API

`OtpInput.Root`

Prop	Type	Default	Description
`value`	`string`	—	Current code, making the field controlled.
`defaultValue`	`string`	`""`	Starting code for the uncontrolled field.
`onValueChange`	`(value: string) => void`	—	Called with the code whenever it changes.
`onComplete`	`(value: string) => void`	—	Called once the code reaches the configured length.
`length`	`number`	`6`	Number of characters the code holds.
`type`	`"numeric" \| "alphanumeric"`	`"numeric"`	Which characters are kept when typing or pasting.
`mask`	`boolean`	`false`	Hides the entered characters in the slots.
`disabled`	`boolean`	`false`	Disables the hidden input and sets the data-disabled attribute.
`autoFocus`	`boolean`	`false`	Focuses the hidden input when the field mounts.
`id`	`string`	—	Id applied to the rendered root element.
`render`	`ReactElement \| ((props, state) => ReactElement)`	—	Replace the rendered element while keeping behavior and accessibility wiring.

`OtpInput.Slot`

Prop	Type	Default	Description
`index`*	`number`	—	Position in the code this slot displays.
`render`	`ReactElement \| ((props, state) => ReactElement)`	—	Replace the rendered element while keeping behavior and accessibility wiring.

`OtpInput.HiddenInput`

Prop	Type	Default	Description
`autoFocus`	`boolean`	—	Focuses this input on mount, overriding the root setting.
`render`	`ReactElement \| ((props, state) => ReactElement)`	—	Replace the rendered element while keeping behavior and accessibility wiring.

Keyboard

Key	Action
`Tab`	Move focus to/from the control
`Enter` / `Space`	Activate when focused (button-like controls)

Accessibility

Uses semantic HTML where possible. Inspect rendered markup in the playground — ARIA is added only when native elements are insufficient.
