Reactnative asyncstorage for a specific user is not working properly

Question

I am trying to save the passing screen after a user that is logged in, has passed the test. And that passing screen is saved even after the app is completely closed. For this purpose, I am using asyncstorage but the problem is that if once for a user, a passing screen is saved, even if a new user logs in, he does not even get the test sheet, the app directly lands on the passing screen even for a completely new user. I will be grateful if someone helps, i am stuck here for past 3 days. Here is the code:

For test.js:

import AsyncStorage from '@react-native-async-storage/async-storage';


   const key = auth().currentUser.uid + "hasPassed"
  

 export const hasPassed = async () => {
     return AsyncStorage.getItem(key).then(result => result != null ? JSON.parse(result) : undefined).catch(e => console.log(e))    
 }

 export const setHasPassed = async (newPassed) => {
     return AsyncStorage.setItem(key, JSON.stringify({hasPassed: newPassed})).catch(e => console.log(e))
 }
export default test =({navigation}) => { 


  const [index, setind] = useState(0);
  const [idis, setidis] = useState(false);
  const [count, setcount] = useState(0);
  const [error, setError] = useState('');
  const [results, setResults] = useState('');
  const [disb, setdis] = useState(true);
  const [ndisb, setndis] = useState(true);

 useEffect(() => {
   //Setting callbacks for the process status
   Voice.onSpeechStart = onSpeechStart;
   Voice.onSpeechEnd = onSpeechEnd;
   Voice.onSpeechResults = onSpeechResults;
   Voice.onSpeechError = onSpeechError;

   return () => {
    //destroy the process after switching the screen
    Voice.destroy().then(Voice.removeAllListeners);
   
    
  };
}, []);

check function for test.js:

function Check() {
  if (results.includes(words[index])){
   // console.log(index);
    Alert.alert('Correct!','You are learning so well!');
    
     if(index==7) {
      if(count<5)
      {
             setHasPassed(true).then(() => setshowpass(true))
      }
      else{
        Alert.alert('fail','fail');
      }
    }
    if (index==7){
      setndis(true);
      setdis(true);
      setidis(true);
    }
    else{
   setndis(false);
   setdis(true);
   setidis(true);
    }
   
  }
  else{
    Alert.alert('Ops!','Looks like you went wrong somewhere. Try again!');
    setcount(count+1);
    console.log('uc',count);
    setdis(true);
    setndis(true);
   
    if(count==5){
      Alert.alert('Restest', 'Looks like you had way too many mistakes!')
      setind(0);
      setcount(0);
      setdis(true);
    }
  }
}




     const words=['word1', 'wor2', 'word3', 'word4', 'wrd5', 'word6', 'wor7', 'w8'];
      
      
        const [showpass, setshowpass]=useState(false);

useEffect(() => {
        const getState = async () => {
          const result = await hasPassed()
          setshowpass(result ? result.hasPassed : false)
      }
      getState()
      }, []);

      if (showpass === undefined) {
        return null
     }

return (
    <View style={styles.body}
    >

        <Modal
          transparent={false}
          visible={showpass}
         animationType='slide'
          hardwareAccelerated 
          >
            <View style={styles.body}>
              <Text style={styles.toptext}>Congratulations!</Text>
              <Text style={styles.toptext}>Worked great in Turkishya!</Text>
              <Text style={styles.topptext}>
                And mastered the skill 'Alphabets'
              </Text>
            </View>
            </Modal>
<View>
);
