Top Five Tips to Secure Your App From Hackers

Besides securing your data, you should also implement strong authentication and encryption. For example, you should use AES encryption for key exchange. SSL and VPNs are great ways to protect your App. Token-based security is also recommended. These methods authenticate legitimate requests while making it difficult for hackers to access your data. And, of course, you can also hire an app development company to build a secure app. These are the top five tips to secure your App from Hackers.

Strong encryption

While the majority of mobile apps use some form of encryption to prevent the hacking of sensitive information, some don’t. While this is not an ideal situation, it can still protect your app from being hacked. Encryption works by scrambling plain text messages so that only the person with the key can decrypt them. This protects your users’ personal information and prevents criminals from reading it. Organisations such as the NSA and FBI have asked for permission to decrypt messages sent through WhatsApp.

The key management of encryption is crucial. Encryption keys must not be stored locally, as they are easily stolen. Hard-coding keys is also dangerous as they can be used by hackers to gain access to the device. Always use the latest APIs and standards for encryption. SHA-256 and MD5 hashing are the most common cryptographic protocols used today. To further protect your app from being hacked, use two-factor authentication. Always use a secure service when using two-factor authentication. SMS cannot provide strong authentication and can be easily stolen by hackers.

For more protection, use strong encryption for sensitive data. For example, AES encryption is ideal for key exchanges. Make sure to filter all user input to avoid malicious code injection. In addition, use token-based security to authenticate legitimate requests. This method is effective for securing user accounts and data, but it doesn’t guarantee complete security. As an added precaution, don’t store passwords on the device.

Encryption is also essential for the mobile environment. Since sessions are longer than on the desktop, it’s not wise to use the same session for mobile devices. Instead, use tokens instead of identifiers. Also, make sure your app provides remote log off and wipe off functions. Remember, key management is a crucial part of encryption, and you shouldn’t use hard-core encryption keys.

Strong authentication

Encrypting communications in your app is a must if you want to keep it safe from hackers. A combination of passwords and client certificates can help prevent any unauthorised access to your app. Strong authentication can also be combined with device ID or one-time passwords to prevent unauthorised access to sensitive information. You can also implement time-of-day and location-based restrictions for users to limit when they can use your app. Be aware of potential snooping or man-in-the-middle attacks over cellular or wireless networks. To keep your app safe from these threats, make sure all communications between your mobile app and your app server are encrypted using 4096-bit SSL keys.

Aside from passwords, you can also use two-factor authentication to protect your app against hackers. These two-factor authentication methods are more secure than password alone, and are more likely to withstand large-scale hacking attempts. To further secure your app, consider hardware security keys. Dropbox, GitHub, and Microsoft all support hardware security keys. You may also want to use these keys if you have a sensitive account with one of these services.

When using Javascript in your app, you should guard each authentication layer with different tags. For example, your app’s second authentication layer might require users to enter their phone number in order to get a one-time passcode. In such cases, hackers cannot get the one-time passcode without a user’s password. However, you should use strong passwords in your app, and never ask users for their personal information.

Another essential component of app security is encryption. While it may not seem like it, hard coding your keys is a major security risk. Keys are not stored locally on the device, and once stolen, they can be used to gain control of the device. SHA-256 and MD5 are popular cryptographic protocols. You can use the latest APIs to implement cryptography in your app, as well as the latest encryption standards.


If you’re developing an App for your business, you might want to consider using VPNs to make your App secure from hackers. These services encrypt your data using sophisticated encryption methods. Two-factor authentication, or two-FA, ensures that your data cannot be intercepted or copied. This security feature requires users to enter a passcode sent to their mobile device, as well as their fingerprint or facial recognition to log in. You should also check your VPN’s location, as this may play a role in fast speeds.

In addition to encryption, VPNs can detect malware and protect your data from viruses, ransomware, and phishing scams. Additionally, most VPNs claim to offer top encryption standards. Look for one that offers AES 256-bit encryption. VPNs with this standard are the most secure. The best ones will prevent your data from being intercepted by any third-party. This means that your data is completely secure.

Despite the importance of encryption, a compromised VPN can be a major security risk. A compromised VPN can be used to steal online banking credentials or spy on ISPs. A compromised VPN can also allow hackers to access connected devices and blackmail users with ransomware. VPNs aren’t a guarantee against these threats, but they do help to reduce the risk of having your data breached by hackers.

VPNs are especially important for online shopping. While it may seem untrustworthy to purchase something online, you never know who might be watching you. A VPN will help you protect your financial details and ensure your purchases are safe. The average user data leaks out on the internet every 39 seconds. In addition, large tech companies make billions by selling user data to advertisers. In addition to the infamous Facebook data scandal, 47 states do not have strong data privacy laws to protect you.


The most critical factor in securing your App from Hackers is to ensure that it is built using secure technologies. Hackers can exploit vulnerabilities in security protocols or application programming interfaces. If a developer caches authorization information locally, a cybercriminal could hijack the information and use it to access other parts of the app. This is why it is essential to develop a strong API security strategy. Here are some ways to ensure that your APIs are secure.

Encryption is another important factor. HTTPS uses Secure Sockets Layer (SSL) encryption to protect data during transmission over a network. HTTP data is not encrypted and has no validation, allowing hackers to spy on what users view and do. To secure your app against hackers, you must use HTTPS protocol and a valid SSL certificate on the server. If you cannot afford the SSL certificate, there are free options that are still effective.

Encryption is critical to protecting data. Avoid hard coding keys as this makes the keys easier to steal. Encryption should never be stored locally on the device. Also, use popular cryptographic protocols such as SHA-256 or MD5 hash. Modern security standards recommend using the latest APIs and encryption standards in order to protect your application. If you don’t want to worry about decompilation, use Xamarin, a cross-platform development tool.

To make your App more secure from Hackers, use the principle of least privilege. Code should only be permitted to use resources it needs to perform its function. Never grant any application more privilege than necessary. And don’t reuse libraries that were previously used for other purposes. And don’t forget to always do threat modeling on your code updates. By following these tips, you’ll be on the way to securing your app.


One of the most common ways to get your OAuth credentials is through credential stuffing. This is a process where attackers purchase access to a user’s credentials on the dark web. They then use these credentials to gain control of a legitimate account. Additionally, their OAuth token can be obtained through phishing or public repositories on GitHub. Once stolen, this token can be used by anyone until it expires. Another common method is to poke around in the code to find hidden API vulnerabilities. Once they have access to the OAuth code, they can then log in to the victim’s account in any client application.

To make sure your OAuth tokens are secure, you need to protect the scope of access granted. When using an authorization code, the user must first approve the access granted. The resulting token allows the client application to access only the scope that the user has approved. Because of flawed validation, an attacker can upgrade the access token to grant it extra permissions. To do this, the attacker needs to know the type of grant that the user has given to the client application.

One way to protect user credentials is to make sure that they are not stored on the device or private space. Token-based authentication is a great way to prevent this from happening. Token-based authentication allows the app to make requests on behalf of the user and avoids the risk of losing or compromising user passwords. Also, refresh user sessions every so often. By expiring user sessions, you prevent hackers from using stolen authentication information.
