📌 Secure Token Storage Summary
Secure token storage refers to the safe handling and saving of digital tokens, such as authentication tokens, session tokens, or API keys, to protect them from unauthorised access. These tokens often grant access to sensitive systems or data, so storing them securely is crucial to prevent security breaches. Best practices include using encrypted storage areas, restricting token access to necessary applications only, and regularly rotating and invalidating tokens to reduce risk.
🙋🏻♂️ Explain Secure Token Storage Simply
Imagine a token is like a key to your house. You would not leave your house key lying around where anyone could take it, so you might keep it in a locked drawer or on a secure keychain. Similarly, secure token storage means keeping digital keys in a locked place on your device or server, so only trusted people or software can use them.
📅 How Can it be used?
Use secure token storage to keep user authentication tokens safe in a mobile banking app to protect accounts from unauthorised access.
🗺️ Real World Examples
A mobile app for online banking stores access tokens in a protected section of the device, such as the iOS Keychain or Android Keystore, so that even if someone hacks the app, they cannot easily steal the tokens and access user accounts.
A web service that connects to a cloud provider saves its API keys in an encrypted environment variable or a secrets manager, ensuring that only the service can read the key and preventing exposure if the server is compromised.
✅ FAQ
Why is it important to store tokens securely?
Tokens often act as the keys to your digital castle, providing access to sensitive accounts and data. If someone gets hold of these tokens, they might be able to impersonate you or access private information. Storing tokens securely helps keep your accounts and data safe from unauthorised users.
What are some simple ways to keep my tokens safe?
A good approach is to use encrypted storage so that even if someone finds the tokens, they cannot read them easily. Limiting access to only the apps or people who really need them also helps. Regularly changing your tokens and removing old ones makes it much harder for anyone to misuse them.
What could happen if tokens are not stored securely?
If tokens are left unprotected, cybercriminals could use them to access accounts, steal data, or even take control of systems. This can lead to data breaches, financial loss, and damage to reputation. Proper token storage is a simple but powerful way to avoid these problems.

Order Management
Order management is the process of tracking and handling customer orders from the moment they are placed to when they are delivered. It involves receiving the order, checking stock, processing payment, organising shipping, and updating customers on their order status. Good order management helps businesses ensure customers receive the right products quickly and accurately.
Agile Enablement Services
Agile Enablement Services are support activities and resources provided to help organisations adopt and improve agile ways of working. These services might include training, coaching, mentoring, and providing tools or frameworks that make it easier for teams to work in an agile manner. The goal is to help teams become more flexible, collaborative, and responsive to change by guiding them through agile practices and principles.
Dynamic Code Analysis
Dynamic code analysis is the process of examining a program while it is running to find errors, security issues, or unexpected behaviour. This method allows analysts to observe how the software interacts with its environment and handles real inputs, rather than just reading the code. It is useful for finding problems that only appear when the program is actually used, such as memory leaks or vulnerabilities.
Network Security
Network security is the practice of protecting computer networks from unauthorised access, misuse, or attacks. It involves using tools, policies, and procedures to keep data and systems safe as they are sent or accessed over networks. The aim is to ensure that only trusted users and devices can use the network, while blocking threats and preventing data leaks.
Quantum-Resistant Cryptography
Quantum-resistant cryptography refers to methods of securing digital data so that it remains safe even if quantum computers become powerful enough to break current encryption. Traditional cryptographic systems, like RSA and ECC, could be easily broken by quantum computers using specialised algorithms. Quantum-resistant algorithms are designed to withstand these new threats, keeping data secure for the future.
