Get Logged-In User’s Key Info

Want to retrieve useful details about the currently logged-in Salesforce user using Apex? Whether you’re building a user dashboard or adding logging functionality, knowing how to fetch user locale, time zone, and last login date can really come in handy.

In this blog post, we’ll walk through a clean and simple Apex method that pulls all three packaged neatly in a custom wrapper class.

If you’re just starting out in Apex, this is a perfect example to help you understand:

• How to use the UserInfo class

• How to query user data from the User object

• How to return multiple values using a wrapper

Let’s get started! 

🧠 What Are We Trying to Do?

We want to build a method that:

• Uses built-in Salesforce functions to get locale and time zone

• Uses a SOQL query to get the user’s last login date

• Returns all this info together in a single custom class (wrapper)

This way, we can reuse this logic anywhere maybe for analytics, a login audit feature, or even just to display it in a custom UI component.

🔍 Code Explanation

public class ApexUseCaseTwenty {
    
    public static UserInfoWrapper getLoggedInUserInfo(){

We start with a class named ApexUseCaseTwenty, and create a static method getLoggedInUserInfo which will return all the user details wrapped inside a custom object.

        UserInfoWrapper wrapper = new UserInfoWrapper();

We create an instance of our custom UserInfoWrapper class to hold all the data.

        wrapper.localeInfo = UserInfo.getLocale();
        wrapper.timezoneInfo = String.valueOf(UserInfo.getTimeZone());

The UserInfo class provides built-in methods like:

• getLocale() – returns the user’s locale setting (like en_US)

• getTimeZone() – returns the user’s time zone (as a TimeZone object, which we convert to string)

        String userId = UserInfo.getUserId();
        List<User> userRecord = [SELECT Id, LastLoginDate FROM User WHERE Id = :userId LIMIT 1];

We use getUserId() to fetch the ID of the current user, and then run a simple SOQL query to get their LastLoginDate.

        if(userRecord.size() > 0){
            if(userRecord[0].LastLoginDate != null){
                wrapper.lastLoginInfo = userRecord[0].LastLoginDate;
            }
        }

We safely check if the record was found and if LastLoginDate is not null, and then store it in the wrapper.

        return wrapper;
    }

Finally, we return the populated wrapper.

    public class UserInfoWrapper{
        public DateTime lastLoginInfo;
        public String localeInfo;
        public String timezoneInfo;
    }
}

This nested class UserInfoWrapper holds all three values we need to return.

✅ Why This Is Useful

You can use this pattern in a variety of real-world scenarios:

• Show last login and location settings in user profiles

• Log user info during transactions or support requests

• Dynamically customize content based on user’s time zone or locale

Plus, this approach is clean, reusable, and easy to expand — just add more fields to the wrapper if needed!

🧾 Final Code Snippet

public class ApexUseCaseTwenty {
    public static UserInfoWrapper getLoggedInUserInfo(){

        UserInfoWrapper wrapper = new UserInfoWrapper();
        wrapper.localeInfo = UserInfo.getLocale();
        wrapper.timezoneInfo = String.valueOf(UserInfo.getTimeZone());

        String userId = UserInfo.getUserId();
        List<User> userRecord = [SELECT Id, LastLoginDate FROM User WHERE Id = :userId LIMIT 1];
        if(userRecord.size() > 0){
            if(userRecord[0].LastLoginDate != null){
                wrapper.lastLoginInfo = userRecord[0].LastLoginDate;
            }
        }

        return wrapper;
    }

    public class UserInfoWrapper {
        public DateTime lastLoginInfo;
        public String localeInfo;
        public String timezoneInfo;
    }
}
