InputOTP demo

A 6-digit verification code, checked when complete, with error and success.

}

Props

Prop	Type and description
`length`	number of digits (default 6)
`value`	string (controlled)
`defaultValue`	string (uncontrolled, default "")
`onChangeText`	(code: string) => void: digits only, on every change including a paste
`onComplete`	(code: string) => void: once each time the last cell is filled
`status`	'error' \| 'success': colours every cell, announced once; the screen clears it
`secure`	boolean: dots instead of digits, hidden from screen readers (default false)
`disabled`	boolean: not editable, dimmed, skipped by FocusChain
`ref`	Ref<TextInput>: the hidden input (focus, blur, clear)
`style`	ViewStyle, layout only, merged last onto the root
`...TextInputProps`	other TextInput props pass through to the hidden input (autoFocus, onFocus, aria-label, accessibilityHint, ...)

Variants

status: error, success

Accessibility

Screen readers read one field, "Code, 6 digits": the name is aria-label, else the FormField label, else "Code", plus the digit count. The cells are hidden.
Inside a FormField the error, or else the description, is its hint.
A new status is announced once ("Code: error"), unless a FormField is already announcing its error.
With secure, the cells show dots and the hidden input is a secure text entry.
When the row of cells is under 48, the root extends the tap area to 48 and a tap there focuses the field.
disabled sets aria-disabled and blocks typing.

Notes

One hidden TextInput drives the cells, so typing, deleting, one-time-code autofill (iOS Keychain/SMS, Android SMS) and paste behave like one field. Non-digits are dropped, so a pasted "123 456" fills every cell. Inside FormField it takes the label, error and disabled; inside FocusChain it joins as one field. Cell size, radius and gap come from the input-otp.cell and input-otp.root Style Slots. Precedence: disabled > status.
