TL;DR: Credential stuffing and password reuse still drive account takeover because exposed credentials are recycled across breaches, dark web markets, and login attempts, according to Enzoic. Modern IAM hygiene now has to screen passwords at creation, login, and continuously over time without creating user friction.
Editorial analysis by NHI Mgmt Group, based on content published by Enzoic: “Block Compromised Passwords Without Breaking User Experience”.
Key questions
Q: How should security teams block compromised passwords without breaking normal login flows?
A: Security teams should check candidate credentials against a continuously updated list of known breached passwords at the moment of login and when users create or change passwords.
Q: Why do password reuse and near reuse create such high account takeover risk?
A: Password reuse turns one breach into many because attackers often test exposed credentials across multiple services.
Q: What are the signs that password blocking controls are not working as intended?
A: Warning signs include weak passwords still being accepted, inconsistent enforcement between internal and customer-facing systems, exceptions without documented CISO approval, and a lack of audit evidence showing the control was tested.
Practitioner guidance
- Screen passwords at creation and reset Check candidate passwords against breached-credential intelligence before the password is accepted, and reject known-compromised values with a user prompt to choose a different password.
- Add login-time credential verification Verify username and password pairs at authentication time so reused credentials that appear later in breach data can be blocked before a session starts.
- Monitor exposure continuously Run ongoing checks against newly discovered breach data and trigger password resets or user notifications when an account identifier appears in exposure intelligence.
Bottom line: Compromised passwords remain a practical account takeover problem because attackers reuse exposed credentials rather than breaking systems in the traditional sense.

Compromised password screening is now baseline IAM hygiene: The old model assumed password strength at creation time was enough to manage risk. That assumption fails once credentials circulate through breach marketplaces and login automation because the authentication decision happens long after the password was first chosen. The implication is that password governance has to become continuous, not point-in-time.
A few things that frame the scale:
- Password-related issues can represent 10–50% of service desk calls, many of which are avoidable.
A question worth separating out:
Q: Should organisations prioritise login-time checks or password creation screening first?
A: Password creation screening comes first because it prevents unsafe values from entering the environment, but login-time checks are the next critical layer because breach exposure often happens after a password is set. Most mature programmes need both to reduce takeover risk.
