OpenID is a simple way to log into multiple websites using one basic login account by using a domain name. You might already have an OpenID login, which you might not know about yet.
There are a lot of OpenID providers, but my favourite isis because you can have yourname.mp and not a subdomain like many other OpenID providers. You can see mine here.
But what happens when you want to use your own domain name and not a third party? Well, there is an open-sourced script called phpMyID that you can download which turns your own domain name into an OpenID login.
I have turned my website Jack Cola into my own personal OpenID login. This enables me to log in to any OpenID enabled websites.
Installation is pretty easy. All you have to do is download a small file from thewebsite.
You can either download a tgz or zip file by clicking the highlighted links as seen in the image above.
In the files you have downloaded, there are the basic files such as readme’s and changelogs, just as you would find in any script you download. Pay particular attention to MyID.config.php and MyID.php. These two files are the important ones.
It is best that you upload the files to your server first and edit them online as a few settings need to be checked to make sure your web server is setup correctly. Once you have uploaded your files, visit your website where you have uploaded them. I suggest uploading them to http://yourdomain.com/openID/.
Once uploaded, visit the MyID.config.php file. You will be shown a screen with text similar to this. Click on Login and make sure you can successfully login with the username and password of test.
Make sure you take notice of your Realm. If there is anything after phpMyID, your server is running in safemode and you need to change it in auth_password section. (See below)
To set up phpMyID there are two steps. Edit the MyID.config.php settings and include two lines of code in your webpage’s root directory.
Open up MyID.config.php to edit. The names of the settings are pretty self explanatory.
auth_username: This is your login username. Set it to a username that you will remember.
auth_password: This step is a little tricky. For added security, you need to encrypt your password using the MD5 algorithm. To do this, if you are an Linux or OSX user, you can use openssl. Just type in
$ echo -n 'username:realm:password' | openssl md5
and remember to replace username with your username you specified in auth_username, the realm that was shown on the MyID.config.php page when you viewed it in a web browser, and the password that you want to use as your login.
If you are a Windows user, you can download this app, or use this this website to encrypt your password. If you use the website, make sure you use the entire username:realm:password string is used to generate your password. Once you have your encrypted text, set the auth_username value appropriately.
There are other settings in the config file that you don’t really need to touch (unless you want to). Just read the README file provided and it will explain what they mean.
If you want, you can edit your nickname, email, fullname, dob, gender, postcode, country, language and timezone, to use with the OpenID self registration component. Just remember to uncomment the lines out by deleting the # at the start of each line.
Once you have your auth_password, visit the MyID.config.php webpage and make sure you can log in with your new username and password. If you log in successfully, you will see a screen like this.
If it doesn’t work, have a read in the troubleshooting section in the README file.
Edit your website
Now the authentication is working smoothly, you just have to edit the index (or default) webpage for your website and add two lines of html of code to the head of the file.
<link rel="openid.server" href="http://phpmyid.com/MyID.config.php"> <link rel="openid.delegate" href="http://phpmyid.com/MyID.config.php">
Remember to change the href tag to the location of your MyID.config.php file. Note: If you are using a CMS such as Joomla, you will need to edit the template’s index.php file, and not the actual Joomla root index file.
The Final Step
Well maybe I lied. There is one more step. It is to log in to an OpenID-enabled website to check that everything works properly. I have a WordPress plugin onwhich allows you to register and log in using OpenID. If the website accepts your OpenID log in (and all is working) you will be prompted to enter your username and password. Remember that the OpenID login is your website’s URL.
You should now be logged into that site by using your domain name address. If it doesn’t allow you, try a different website, comment below, read the README file or ask in phpMyID’s.
