Userpass Auth Method (HTTP API)

This is the API documentation for the Vault Username & Password auth method. For general information about the usage and operation of the Username and Password method, please see the Vault Userpass method documentation.

This documentation assumes the Username & Password method is mounted at the /auth/userpass path in Vault. Since it is possible to enable auth methods at any location, please update your API calls accordingly.

Create/Update User

Create a new user or update an existing user. This path honors the distinction between the create and update capabilities inside ACL policies.

Parameters

• username (string: <required>) – The username for the user. Accepted characters: alphanumeric plus "_", "-", "." (underscore, hyphen and period); username cannot begin with a hyphen, nor can it begin or end with a period.
• password (string: <required>) - The password for the user. Only required when creating the user.

• token_ttl (integer: 0 or string: "") - The incremental lifetime for generated tokens. This current value of this will be referenced at renewal time.
• token_max_ttl (integer: 0 or string: "") - The maximum lifetime for generated tokens. This current value of this will be referenced at renewal time.
• token_policies (array: [] or comma-delimited string: "") - List of policies to encode onto generated tokens. Depending on the auth method, this list may be supplemented by user/group/other values.

• token_bound_cidrs (array: [] or comma-delimited string: "") - List of CIDR blocks; if set, specifies blocks of IP addresses which can authenticate successfully, and ties the resulting token to these blocks as well.
• token_explicit_max_ttl (integer: 0 or string: "") - If set, will encode an explicit max TTL onto the token. This is a hard cap even if token_ttl and token_max_ttl would otherwise allow a renewal.
• token_no_default_policy (bool: false) - If set, the default policy will not be set on generated tokens; otherwise it will be added to the policies set in token_policies.
• token_num_uses (integer: 0) - The maximum number of times a generated token may be used (within its lifetime); 0 means unlimited. If you require the token to have the ability to create child tokens, you will need to set this value to 0.
• token_period (integer: 0 or string: "") - The period, if any, to set on the token.
• token_type (string: "") - The type of token that should be generated. Can be service, batch, or default to use the mount's tuned default (which unless changed will be service tokens). For token store roles, there are two additional possibilities: default-service and default-batch which specify the type to return unless the client requests a different type at generation time.
