's ability to receive SMS messages and access the provided code promptly. It is a widely adopted and relatively simple yet effective way to add a layer of authentication in digital interactions.
