## Anatomy

Parts in bold are required.

`data-scope="password-input"`: **`root`** · `label` · `control` · **`input`** · **`visibility-trigger`** · `caps-lock-indicator` · `strength-meter`

## API reference

Descriptions of individual props, events and slots are written in Chinese and appear on the Chinese page.

### Artifacts

| Layer | Value |
| --- | --- |
| Custom element | `<xh-password-input>` |
| Vue components | `XhPasswordInputCapsLockIndicator` `XhPasswordInputControl` `XhPasswordInputInput` `XhPasswordInputLabel` `XhPasswordInputRoot` `XhPasswordInputStrengthMeter` `XhPasswordInputVisibilityTrigger` |
| Composable | `usePasswordInput` |
| State machine | `passwordInputMachine` |
| Skin | `@xihan-ui/styles/password-input.css` |

### Props

| Prop | Type | Required |
| --- | --- | --- |
| `labelled` | `boolean` |  |
| `ariaLabel` | `string` |  |
| `value` | `string` |  |
| `defaultValue` | `string` |  |
| `revealed` | `boolean` |  |
| `defaultRevealed` | `boolean` |  |
| `disabled` | `boolean` |  |
| `readOnly` | `boolean` |  |
| `required` | `boolean` |  |
| `invalid` | `boolean` |  |
| `name` | `string` |  |
| `placeholder` | `string` |  |
| `autoComplete` | `string` |  |
| `strength` | `number` |  |
| `translations` | `Partial<PasswordInputTranslations>` |  |
| `variant` | `ControlVariant` |  |
| `tone` | `Tone` |  |
| `size` | `Size` |  |
| `onValueChange` | `(details: PasswordInputValueChangeDetails) => void` |  |
| `onRevealedChange` | `(details: PasswordInputRevealedChangeDetails) => void` |  |

### Events

Custom elements put the payload in `detail`; Vue emits an event of the same name.

| Event | Payload |
| --- | --- |
| `value-change` | `PasswordInputValueChangeDetails` |
| `revealed-change` | `PasswordInputRevealedChangeDetails` |

### Slots

Only slots with a payload are listed.

| Vue component | Slot | Payload |
| --- | --- | --- |
| `XhPasswordInputRoot` | `default` | `PasswordInputRootSlotProps` |
| `XhPasswordInputRoot` | `label` | — |

### React adapter props

Only the props each component declares itself: DOM attributes inherited from `ComponentPropsWithRef` are left out, and root props already listed in the Props table are not repeated. The Vue counterpart is the slot table above.

| React component | Prop | Type | Required |
| --- | --- | --- | --- |
| `XhPasswordInputRoot` | `label` | `ReactNode` |  |
| `XhPasswordInputRoot` | `children` | `SlotChildren<PasswordInputRootSlotProps>` |  |

### State

Public state is written to `data-state`.

| Part | Values |
| --- | --- |
| `visibility-trigger` | 'visible' \| 'hidden' |
| `caps-lock-indicator` | 'visible' \| 'hidden' |

The following names are internal to the state machine.

**States**: `idle`

**Events**: `VALUE.SET` · `REVEALED.SET` · `REVEALED.TOGGLE` · `CAPS_LOCK.SET` · `FORM.RESET` · `PRESS.START` · `PRESS.END`

**Guards**: `canEdit` · `canReveal`

### connect API

`getXxxProps()` returns the host attributes of the matching part.

| Member | Type |
| --- | --- |
| `value` | `string` |
| `empty` | `boolean` |
| `revealed` | `boolean` |
| `capsLock` | `boolean` |
| `disabled` | `boolean` |
| `readOnly` | `boolean` |
| `invalid` | `boolean` |
| `inputType` | `PasswordInputType` |
| `capsLockMessage` | `string` |
| `strength` | `number \| undefined` |
| `setValue` | `(next: string) => void` |
| `setRevealed` | `(next: boolean) => void` |
| `toggleRevealed` | `() => void` |
| `getRootProps` | `() => T['element']` |
| `getLabelProps` | `() => T['label']` |
| `getControlProps` | `() => T['element']` |
| `getInputProps` | `() => T['input']` |
| `getVisibilityTriggerProps` | `() => T['button']` |
| `getCapsLockIndicatorProps` | `() => T['element']` |
| `getStrengthMeterProps` | `() => T['element']` |

## Accessibility

### Keyboard

Specification: [W3C APG](https://www.w3.org/WAI/ARIA/apg/patterns/button/#keyboardinteraction). Each row is a stable behavior id that the conformance tests cover; the conditions and effects are described on the Chinese page.

| Keys | Behavior |
| --- | --- |
| `Enter` / `Space` | `password-input.kbd.toggle` |
| `CapsLock` | `password-input.kbd.caps-lock` |
| `Enter` / `Space` | `password-input.kbd.press` |

### ARIA

These attributes are produced by `connect`.

| Part | Attribute | Value |
| --- | --- | --- |
| `input` | `aria-describedby` | id of the `capsLock` part \| undefined |
| `input` | `aria-invalid` | 'true' \| 'false' |
| `input` | `aria-label` | props.ariaLabel |
| `input` | `aria-labelledby` | id of the `label` part \| undefined |
| `visibility-trigger` | `aria-controls` | id of the `password-input-input` part |
| `visibility-trigger` | `aria-label` | label.visibilityTriggerHide \| label.visibilityTriggerShow |
| `caps-lock-indicator` | `aria-atomic` | 'true' |
| `caps-lock-indicator` | `aria-live` | 'polite' |
| `caps-lock-indicator` | `role` | 'status' |
| `strength-meter` | `aria-label` | label.strengthMeter |
| `strength-meter` | `aria-valuemax` | 4 |
| `strength-meter` | `aria-valuemin` | 0 |
| `strength-meter` | `aria-valuenow` | undefined \| Math.min(Math.max(Math.trunc(rawStrength), 0), STRENG… |
| `strength-meter` | `role` | 'meter' |

## Style reference

### Skin

`@xihan-ui/styles/password-input.css` is written against `[data-scope="password-input"][data-part="root"]` part selectors; the published build uses the mount class `.xh-scope-password-input` in place of data-scope (same specificity) and sits in the `xihan.components` layer. Put overrides in `xihan.overrides`; the part selectors work as usual.

### Data attributes

Produced by `connect`; valueless attributes are omitted while their condition does not hold.

| Part | Attribute | Value |
| --- | --- | --- |
| `root` | `data-disabled` | '' (present only while the condition holds) |
| `root` | `data-empty` | '' (present only while the condition holds) |
