n the digital world we live in, the confidentiality of personal data hangs by a thread. The overexposure we face and cyber attacks make information security a vital issue . In this sense, two-factor authentication is an essential tool. Let’s see what it consists of.
2FA ( Two Factor Authentication) is a security measure us to verify the user’s identity, providing two verification factors , and thus control their access to the desir website, application or resource.
It constitutes a second layer of protection . It reinforces the level of security of user accounts and personal data to the point of preventing, even in the event that an unauthoriz person obtains a user’s password (through a data breach), that person from being able to access the account without the second factor.
How does double verification work?
In general terms, these are the steps follow by the 2FA method , which may vary depending on the method finally chosen.
- Login . The user enters his/her name and first password. The system verifies the validity of the information and if the password is incorrect, the access process is stopp.
- Second factor request. Once the first password has been verifi, the system requests the second authentication factor.
- Generation and sending of the token code . Once the second factor has been enter, the system generates and sends a token code to the user through the chosen method (SMS, Email, facial recognition, etc.).
- Verification . Once the user enters the receiv code or performs the request action, the system verifies.
- Validation . Finally, if both factors are correct, the user gains access to the service or platform. If the second factor is incorrect, access thailand phone number data will be deni and the user will be inform of a login attempt. It should be not that the generat codes usually have a short lifespan (between 30 seconds and 1 minute) in order to increase system security.
Two-factor authentication: different types
This is one of the most common two-factor authentication methods.
After entering the correct password, the system automatically sends a verification code via SMS to the mobile phone number associat with the user account . Once the user enters the correct code, within the specifi 10 of the best voicemail scripts for cold calling time, he or she will gain access.
Although it is a less immiate method than the previous one, it is still very popular.
After entering the correct password, agb directory the system will request two-factor authentication by automatically sending a verification code to the email address associat with the user’s account . By entering the correct code, the user will gain access to the system.
As a weak point, it must be taken into account that the email could end up in Spam.
They represent one of the most secure and popular options for providing a second level of verification. These applications generate temporary authentication codes bas on an algorithm or allow direct approval of login requests.
Unlike SMS or email, these codes are not transmitt over external networks, making them more secure and less susceptible to certain types of attacks .
