The Verification Step Is the New ATO Battleground in 2026

The method of account takeover, known as ATO, is changing as the traditional approach of using stolen credentials is becoming less effective. Attackers previously used automated tools to test bulk-purchased credentials, but this tactic is no longer as successful. The increased adoption of passkeys has made it more difficult for attackers to gain access using the usual methods. As a result, the verification step is emerging as a new area of focus for account takeover attempts. The shift away from traditional credential stuffing methods is underway, driven by the growing use of passkeys. This change marks the end of an era for ATO attacks, which had followed a predictable pattern for years.
