Two-Factor Authentication for Crypto Accounts: Why It Isn't Optional

Two-factor authentication is consistently recommended for crypto accounts, but it's worth understanding what it protects against rather than treating it as a box to tick during sign-up.

What Two-Factor Authentication Does

Two-factor authentication (2FA) requires a second piece of proof beyond your password to log in or authorise sensitive actions, typically a time-limited code from an authenticator app. This means that even if someone obtains your password, through a data breach, phishing, or a reused password from another site, they still can't access your account without that second factor.

Why Passwords Alone Aren't Enough

Passwords get compromised more often than people expect, through phishing pages that look identical to a real login screen, data breaches at unrelated services where the same password was reused, or malware that logs keystrokes. Two-factor authentication doesn't prevent your password from being stolen, but it stops a stolen password alone from being enough to get in, which is the more meaningful protection.

App-Based Authenticators vs SMS Codes

Authenticator apps generate codes locally on your device and are generally considered more secure than SMS-based two-factor authentication, since SMS codes can be intercepted through SIM-swapping attacks, where an attacker convinces a mobile carrier to transfer your phone number to their device. If a platform offers a choice, an app-based authenticator is the stronger option.

Setting Up Two-Factor Authentication on Bitval

Two-factor authentication is available on Bitval and should be enabled as one of the first things you do after creating an account, well before you fund it or place any trades. This applies regardless of how much you plan to keep on the platform, since the setup cost is minimal compared to the protection it adds.

Why This Matters More for Exchanges Specifically

An exchange account often sits at the intersection of your funds and your identity verification documents, making it a higher-value target than many other online accounts. Treating two-factor authentication as optional on a crypto exchange account carries more downside than skipping it on a lower-stakes account elsewhere.

Tou can create a Bitval account and secure it with two-factor authentication from the start.
