# Consul Login

Command: `consul login`

Corresponding HTTP API Endpoint: [\[POST\] /v1/acl/login](/api-docs/acl#login-to-auth-method)

The `login` command will exchange the provided third party credentials with the
requested auth method for a newly minted Consul ACL token. The companion
command `consul logout` should be used to destroy any tokens created this way
to avoid a resource leak.

The table below shows this command's [required ACLs](/api#authentication). Configuration of
[blocking queries](/api-docs/features/blocking) and [agent caching](/api-docs/features/caching)
are not supported from commands, but may be from the corresponding HTTP endpoint.

| ACL Required |
| ------------ |
| `none`       |
