authentication

AWS Console information. Reading the userInfo cookie information to display, alert, or anything else you want.
For example, include a banner on your AWS console with highlighting when you login as "AWS Administrator" role.
This can then be used in various applications.

sample code that "grabs" the userInfo and create an banner alert

javascript:(function () {
    function fullDecode (input) {
        let decoded = decodeURIComponent(input);
        return (decoded == input ? decoded : fullDecode(decoded))
    };
    let userInfo = document.cookie.replace(/(?:(?:^|.*;\s*)aws-userInfo\s*\=\s*([^;]*).*$)|^.*$/, "$1");
    alert(JSON.stringify(JSON.parse(fullDecode(userInfo)), null, 4))
})();

sample code that "grabs" the userInfo and outputs in the console

let userInfo = document.cookie.replace(/(?:(?:^|.*;\s*)aws-userInfo\s*\=\s*([^;]*).*$)|^.*$/, "$1");
let decoded = decodeURIComponent(userInfo);
JSON.stringify(JSON.parse(decoded), null, 1);
