Goodbye passwords, hello real security: why Brazil is late in passwordless authentication

The Wall Street Journal has only confirmed what security leaders have been feeling for years: relying on passwords as the main protection mechanism is to keep a door open. Passwordless is no longer the future. It is the criterion that separates mature companies from organizations that still operate on the basis of improvisation.

When the password turns its biggest vulnerability

Billions of credentials have already been stolen. Social engineering is more refined than ever. And hashes are broken in minutes. Even so, many Brazilian companies still bet on “strong” password policies, those that no one remembers, everyone notes and the attacker thanks.

  • The more complex the rule, the more fragile the behavior.
  • The higher the rotation, the higher the cost with resets.
  • Result: security theater. Nice on paper, useless in practice.

Passwordless migration requires more than technology

Adopting modern authentication is admitting that the previous model failed, and it cost dearly. Leading companies have already evolved to native biometrics, hardware keys and context-based authentication. But without access governance, it's just changing the type of gap.

If the company does not know how many accounts there are, who has high privileges, where there are SoD (Segregation of Functions) conflicts and if each access has traceability, biometrics turns only a flaw, and a disguised operational risk.

Passwordless without GRC is an expensive illusion

What almost no one says: real security depends on real governance. Role Mining, SoD Discovery and continuous access analysis are foundation, not complement. At Vennx, that's the starting point. First, we map and validate accesses. Then, we apply modern authentication with full visibility of who enters, where they enter and why.

The world has changed. Your governance too?

NIST, CISA and Brazilian regulators have already made it clear: traditional passwords are not enough in critical environments. Who anticipates, reduces risk and cost. Whoever waits for the incident... pays more.

Passwordless is inevitable. But it is not for those who still depend on Excel.
