Your mobile device stores a lot of information, including photos, documents, and possibly even your bank account information. With so much at stake, it’s important to make sure your device is secure by making the right security decisions when it comes to which apps you use and how you use them. These seven tips can help ensure your device remains safe from hackers who might want to steal personal information, financial information, or sensitive company information through your mobile applications.

Install Apps from Trusted Sources

Most security breaches happen when an app is installed. There are some tips you can follow to install apps securely. Choose carefully when downloading free apps, especially those with ads. If you aren’t sure about an app, ask your friends or check review sites. Make sure you pay attention to permissions requested by applications before installing them on your device—some apps need access to sensitive data like your contacts list and photos, so read through what they’re asking for and choose wisely. Install operating system updates as soon as they become available, or manually download them through your device's settings menu; major OS updates often include patches that fix security problems that could compromise your device if left unpatched.


Use Two-Factor Authentication (2FA)


Since most data loss originates from theft, you can do your best to ensure your data is safe by using two-factor authentication on all accounts that offer it. This way, if someone tries to log into an account using only a password, they’ll need access to your phone too. If they try to log in via an app? Well, you should delete that account now because it’s probably already been compromised. It may seem like a hassle at first, but 2FA will help keep your accounts safer in the long run.

Enable Strong Passwords

Passwords should be a mix of letters, numbers and special characters. Longer passwords are stronger, so take advantage of password requirements that force you to use a minimum length, such as eight or more characters. Check out tools like LastPass and 1Password if you have trouble remembering different passwords for all your accounts. If password security is a problem that's always been difficult for you, consider using two-factor authentication on your smartphone instead of long passwords.

Avoid Cloud Sync Services

Antivirus software is a must-have for mobile devices. You never know when an app will become infected, causing all sorts of havoc on your phone or tablet. It’s also important to make sure you have up-to-date antivirus software on your devices; malware authors tend to target older operating systems and apps. Use common sense about what apps you install, too; if something seems like it should be free (or shouldn’t be), then it likely is (and isn’t).

Maintain Antivirus Software

This might seem obvious, but it’s important to install antivirus software on your device and ensure it’s up-to-date. It's not only important for security reasons, but also because unpatched systems will be less stable, especially when you’re dealing with 3rd party apps.

Don't Jailbreak your Device

Software is updated more frequently on mobile devices than on computers. In fact, Apple updates iOS devices more than seven times a year! If an app hasn’t been updated in awhile, it may be exposing your device to security risks. Apps can also have vulnerabilities that haven’t been discovered yet. As a result, keep your apps up-to-date and remove any apps you don’t use or need anymore. Make sure every app has a current security patch before downloading—this goes for free and paid apps alike!

Update Often

iOS and Android both receive regular updates. That means keeping your device updated and downloading any security patches released will ensure you’re using a more secure version of iOS or Android than if you hadn’t updated. This is especially important for jailbroken devices, which may not receive security patches from third-party sources. Keeping your device updated will make it harder for malicious actors to penetrate your network by taking advantage of known vulnerabilities in older versions of iOS or Android. In general, avoiding older software is also a good rule of thumb when it comes to apps.


It's important to note that mobile application security is a dynamic field, and these are only best practices for today. What may be secure today could be outdated tomorrow, so always make sure you're aware of updates and new findings. Keeping your mobile applications safe is your responsibility, but there are tools available—and plenty of avenues for research—to help you achieve that goal. The more educated you are about what’s at stake, the better prepared you’ll be when an attack occurs and in avoiding them altogether by choosing more secure software development practices and identifying potential issues before they go live with your app. You should connect with the PixelCrayons team and Hire mobile app developers that implement a solid security protocol for your users and give them peace of mind.
