Why Should You Be Using 2FA?
What is 2FA?
Two-factor authentication (2FA for short) is a security mechanism, which requires users to provide two different authentication factors to verify themselves. Its purpose is to add an extra layer of protection of a user’s credentials and their accessible resources.
Compared with single-factor authentication (only one required authentication factor - e.g. password or passcode), 2FA provides stronger protection as the additional layer of security makes it harder for attackers to gain access - even if they manage to hack a person’s password, that’s not enough to pass the authentication check. Two-factor authentication is typically made up of users providing a password as their first factor and a second factor - authentication tokens, which can take many forms: from biometric factors to push notifications and text messages.
How does it work?
Of course the exact processes that go on behind 2FA vary from one provider to another, but the principle is more or less the same: the user enters the known information (e.g. username, password) into the login prompt and after that, the site’s server finds a match and recognizes the user. The site then brings the user to the second step, where they must prove they’re in possession of something only they can have - biometrics, ID card, security token, mobile device or something else. Upon that, the user will have to enter a one-time code that was generated during the previous step. After the user has completed both authentication steps, they are granted access to the website (or application). If the process doesn’t require a password, however, the authentication tool processes the key, which is then validated by the site’s server.
Authentication tokens
They may take the form of physical devices, such as key fobs or smart cards, or as mobile or desktop applications, which generate authentication PIN codes. These codes are known as OTPs (one-time passwords) and are generated by a server and can be recognized by the authentication app (or device) as authentic. The authentication code is essentially a short series of characters, linked to a specific device, account or user, that can only be used once.
Crypto gambling and 2FA
Since there is constant talk of cyber attacks online, there’s no such thing as too much security, especially when money is concerned. So even when it comes to gambling with crypto, opt for as much security as possible! Trustdice offers a 2FA method to add that extra layer of security. If you haven’t, we strongly recommend setting it up - in order to keep your account and the acquired winnings safe.
