How to clear the login information recorded by the browser after obtaining the AuthorizationCode ？

How to clear the login information recorded by the browser after obtaining the AuthorizationCode using 'https://secure.sg1.adobesign.com/public/oauth/.....'

When we call ''https://secure.sg1.adobesign.com/public/oauth/.....' again to get the AuthorizationCode directly, no need to log in, after getting the AuthorizationCode each time, is there any way we can clear the browser cached login information?
