What is Basic Authentication?
Basic Authentication, or Basic Auth for short, has been around for ages and is a super simple way for an app to prove itself to a server. You send over a username and password with each request and the server then checks ’em out before letting you in. No messing around with tokens or handshakes just plain old credentials being passed along with every single request.
How does Basic Authentication work?
The username and password are mashed together with a colon in the middle, then encoded into a single string using Base64 and stuck in the request’s Authorization header. The server decodes it and checks the credentials against its records, and then either lets you in or sends you packing. Here’s the catch you need to know: Base 64 is an encoding trick and not encryption so anyone can decode it – meaning Basic Auth is only safe to use if the connection itself is encrypted with HTTPS which does a good job of keeping the header hidden in transit. Because the credentials get sent out every time there’s a request, it’s real easy to set up but a lot less secure than using tokens.
How Onextel can help with Basic Authentication
Onextel has got Basic Authentication covered for the developers who just want something super simple to connect to the API over secure HTTPS to keep those credentials safe. And for teams who want a bit more control, Onextel also does API keys and auth tokens as more robust alternatives – so you can start with Basic Auth and move to more secure methods as your integration grows.
Why it matters
Basic Auth is popular just because it is so easy to work with – most languages and tools have it built in which makes it great for when you just want to test out an integration or do something quick. But since it sends credentials with every single request, it is leaning on HTTPS to stay safe – and it’s not ideal for high security or high volume production setups. Knowing when to use it and when to step up your security game is really the important bit.
