2-factor authentication is a modern security technology that can be used to prove a person's identity. It is now used by numerous companies to better protect personal accounts and prevent unauthorized access. Financial institutions in particular are increasingly using the technology in addition to a PIN or password, but private possessions such as smartphones, laptops, etc. can also be secured using the technology.
How does 2-factor authentication work?
It is also called 2-way authentication because it is used to unlock or access a user account and consists of two authentication methods that are independent of each other. This means that another verification method is used in addition to the username and password. This can vary. For example, you can receive a code or a TAN number on the cell phone number stored in your account, which then has to be entered, or you can also have a fingerprint checked.
Some providers or companies let their users decide for themselves which second factor should be used in addition to the password. However, the use of 2-factor authentication is often still optional and not mandatory. In the end, the double protection serves the user himself.
2-factor authentication is used here
There are already a whole range of industries and companies that work with 2-factor authentication. Surely most people know it from finance. Bank accounts in particular are protected with this, at least the technology is used when an online transfer is made. Mastercard Casino for example , when you want to make a deposit with your credit card. You will be redirected to the financial institution and must confirm the payment using two independent factors. Since the security is therefore very high, the Mastercard is considered one of the most popular means of payment in digital arcades.
Another popular payment service that is present in many industries and takes advantage of this method is Paypal. If you want to make mobile payments with your Paypal account, you not only have to log in with your password, but you also have to confirm or verify your registration using an SMS code or directly via the installed app. In addition to payment providers, it is primarily service providers who contain personal and potentially sensitive data from users. These are, for example, email providers such as Yahoo and Windows and social networks such as Facebook and Twitter.
How safe is the method?
It is now known that simple passwords can be cracked relatively easily. They therefore no longer offer a high standard of security, which is why 2-factor authentication has already become the new standard for many. 2-way authentication is currently considered the most secure method for protecting unauthorized access A particularly high level of protection is provided if, for example, online payments are made using two devices. If a transfer is made on the computer and confirmed via cell phone, it is guaranteed that someone unauthorized will not find out so easily. It is very unlikely that someone will come into possession of both devices and the passwords.
To be precise, this means that it is always best to opt for confirmation via SMS code for the second authentication - if you have the choice. In principle, however, it is a really secure method to ensure the highest level of protection for personal data.
