# SecureField

A SwiftUI SecureField component for password input.
iOS, tvOS, Included in Expo Go

> For the complete documentation index, see [llms.txt](/llms.txt). Use this file to discover all available pages.

Expo UI SecureField matches the official SwiftUI [SecureField API](https://developer.apple.com/documentation/swiftui/securefield) and provides a text field that masks user input for passwords and other sensitive text.

## Installation

```sh
npx expo install @expo/ui
```

If you are installing this in an [existing React Native app](/bare/overview), make sure to [install `expo`](/bare/installing-expo-modules) in your project.

## Usage

### Basic secure field

```tsx
import { useState } from 'react';
import { Host, SecureField } from '@expo/ui/swift-ui';

export default function BasicSecureFieldExample() {
  const [password, setPassword] = useState('');

  return (
    <Host matchContents>
      <SecureField placeholder="Password" onValueChange={setPassword} />
    </Host>
  );
}
```

### Submit handling

Use the [`submitLabel`](/versions/v56.0.0/sdk/ui/swift-ui/modifiers#submitlabelsubmitlabel) and [`onSubmit`](/versions/v56.0.0/sdk/ui/swift-ui/modifiers#onsubmithandler) modifiers to handle form submission from the keyboard.

```tsx
import { useState } from 'react';
import { Host, SecureField } from '@expo/ui/swift-ui';
import { submitLabel, onSubmit } from '@expo/ui/swift-ui/modifiers';

export default function SecureFieldSubmitExample() {
  const [password, setPassword] = useState('');

  return (
    <Host matchContents>
      <SecureField
        placeholder="Password"
        onValueChange={setPassword}
        modifiers={[submitLabel('done'), onSubmit(() => console.log('Login submitted'))]}
      />
    </Host>
  );
}
```

### Imperative ref

Use a ref to imperatively set text, focus, or blur the secure field.

```tsx
import { useRef } from 'react';
import { Host, SecureField, SecureFieldRef, Button, HStack, VStack } from '@expo/ui/swift-ui';
import { buttonStyle } from '@expo/ui/swift-ui/modifiers';

export default function ImperativeSecureFieldExample() {
  const ref = useRef<SecureFieldRef>(null);

  return (
    <Host matchContents>
      <VStack>
        <SecureField ref={ref} placeholder="Password" />
        <HStack spacing={12}>
          <Button
            modifiers={[buttonStyle('bordered')]}
            onPress={() => ref.current?.focus()}
            label="Focus"
          />
          <Button
            modifiers={[buttonStyle('bordered')]}
            onPress={() => ref.current?.blur()}
            label="Blur"
          />
          <Button
            modifiers={[buttonStyle('bordered')]}
            onPress={() => ref.current?.setText('secret123')}
            label="Set Text"
          />
        </HStack>
      </VStack>
    </Host>
  );
}
```

## API

```tsx
import { SecureField } from '@expo/ui/swift-ui';
```

## Component

### `SecureField`

Supported platforms: iOS, tvOS.

Type: React.[Element](https://www.typescriptlang.org/docs/handbook/jsx.html#function-component)<[SecureFieldProps](#securefieldprops)\>

Renders a SwiftUI `SecureField` for password input.

SecureFieldProps

### `autoFocus`

Supported platforms: iOS, tvOS.

Optional • Type: `boolean` • Default: `false`

If true, the secure field will be focused automatically when mounted.

### `children`

Supported platforms: iOS, tvOS.

Optional • Type: `React.ReactNode`

Slot children - supports `<SecureField.Placeholder>` with a `<Text>` child

### `maxLength`

Supported platforms: iOS, tvOS.

Optional • Type: `number`

Maximum number of characters allowed. Truncates natively as the user types.

### `onFocusChange`

Supported platforms: iOS, tvOS.

Optional • Type: `(focused: boolean) => void`

A callback triggered when the field gains or loses focus.

### `onTextChange`

Supported platforms: iOS, tvOS.

Optional • Type: `(text: string) => void`

A callback triggered when the text value changes.

If the callback is marked with the `'worklet'` directive, it runs synchronously on the UI thread; otherwise it is delivered asynchronously as a regular JS event.

### `placeholder`

Supported platforms: iOS, tvOS.

Optional • Type: `string`

A text that is displayed when the field is empty.

### `ref`

Supported platforms: iOS, tvOS.

Optional • Type: Ref<[SecureFieldRef](#securefieldref)\>

### `text`

Supported platforms: iOS, tvOS.

Optional • Type: [ObservableState](#observablestate)<string\>

An observable state that holds the current text. Create one with `useNativeState('')` or `useNativeState('initial value')`. If omitted, the field manages its own internal state.

#### Inherited Props

-   [CommonViewModifierProps](/versions/v56.0.0/sdk/ui/swift-ui/modifiers)
