# 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](/vault/docs/auth/userpass).

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.

| Method | Path                             |
| :----- | :------------------------------- |
| `POST` | `/auth/userpass/users/:username` |

### 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 if password_hash is not given>)` - Password for the current user. Only required when creating the user.  Mutually exclusive with `password_hash`.
- `password_hash` `(string: <required if password is not given>)` - Pre-hashed password for the current user in bcrypt format. Mutually exclusive with `password`.
