As we all know, Yahoo! Messenger is the popular instant messaging client which helps as communicate by writing text, making PC-to-PC calls, sharing pictures and many more. Usually, Yahoo! Messenger should be downloaded and installed as a stand-alone application on your desktop. But there's also another way of logging into your account.

Besides using Yahoo Messenger as a standalone application, there's one more way to have access to your account and chat with your friends. Say you are using a computer on a 'Guest' account without having Yahoo! Messenger installed. If it's a restricted account, you may not have privileges for downloading and installing programs. What can you do?

Or let's say you are using a machine with an operating system you are not so familiar with as far as installing apps, but you can work your way into opening a Web browser. There's the solution. You can start chat from any web browser (Internet Explorer, Firefox, Opera, Safari, etc.). No download required. Available in multiple languages.

Go to http://messenger.yahoo.com/webmessenger.php, click on the 'Get Started' button and you will be taken to Yahoo! webmessenger's login page.

Click on 'Sign In' in order to enter your user name and password. You need to be careful, though and set your browser or pop-up blocker to allow pop-ups. Otherwise you won't be able to use the Yahoo! webmessenger.

For example, Firefox shows a yellow bar on top of your browser saying that 'Firefox prevented this site from opening a popup window'. You need to click the 'Options' button and select to allow pop-ups for webmessenger.yahoo.com. Next, you'll have to agree to be taken to an encrypted page.

After pop-ups were allowed, you can click again the 'Sign In' button. The following window will pop up. Click 'Yes' to continue to Yahoo! webmessenger. Now, all you have to do is fill in your user name and password and you're ready for a chat session.
