Allow my staff to tweet to my company Twitter account through my website



I have a company Twitter account, and I want to build a very simple web application that allows my staff/employees to post tweets to the account, through this form. That way I do not have to run the risk of handing out the company’s Twitter credentials.

What is the process for authorizing this? Can I embed the username and password in the App, or do I need to use OAuth and use the various keys/tokens/secrets that are required?
