# registry auth

> Manage sign-ins to your marketplaces

Manage sign-ins to your marketplaces.

## Commands

### login

Authenticate with a marketplace.

**Usage**

```text theme={null}
registry auth login [options]
```

### list

List all active sign-ins.

**Usage**

```text theme={null}
registry auth list [options]
```

### logout

Sign out from a marketplace.

**Usage**

```text theme={null}
registry auth logout [options]
```

### remove

Remove stored credentials for a marketplace.

**Usage**

```text theme={null}
registry auth remove [options]
```

## Examples

```bash theme={null}
# Sign in to a marketplace
registry auth login

# List active sign-ins
registry auth list

# Sign out
registry auth logout
```

## Output and behavior

Credentials are stored in the platform keychain when available, falling back to the configuration file. `auth list` prints sign-in status without revealing credential values.
