Binance 2FA Guide
There are endless methods of hacking and circumventing password authentication through means of phishing or public WiFi, so having two-factor authentication enabled is essential to your account security.
What is 2FA?
2FA or two-factor authentication is when you protect your account with two factors or locks, creating an additional layer of security.
In this context, a factor is split into three different categories:
Users knowledge (Password)
Something the user owns (Phone)
Biometric traits (Fingerprint)
To be properly protected by 2FA your account must require 2 locks before granting access. The two main factors for Binance is a password as well as either an SMS or Google authentication code.
What are the differences between Google Authenticator and SMS authentication?
SMS Authentication
When creating an account, you provide your mobile phone number. Whenever you want to log in, the service sends you an SMS message with a verification code that expires after a certain period of time. You have to input that number in order to log in.
PRO | CON |
Convenient & Easy to use | Mobile phone numbers can be spoofed and are not as secure as Google Authentication. |
Does not require an additional application | Requires cellular reception |
Google Authentication
After setting up Google Authentication, you are assigned a backup key (secret key). The App then generates one-time passwords (OTP) at regular intervals, using the secret key as a seed. Those one-time passwords are required to log in.
PRO | CON |
Strong encryption | Losing your device means losing access to your account (unless you have a backup key) |
Doesn’t require cellular reception or wifi | Requires installing additional applications |
