Credential hygiene is the practice of creating, storing, rotating, and protecting passwords, keys, and tokens in ways that reduce misuse and exposure. It matters because weak credential habits still enable an enormous share of real-world compromise.
What is Credential Hygiene?
Credential hygiene covers password quality, secret storage, credential rotation, MFA support, token protection, reuse reduction, and removal of exposed or obsolete authentication artifacts. It applies to both human and non-human access.
What Credential Hygiene Commonly Includes
Common practices include password managers, secret vaults, credential rotation, phishing-resistant authentication, elimination of embedded secrets, and fast response to exposed credentials.
Credential Hygiene vs. Password Policy
Password policy defines rules for passwords. Credential hygiene is broader and includes all types of secrets and how they are handled operationally.
Frequently Asked Questions
Why is credential hygiene important?
Because exposed, reused, weak, or badly stored credentials remain one of the easiest paths for attackers.
How do teams improve it?
By combining user discipline, stronger tooling, modern authentication, secure secret handling, and continuous cleanup of risky credential patterns.
