"The biggest guru-mantra is: never share your secrets with anybody. It will destroy you." (Chanakya)
You have probably already heard of OAuth as it is widely used by many online services providers such as Google, FaceBook, LinkedIn, Yahoo, Twitter, ... to name just a few! OAuth is an authentication protocol that allows users to approve application to act on their behalf without sharing their password.
OAuth support was introduced, several years ago, in Jersey 1.x. 'Recently' ... well more than 6 months ago (*), OAuth support has been added to Jersey 2.x, this post post covers in more details the OAuth support added to Jersey 2.3.
If you are not yet familiar with OAuth, it is probably a good time to start to look at this open protocol. The OAuth chapter of the Jersey documentation should be a good starting point.
(*) It's sometime difficult to keep up with the Jersey release cadence! At the time of writing, the current release is Jersey 2.9!
