Two-factor authentication (2FA) - how to protect your financial data in the digital space

According to a report by www.verbraucherzentrale.de, the article is about the importance of two-factor authentication (2FA) for the security of online accounts. 2FA confirms a user's identity from two different sources and makes it harder for criminals to access personal information. In addition to well-known methods such as SMS TAN or email, there are other and more secure options for two-factor authentication that can contribute significantly to protecting personal data.

2FA is an important security measure to protect yourself from unauthorized access and identity theft. Using a second factor besides password and username makes access to online accounts much more difficult. These additional factors can be, for example, confirmation codes via email, SMS TANs, one-time passwords, biometric procedures or even hardware tokens. This means that even if you know the password, access to the account is prevented because the second factor is required. This increases security and protects against unauthorized access and misuse of personal data.

For the market, this means increased implementation of secure 2FA methods by online services and providers to ensure user security. However, these additional security measures can lead to higher costs and increased effort for companies. On the consumer side, using 2FA may require some getting used to and a willingness to take extra steps when logging in. Overall, however, 2FA contributes to increased security in the digital space and offers consumers reliable protection against unauthorized access to their accounts and personal data.
