Vault Enterprise MFA Support

Vault Enterprise has support for Multi-factor Authentication (MFA), using different authentication types. MFA is built on top of the Identity system of Vault.

MFA Types

MFA in Vault can be of the following types.

Time-based One-time Password (TOTP) - If configured and enabled on a path, this would require a TOTP passcode along with Vault token, to be presented while invoking the API request. The passcode will be validated against the TOTP key present in the identity of the caller in Vault.
Okta - If Okta push is configured and enabled on a path, then the enrolled device of the user will get a push notification to approve or deny the access to the API. The Okta username will be derived from the caller identity's alias.
Duo - If Duo push is configured and enabled on a path, then the enrolled device of the user will get a push notification to approve or deny the access to the API. The Duo username will be derived from the caller identity's alias.
PingID - If PingID push is configured and enabled on a path, then the enrolled device of the user will get a push notification to approve or deny the access to the API. The PingID username will be derived from the caller identity's alias.

Configuring MFA Methods

MFA methods are globally managed within the System Backend using the HTTP API. Please see MFA API for details on how to configure an MFA method.

MFA Methods In Policies

MFA requirements on paths are specified as mfa_methods along with other ACL parameters.

Sample Policy

path "secret/foo" {
  capabilities = ["read"]
  mfa_methods  = ["dev_team_duo", "sales_team_totp"]
}

The above policy grants read access to secret/foo only after both the MFA methods dev_team_duo and sales_team_totp are validated.

Supplying MFA Credentials

MFA credentials are retrieved from the X-Vault-MFA HTTP header. The format of the header is mfa_method_name[:key[=value]]. The items in the [] are optional.

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --header "X-Vault-MFA:my_totp:695452" \
    http://127.0.0.1:8200/v1/secret/foo

API

MFA can be managed entirely over the HTTP API. Please see MFA API for more details.
