For years, SMS codes felt like a solid security upgrade. Businesses moved from password-only logins to “password + SMS verification,” and for a while, that was enough to stop many simple attacks.
Today, the situation is different.
Modern cyberattacks rarely focus on brute-forcing passwords anymore. Attackers usually target people instead. Phishing campaigns, fake Microsoft 365 login pages, compromised devices, and social engineering have become much more common than traditional hacking attempts.
As a result, SMS-based authentication is starting to show its age.
It’s still better than relying on passwords alone — but for modern business infrastructure, SMS is no longer considered strong protection.
