You must stringify your object.

AsyncStorage.setItem(ACCESS_TOKEN, JSON.stringify(responseData), (err)=> {
    if(err){
        console.log("an error");
        throw err;
    }
    console.log("success");
}).catch((err)=> {
    console.log("error is: " + err);
});

And when you read it, you should parse it.

try {
    const value = await AsyncStorage.getItem(ACCESS_TOKEN);
    if (value !== null) {
        // We have data!!
        console.log(JSON.parse(value));
    }
} catch (error) {
    // Error retrieving data
}
