Can Blockchain Solve Mobile Number Data Security Issues?

But there's a catch. This type of authentication poses serious security risks. People tend to reuse simple, easily hacked passwords for multiple accounts. Disclosing one password compromises all the accounts it's linked to, giving hackers access to a massive data set. Verizon's 2025 Data Breach Report notes that approximately 60% of successful data breaches are attributed to human involvement, primarily related to phishing and stolen login credentials.

Access Key Technology Explained
When you sign up for an online service that supports access key authentication, two keys are generated: a public key and a private key. Both are used to authenticate the user when they log in. The public key is stored on the website's server, while the private key is stored on the user's device. Without one, both keys are useless.

Upon login, the server sends a request to the device, chile phone number list which is responded to with a matching access key. The user's identity is also verified at the device level through biometrics. If the key pair matches, the user gains access to their account.

Why are access keys better than passwords?
Access keys are generally considered a more secure and convenient form of authentication than passwords . The user does not need to reset an access key during login attempts, as they would if they forgot their account password. Implementing an access key reduces the risk of forgotten or reused passwords and protects you from phishing attacks because passwords cannot be stolen from a device by a bad actor. Once an access key is created, it is stored on the device associated with it. Even if a cybercriminal acquires a key, they cannot access the account without the matching pair.
