Implementing MFA on sensitive accounts is one important layer of access protection. It does not replace thoughtful identity lifecycle processes or appropriate access restrictions.
Review administrator accounts first, make phishing-resistant options available when supported, protect account recovery channels and promptly revoke access that is no longer needed.
Before buying another identity tool, review whether your existing directory and productivity suite already support these controls.
Key takeaways
- Prefer phishing-resistant MFA for high-impact accounts where supported.
- Protect account recovery and revoke access when roles change.
- Check built-in identity controls before purchasing duplicate software.

Why MFA is only one layer
A second factor can make credential theft harder to exploit, but it is not the same as complete identity security. Attackers may still exploit weak recovery procedures, excessive permissions, poorly governed service accounts, or compromised authenticated sessions. The best approach looks at the entire account lifecycle.
Start with the accounts that matter most
Identify privileged administrators, financial decision-makers, production service accounts, and accounts that can change security settings. Review who genuinely needs each permission. Prefer phishing-resistant authentication methods where the relevant service supports them, and plan carefully for recovery when a device or security key is lost.
For ordinary users, identity controls should be understandable enough to use consistently. A technically strong policy is less effective if legitimate employees repeatedly bypass it or cannot safely recover access.
Practical review questions
- Which accounts can change billing, security policies, or production systems?
- Can a compromised email inbox reset access to those accounts?
- What happens to access when someone changes roles or leaves the organization?
- Are emergency access accounts monitored, protected, and periodically reviewed?
These questions help separate the actual access risk from the number of identity products in the environment.
