Tips for securely concealing login details during an API call

As a newcomer to the world of Javascript and Vue.js, I am eager to expand my knowledge in these areas. However, I have encountered an issue while attempting to call an API login that exposes a password in the request payload.

It seems quite insecure to have the password displayed like this. Can anyone offer suggestions on how to conceal it from the browser?

I would greatly appreciate any help or advice. Thank you!

Answer №1

This particular topic is quite weighty and the query at hand lacks specificity, prompting me to make certain assumptions as I address it.

Referencing an API login that reveals a password in the request payload

It seems like you may be referring to situations where the password is visible when inspecting requests in the browser's developer tools.

If this is indeed the case, it should be noted that such visibility is expected and cannot be completely eliminated. Some individuals mistakenly believe that this lack of encryption necessitates developing custom solutions to obscure sensitive data. However, it is important to remember that modern browsers automatically handle encryption as long as https is utilized. The encryption process occurs after the request leaves the browser, ensuring that the content remains hidden from prying eyes during transit to the designated server. Introducing additional layers of encryption can introduce unnecessary complexity; moreover, if the encryption key is also transmitted, it becomes accessible to potential eavesdroppers. Furthermore, endpoints within the target server are already secured with encryption, allowing sensitive information to be passed even via GET requests without intermediaries deciphering its contents. It is advisable, however, to favor using POST requests due to benefits such as avoiding storing values in URL caches and reducing the likelihood of data being preserved in server logs.

  • Proper utilization of https guarantees encrypted transmission of data between the browser and server.
  • For transmitting sensitive information, prefer employing POST requests.
  • Avoid tacking on customized encryption mechanisms atop https, as doing so can introduce more complications than security enhancements.

Additionally, there are considerations regarding whether to store tokens in LocalStorage versus cookies. While a definitive verdict on superiority remains elusive, both storage methods can be secure provided appropriate safeguards are implemented (though safeguarding cookies by preventing JavaScript access may enhance their security, albeit potentially complicating operations within Single Page Applications).
