# Auth

Use the `ably auth` command group to manage authentication, API keys, and tokens. These commands enable you to issue and revoke tokens, and manage API keys for your apps.

## Token management commands 

Use the following commands to issue and revoke [Ably tokens and JWTs](https://ably.com/docs/auth.md). Tokens provide short-lived, scopeable access for client-side authentication:

| Command | Description |
| ------- | ----------- |
| [`ably auth issue-ably-token`](https://ably.com/docs/cli/auth/issue-ably-token.md) | Create an Ably Token with specified capabilities. |
| [`ably auth issue-jwt-token`](https://ably.com/docs/cli/auth/issue-jwt-token.md) | Create an Ably JWT token with specified capabilities. |
| [`ably auth revoke-token`](https://ably.com/docs/cli/auth/revoke-token.md) | Revoke Ably tokens by client ID or revocation key. |

## Key management commands
