Two-Factor Authentication: Is It Actually Worth the Friction?

A password alone, no matter how strong, protects against one thing: someone not knowing your password. Two-factor authentication protects against the far more common real-world scenario where a password has already been compromised, through a data breach, a phishing attempt, or simple reuse across sites, and an attacker is trying to use it.

The second factor, a code from a phone, a hardware key, means a stolen password alone isn't enough to get in, which closes off the majority of practical account compromise attempts.

The perceived inconvenience of two-factor authentication is usually front-loaded. After the first few logins, most people barely notice it, particularly with 'remember this device' options that limit how often the second step is actually required.

Weighed against the actual cost of a compromised account, lost data, unauthorized document access, reputational damage, the ongoing friction is genuinely minor by comparison.

Any account with access to sensitive documents, financial information, or administrative controls is a reasonable place to require two-factor authentication without exception, even if it remains optional elsewhere for lower-stakes accounts.
