React Native Toggle Password Visibility

Professionally built mobile app templates to kickstart your project

The toggle password visibility helps for a good user experience and lets the user see and confirm what they are typing.

And in most cases, it can even completely eliminate the need for a confirm password field.

Why The Confirm Password Field is Useless

So let’s get into it.

Step 1:

Download the eye-close and eye-open icon from Flaticons here.

Step 2:

Set the toggle state for the password visibility in the constructor and write the functions

constructor(props){
super(props);
this.state = {
 hidePassword: true
}
}

//Toggle password visibility
managePasswordVisibility = () => {
    this.setState({hidePassword: !this.state.hidePassword});
  };

Step 3:

Next, import these downloaded icons to your project. Also import TextInput from React Native

<View style={[styles.container, {marginBottom: 18}]}>
                <TextInput
                  style={styles.inputFlex}
                  secureTextEntry={this.state.hidePassword}
                  autoCompleteType="password"
                  autoCapitalize="none"
                  autoCorrect={false}
                  returnKeyType="send"
                  onChangeText={(UserPassword) =>        this.setState({UserPassword})}
                />
                <TouchableOpacity
                  activeOpacity={0.8}
                  style={styles.visibilityBtn}
                  onPress={this.managePasswordVisibility}>
                  <Image
                    source={
                      this.state.hidePassword
                        ? require('../assets/images/show.png')
                        : require('../assets/images/hide.png')
                    }
                    style={styles.btnImage}
                  />
                </TouchableOpacity>
              </View>
            </View>

Step 3:

Finally, we’ll add some styling

const styles = StyleSheet.create({

container: {
flex: 1,
    flexDirection: 'row',
    flexWrap: 'nowrap',
    marginTop: 10,
  },
inputFlex: {
    alignSelf: 'stretch',
    width: '100%',
    padding: 0,
    backgroundColor: '#ddd'
  },
visibilityBtn: {
    position: 'absolute',
    right: 9,
    height: 25,
    width: 25,
    padding: 0,
    marginTop: 21,
  },

})

Full Code Here:

import { Component }, React from 'react';
import { View, Text, TextInput, TouchableOpacity, Stylesheet } from 'react-native';


class App extends Component {

constructor(props){
super(props);
this.state = {
 hidePassword: true
}
}

 //Toggle password visibility
 managePasswordVisibility = () => {
    this.setState({hidePassword: !this.state.hidePassword});
  };

render(){
return(
<View style={[styles.container, {marginBottom: 18}]}>
                <TextInput
                  style={styles.inputFlex}
                  secureTextEntry={this.state.hidePassword}
                  autoCompleteType="password"
                  autoCapitalize="none"
                  autoCorrect={false}
                  returnKeyType="send"
                  onChangeText={(UserPassword) =>        this.setState({UserPassword})}
                />
                <TouchableOpacity
                  activeOpacity={0.8}
                  style={styles.visibilityBtn}
                  onPress={this.managePasswordVisibility}>
                  <Image
                    source={
                      this.state.hidePassword
                        ? require('../assets/images/show.png')
                        : require('../assets/images/hide.png')
                    }
                    style={styles.btnImage}
                  />
                </TouchableOpacity>
              </View>
            </View>

)

}

}

const styles = StyleSheet.create({

container: {
flex: 1,
    flexDirection: 'row',
    flexWrap: 'nowrap',
    marginTop: 10,
  },
inputFlex: {
    alignSelf: 'stretch',
    width: '100%',
    padding: 0,
    backgroundColor: '#ddd'
  },
visibilityBtn: {
    position: 'absolute',
    right: 9,
    height: 25,
    width: 25,
    padding: 0,
    marginTop: 21,
  },

})

export default App;
