Traefik DigestAuth Documentation	Traefik Proxy's HTTP DigestAuth middleware restricts access to your services to known users. Read the technical documentation.

The DigestAuth middleware grants access to services to authorized users only.

Configuration Options

Field	Description	Default	Required
users	Array of authorized users. Each user must be declared using the name:realm:encoded-password format. The option users supports Kubernetes secrets. (More information here)	[]	No
usersFile	Path to an external file that contains the authorized users for the middleware. The file content is a list of name:realm:encoded-password. (More information here)	""	No
realm	Allow customizing the realm for the authentication.	"traefik"	No
headerField	Allow defining a header field to store the authenticated user.	""	No
removeHeader	Allow removing the authorization header before forwarding the request to your service.	false	No

Passwords format

Passwords must be hashed using MD5, SHA1, or BCrypt. Use htpasswd to generate the passwords.

users & usersFile

• If both users and usersFile are provided, they are merged. The contents of usersFile have precedence over the values in users.
• Because referencing a file path isn’t feasible on Kubernetes, the users & usersFile field isn’t used in Kubernetes IngressRoute. Instead, use the secret field.

Kubernetes Secrets

On Kubernetes, you don’t use the users or usersFile fields. Instead, you reference a Kubernetes secret using the secret field in your Middleware resource. This secret can be one of two types:

• kubernetes.io/basic-auth secret: This secret type contains two keys—username and password—but is generally suited for a smaller number of users. Please note that these keys are not hashed or encrypted in any way, and therefore is less secure than the other method.
• Opaque secret with a users field: Here, the secret contains a single string field (often called users) where each line represents a user. This approach allows you to store multiple users in one secret.
