Password Policies Are Not Enough: What Modern Auth Looks Like

Forcing complex passwords with special characters was the standard security advice for years, but it addresses a smaller share of real-world account compromises than most people assume.

Credential stuffing is the bigger threat

Most account takeovers today come from reused passwords leaked in unrelated breaches, not from someone guessing a weak password. Strong password rules don't protect against a password the user reused from a site that got hacked elsewhere.

Multi-factor authentication is now the baseline

Requiring a second factor — an authenticator app, not just SMS which has its own vulnerabilities — blocks the vast majority of automated account takeover attempts, even when a password is compromised.

Rate limiting and anomaly detection matter

Detecting and slowing down repeated failed login attempts, and flagging logins from unusual locations or devices, catches attacks that password strength alone never will.

Passwordless is gaining ground for good reason

Magic links and passkeys remove the weakest link entirely — the reused, guessable password — while often improving the user experience at the same time.
